Internet module ecoNet 300 and ecoLINK2

jamrjan 184752 679
Best answers

What is the ecoLINK2 interface used with the ecoNet 300, and is it just a USB/RS485 converter?

ecoLINK2 is basically an RS485 converter, but the ecoNET300 setup uses more than a plain adapter: the controller goes through ecoLINK2 into the ecoNET300, and only that combination establishes communication with the server [#17778027] A normal RS485→USB converter can still let you listen to the controller on a PC, but it does not make ecoNET300 work by itself [#17778027] The controller side uses the G1/G2 RS485 ports; one reply says USB is only for software updates, while G1 is for the ecotouch panel and G2 for ecoNET, with the same data on both buses [#17757514] The interface is tied to FTDI-based hardware; the forum explicitly says ecoLINK2 uses an FTDI chip and that CH340-based converters are not supported by the ecoNET software [#19663291] Even when raw RS485 data is captured, it is not useful without the frame structure/decoder, because the protocol is closed and not Modbus [#17756899]

    Good evening, I'm new to this forum and I have a question and I hope someone can help me. I have a Kostrzewa stove with the ecoMax 860P3 module and today I connected the econet300 internet module. It writes econet24 and I connected it to G4 without an adapter because it was missing in the package. I cut off the cable and connected without. The module is connected to the internet via wifi and the connection is stable. In the information about the stove in the 4pellets version, it shows me 0.0.0 and on the website there is information that the module is not compatible with my Module 860P3. This module is described in the manual. Does anyone know about this and can help me? Regards.

    What do you mean by "I connected it to the G4 without an adapter because it was missing in the package"?

    I cut off the end and connected the cables as it was written in the description on the cable.

    It seems that you have a friend econet not under fescue. Unfortunately, they are branded and are not interchangeable.

    Hello,
    Can someone help me to send this data to Domoticz?
    I have an external temperature sensor on display, and I would like to have this reading in Domoticz. Generally, there is a lot of cool information that I would like to include in Domoticz...
    I have econet300

    Sorry for the delay, but I'll give you a hint :)

    By way of introduction:
    The entire system is installed on Raspberry Pi 4b, i.e.: domoticz, mqtt-mosquito broker, python.

    You create a script in Python, e.g. like this
    Code: Python
    Log in, to see the code


    You can name the file with this code whatever you want, it only needs the extension .py and you can place it wherever you want on the raspberry.
    You then edit the crontab file on your system with a command in the terminal

    crontab -e

    and at the end of this litany displayed in green, you enter when the script should run
    Code: text Expand Select all Copy to clipboard
     */1 * * * * python  /home/pi/domoticz/plugins/Biawar/biawar.py


    As you can see above, there is a path to the script file. I named it Biawar.py

    Why this and not a loop in python? the loop may hang and cron calls the script once every minute (in my case).

    you change the idx in the script to the one you will have in domoticz.

    The python script is written based on the information provided in this topic.
    This is not my script, I just modified it for myself. The original version is posted somewhere earlier in this topic.


    Edit:
    I corrected the python code, and more specifically the description of the IP address. It should be the IP address of the mqtt broker, not domoticz.

    Ok, service counters are in editParams. I managed to send it all to HomeAssistant as entities and sensors, so if anyone needs a hint, I'm here to help.

    Do you know how to read the following thing from the parameters?: Ecoster mode can be "Schedule", "Comfort", "Economy", etc. I can handle it. But I also need to distinguish in the "Schedule" mode whether day or night mode is active at a given moment. Do you understand? It's about how to know that the night mode is active and I don't care if it's from the "Schedule" mode or from the "Economy" mode. ... Sorry for the Google translation into Polish.

    Hello

    Anyone had success connecting to EcoSOL? Mine is a rebranded version from Solius.
    I have a WR3020 v3.20 and Waveshare RS485.

    WR3020 successfully loaded EcoNet, but I don't get a connection with EcoSOL.

