Internet module ecoNet 300 and ecoLINK2

jamrjan 197922 688
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]

    These sys, reg, edit only return the values it will read from the driver. They can be used to integrate with HA or domoticz systems or anything else that supports MQTT. It is enough to create a script such as Python which reads them and sends them to MQTT.

    Colleagues, I have EcoNet original + usb to RS485 converter.
    I don't have D + and D- on the converter but A, B and -. What to connect to?
    In the boiler controller, RJ11 socket, which, according to the plum instructions, must be used through a splitter to connect the ecolink via rj11.
    However, I can also see free connectors for the post-defeat thermostat on the controller and one more on the "power supply".
    Can I just plug the converter into any free D + and D-?

    Regards.

    I connected, the diode on the converter is blinking, so there is some communication. However, the econet communication light with the controller does not light up, and the boiler controller does not see anything new in its menu. You probably need to make a cable for RJ11 as instructed by the user manual.

    Some boiler manufacturers have software designed for themselves, the so-called customization.
    For example, Kostrzewa, Kipi, Witkowski, etc. Only econets, purchased from these producers, will work with these boilers, the original pluma will not work.

    What is the boiler (manufacturer)?

    They told me on the website that the econet is bought for the burner in the boiler, I have a setlans stove with the plum ecomax 920P1-K controller and the burner is boiling, so I have to buy econet300 when it is boiling.
    By the way, does anyone have a batch of econeta300 just under the boil?

    This converter from the photo is on the CH340 chip. Econet has no drivers for it. Ecolink2 is based on the FTDI chip (https://ftdichip.com/) and only works properly with this.
    I don't know about EcoUpdater, but first you need to upload the correct drivers to the computer.
    In general, look for a converter based on a FTDI chip.

    The address is public to my knowledge. I check it with the "What is my IP" method by typing in the browser. This address matches and is the same on a few other devices. However, this does not match the router's assigned IP address. The router comes with a modem and a Virgin Mobile SIM card.

    If you have a router with a SIM card, then if you have not purchased a public IP address from your operator, you do not have a public address.
    The public address can be either static or dynamic. For the latter, you also need a dynamic DNS server, e.g. no-ip.com.

    I want to start ddns later. First, I want to get a connection, at least once, because the IP is dynamically allocated. Every time the router boots up, it is different. Until the knock, I do not reset the router, IP can be treated statically. Does the screen explain that it is a public IP after all?

    What this page displays has nothing to do with what you want to achieve. It also displays the public address to me, but what if the router does not "bridge" the wan address with the provider's public address. You need to set up a private VPN router on the router and you will receive data for it from the internet provider after purchasing a dynamic or permanent public address.

    For interested users of Kostrzewy stoves, I can provide a program for reading and changing the parameters of the furnace. You do not need to have EcoNet or its "replacement", the only condition is a computer with Linux or, in my case, a Raspberry with Rasbian, which acts as an intermediary device in communication with the stove and is a gateway for external connection and an RS485 / USB converter. The connection is made via VNC.

Topic summary

✨ Discussion focused on the ecoNet 300 / ecoLINK2 ecosystem for Plum boiler controllers and how the internet module communicates with the furnace controller over RS485. The module was identified as a modified TP-Link router running custom firmware, with ecoLINK2 acting as more than a simple USB-to-RS485 converter because the controller only works when connected through the original ecoLINK2 chain. Participants intercepted and decoded the RS485 traffic, determined the frame format, CRC method, and serial settings, and mapped many boiler parameters such as temperatures, flame, blower, power, fuel usage, operating times, and ignition counts. Later posts showed that the ecoNet firmware could be extracted from a router image, that the web backend uses scripts and a parser for the controller data, and that the system can be adapted to home automation platforms like Domoticz and RRD. The thread also covered firmware update files, FTP/update access, MAC-based authorization, and hardware compatibility of TP-Link MR3020/OpenWRT-based replacements.

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?
