It appears to be ok.
In that case, you are not connecting to the solar controller.
Check on the board (along the paths) to which pins A and B are actually connected, if you are sure to the middle two of this rj-12
I have uploaded the soft and everything is getting up. I need those solar collector files to be uploaded to the /www/econet folder. I deduce that they are in this bin file, however I cannot extract it.
@ppsirius just opened the file in 7zip and the files are immediately available, but for the lazy I am uploading a 'zip' file excluding the 'www' content for solars
Does this ecosol firmware have some kind of lock-in? I'm trying to upload this bot under solar collectors, trying recovery.bin, tp_recovery.bin, however nothing is uploading from TFTP server. I hold WPS and the router starts flashing, also set static IP to 192.168.0.66, however I am unable to upload firmware under the collectors. Do you guys have any ideas on how to get this working?
I have uploaded ecosol and now I am unable to restore OpenWrt. It pings 192.168.0.66, but after firing up tftpd64 and holding the WPS button nothing happens. Has anyone had any success uploading OpenWrt on ecosol?
IP address 192.168.0.225
The *.tftp-recovery.bin file is available in the root and renamed as tp_recovery.bin
Connected to the mr3020v3 via a wired connection
Install OpenWrt
Power off the mr3020v3
Hold down the 'reset' button - this is adjacent to the row of lights on the top panel
Apply USB power to the mr3020v3 while holding the reset button
After 20-30 seconds the upload will be complete, release the reset button
The OpenWrt image will now be loaded on the device. By default wireless will be disabled. The system will be available on its wired interface on 192.168.1.1.
Once you have openwrt, update it by selecting the .bin file.
It will scream that you have the wrong file etc. but confirm that you still want to do the update
It worked (it is reading the UID from the controller)! Thanks a lot for your help! I'm just wondering how I can read more sensors, because so far I don't have any useful information there. I'm mainly interested in the information from the DHW tank, which is available on the controller. I should add that I am connecting it to the ecosol 500 solar collector controller (I have swapped the files in the www folder).
Hello
I have a Lazar module (MR3020) and still have the software update option available. I have one chance to capture this package. Any suggestions on how to figure this out? In theory I will use wireshark and some router with port mirroring or if I manage to get a TAP network adapter. I'm just wondering if I can then get the file from wireshark, or more like the address where the update is downloaded from. Interested please help Regards
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.