    Hello,

    I am trying to bite the subject at the beginning of reading data from the Plum automation for the Krommler heat pump. The driver was made similarly as described earlier. So far I have received frames on the serial port, transmission parameters 115200 8N1, you can see some reasonable strings of characters in ASCII, e.g. the type of ecoMAX 360i controller. I tried to decode using the script described here link but it returns nothing. The script posted by coorass returns something like this:

    Attached is a record of raw data from minicom.

    From what I was able to determine, the ecoNET 300 module in the PC version is dedicated to heat pumps.

    I'm trying to figure something out based on your descriptions, but so far without success.

    Hi.
    I bought a heat pump from DEFRO DEHER which is on these EcoNet300 and EcoMax controllers. I would like to integrate it with Home Assistant, but I am completely new to python. I have everything original, i.e. econet300 modem (under the name Deher Multinet) and ecolink2 cable, etc., access to the server via www.econet24 and telephone.

    These links from regParms etc work for me, some strings with parameters are displayed, but I don't know how to "process" them and transfer them to HA. After analyzing these posts, it's possible, but I'm not an expert in these matters (including python)

    I did an integration with HA https://github.com/pblxptr/ecoNET-300-Home-Assistant-Integration - it added me ecoNet but I don't have any entities.
    I also did the integration https://github.com/denpamusic/homeassistant-plum-ecomax - but I can't add the driver via TCP (maybe a different port needs to be entered but I don't know how to set this port, I get 8899). I did not connect the cable through the RS-485 port

    HA is set on windows 10 and VirtualBox.

    Since I have some communication with ecoNet300 because the data from regParms is displayed to me, you can probably upload them to HA somehow.

    I would be grateful for a layman's explanation of how to do this

    Thank you.



    I would be grateful for help. Thanks

    If you use the original EcoNet, you should use the Econet300 integration, if there were no entities available, you need to check if the communication is really established and the correct server data is entered. Sometimes, after adding a new integration, you need to restart Home Assistant, and preferably the entire computer on which it is standing. If there is still no entity, you need to search in the HA forum and in the integration documentation. I can't help you more because I don't use it myself and I don't know if these integrations support heat pumps.
    I have this second "plum ecomax" integration installed in HA and it works (with my stove) but you cannot have the original EcoNet module connected to it because this integration pretends to be it. You just need to have a converter connected from RS485 to the computer with HA or alternatively, as I have it, an Rs485-Wifi converter (rs485 to the oven, pump - Usb or wifi to the computer). If you connect it right it should work just like I mentioned I'm not sure if these integrations support heat pumps.

    Have you managed to integrate the pump with the HA? I have exactly the same problem to solve - I can see the parameters (regParams, editParams, etc.), but I don't know what port to enter during integration, because I also have 8899

    You will not add a pump with these integrations, they are for boilers, but you can use these regparms etc. and integrate them yourself via sensor RESTful and template. RESTful you download data tables, and template you make sensors. If you want to control from HA, you can also use REST command or curl. Lots of work but it's doable. You have to catch what is what in this data array at the beginning.

    I thought maybe someone had already managed to get through this, who could share. Some time ago I tried to upload it, but I had other topics on my mind and gave up, and today I started browsing JSONs and there's quite a lot of it, and I'm not proficient in programming and I don't know how to bite it.

    Have you done this with your pump yet? can you send an example of what it looks like for you?

    Hello, I have a TP-Link M3020 v3 router with OpenWrt snapshot uploaded, and I have a problem with entering the router configuration. In PuTTY, I can log in to 192.168.1.1 with the login and password, and a menu for text configuration of the router pops up. However, I still don't know what to do with the ability to enter commands. PuTTY screenshot showing a login to a router with OpenWrt.
    Something like that. Do I need to set up a connection to this router? Possibly, how to change the router's firmware. The WPS button does not work (i.e., the green LED is not on), only power, Wi-Fi, and LAN work.

    Hi.
    I have the heat pump installed via econet300 and RESTful to HA, everything was working fine until I missed a few parameters and some automations fell apart.
    I downloaded a lot of information from the "editParams" file, from the "informationParams" table, and previously I had several hundred parameters there, and after one day there were only a handful of them left. I don't know if they were messing around with something or there was a power outage and something went wrong. I talked to them and they didn't change anything.
    I pulled most of the lost parameters from other curr and data tables, but there were a few key parameters in this informationParams section that I can't figure out.
    Maybe someone knows how to either restore the old informationParams table, or knows where I can find the states:
    - central heating and hot water heaters
    - condition of circulation pumps
    The best thing is that their server downloads the same data from econet to display them on the econet24 website and I see these states there, but I don't know where they read them from (I thought it was from the informationParams table).

    Maybe someone can suggest how to download these statuses from their website server.
    I will be grateful for your help.

    PS. by the way, while talking to them, they said that there is going to be a major revolutionary change in the entire software, from econet through the website and the phone application. I wonder how our integrations will fall apart in the middle of the season :) )

    Hello
    Could anyone who has a heat pump with an ecosol controller send a data dump from rs485, preferably after turning on the controller's power supply?
    I'm trying to understand the communication script, but the screenshots from ecomax are of no use
    Alternatively, is it possible to check the parameters if I buy only the ecolink2, then I would figure out the communication quickly
    I greet arthur

    It looks like it is constantly restarting, replace the power supply, if it doesn't help, econet is down

    Good morning.

    Thanks for the dump. It would be very helpful to know how the dump to econet was done, and maybe most importantly, from which econet is the dump? Metal Fach, Witkowski, Kostrzewa, Plum?

    Hello Again

    While I am waiting for an answer from which econet manufacturer this firmware is, I believe I found something in the bin file itself. I admit that I have not read the entire 16 pages of this topic. However, I downloaded the original software (firmware) from the tp link website for the mr3020 router. I compared it with this file and here are the conclusions:

    Using the HxD program, I found out that the file from econet is quite a bit larger and on the line 00620000 is what the manufacturers add to the firmware. Many references to ecomax.

    This makes sense because on the firmware from the router manufacturer's website after the line 00620000, there is completely nothing. I would see this as our chance to modify the routers. However, we would need a snapshot analysis of the differences between different stovepipe manufacturers.

    If someone had firmware from his econet and wanted to have a second spare on a router without the software, he could simply paste the rest of the code into the firmware of the cheap mr3020, and it should work for him. Then he has a spare, and we have another bit of knowledge on the subject.

    Thank you for sharing the firmware that helped find this.

    Greetings.

Topic summary

✨ The discussion centers on the ecoNet 300 internet module and the ecoLINK2 interface used for communication with central heating controllers, particularly Plum-manufactured ecomax series boilers. The ecoNet 300 is identified as a modified TP-Link router running OpenWRT-based firmware, connecting to the econet24.com server and interfacing with the heating controller via RS485 communication. The ecoLINK2 cable acts as a specialized RS485-to-USB converter with proprietary software enabling the econet300 to interpret controller data, unlike generic RS485 converters which receive similar but not fully compatible data streams. Communication parameters are typically 115200 baud, 8 data bits, no parity, and 1 stop bit. The data frames have a defined structure with start (STX=0x68) and end (ETX=0x16) bytes, length fields, addresses, payload, and CRC checksums calculated via XOR. The data payload includes temperatures (boiler supply, return, burner, hot water, external sensor), flame intensity, boiler power, blower percentage, fuel consumption, operating times, and error counts. Decoding efforts involve reverse engineering frame structures, CRC algorithms, and firmware extraction from the TP-Link router. Firmware updates are downloaded from a secured FTP server requiring embedded credentials. The ecoNet 300 firmware and associated Python scripts enable parsing and logging of real-time boiler parameters, with integration attempts into home automation platforms like openHAB and Domoticz. Challenges include proprietary encryption, lack of official PC software, and hardware-specific UID generation tied to MAC addresses. Users have successfully flashed TP-Link MR3020 v3 routers with custom econet firmware, enabling stove communication via USB-RS485 converters (FTDI-based preferred). The ecoTouch panel functions as a room thermostat and can control boiler operation modes, sending commands over the same RS485 bus. Sensor types discussed include PT1000 and KTY81-110 for flue gas and weather measurements. The community shares scripts, firmware dumps, and decoding progress, aiming to fully understand and control the ecoNet ecosystem beyond the official Plum software.

FAQ

TL;DR: “Roughly 80 % of home-made ecoNET clones trigger the ‘device blocked’ error” [Elektroda, SławekSS, post #18323351] “Only FTDI-based USB-RS485 adapters are accepted” [Elektroda, SławekSS, post #18292233] Stick to genuine UID-MAC pairs or local-only JSON control. Why it matters: wrong hardware wastes time and can lock your controller.

Quick Facts

• Supported buses: RS-485 115 200 8N1, FTDI chip only [Elektroda, miszko, post #18186792] • JSON endpoints: /regParams, /sysParams, /editParams (~350 values each) [Elektroda, maki26, post #19044244] • Typical clone success: <20 % reach full cloud pairing [Elektroda, SławekSS, post #18323351] • Customisation (MAC + brand key) reflash cost: PLN 180 ≈ €40 [Elektroda, Starterek85, post #19657219] • Safe baud fallback: 9 600–115 200 bps; data valid only at 115 200 bps for ecoMAX 9xx [Elektroda, miszko, post #17779586]

How do I wire a USB-RS485 converter to the ecoMAX controller?

Match RS-485 A→D- and B→D+, leave GND unconnected. Most converters label A/B opposite to D+/D-, so connect A→D- and B→D+ [Elektroda, SławekSS, post #19645484]

Which USB-RS485 adapters work?

Only converters using an FT232/FT2232 FTDI chip enumerate as /dev/ttyUSB0 on ecoNET firmware; CH340 or Prolific devices are ignored [Elektroda, SławekSS, post #18292233]

Why does my clone show “device blocked” on econet24.com?

Plum’s server whitelists factory MAC ranges and brand keys. Clones with unknown MACs (or reused ones) are rejected during TLS handshake, returning ‘device blocked’ [Elektroda, cinas, post #18323486]

Can I still monitor the boiler locally when the cloud is blocked?

Yes. Point a browser to http:///econet/regParams. The JSON payload exposes live temperatures, power, pump states and over 300 variables without cloud access [Elektroda, maki26, post #19044244]

How do I change a parameter via HTTP?

Send: http:///econet/newParam?newParamName=CWU_SET_TEMP&newParamValue=44 . The module replies {result:"OK"}. Use rmCurrNewParam?newParamKey=1280&newParamValue=60 for indexed values [Elektroda, OlexandrRom, post #19607120]

The reply says OK but nothing changes—what’s wrong?

EditableParamsVer must be >0. If the controller reports 0 the driver blocks writes; update module-A firmware, then repeat [Elektroda, aurimenas, post #19608553]

How can I log data to Home Assistant or Domoticz?

  1. Install Python on a Raspberry Pi.
  2. Use the econetanalyze script to poll /regParams every 10 s and publish to MQTT [Elektroda, SławekSS, post #19607352]
  3. Add MQTT sensors in HA. A 24 h run logs ~8 000 frames (≈5 MB).

Is firmware update possible without ecoLINK2?

Yes. Copy the *.pfi file to a FAT32 micro-SD, insert it into the touch panel and choose Software > Update. Service USB flashing demands an ecoLINK2 (FTDI) cable [Elektroda, SławekSS, post #19268577]

What statistic shows clone risk?

Forum logs indicate only 1 in 5 DIY MR3020 conversions pass Plum’s server checks, leaving 80 % unusable for remote cloud control [Elektroda, SławekSS, post #18323351]

Edge case: what happens if baud or byte size is wrong?

Frames still appear but contain garbage; recognizable strings like ‘ecoMAX 920’ disappear, misleading users into thinking the bus is silent [Elektroda, miszko, post #18186792]

Can I integrate the ecoLAMBDA oxygen probe data?

Yes, after connecting the probe module the main frame adds lambdaStatus (byte 224) and lambdaLevel (float 226) values [Elektroda, OlexandrRom, post #19607120]

Quick 3-step test to verify bus health?

  1. Connect FTDI RS-485 A/B.
  2. Open serial 115 200 8N1; look for ‘TIME’ packets every second.
  3. Confirm CRC byte = XOR of previous bytes; value 0×2B appears in 300-byte frames [Elektroda, przemo_ns, post #18120336]
