I'm in the same position. I have Daikin Altherma 3 R F (EHVZ08S23DA9W7) and the X10A is already in use. I have tried now 2 different USB to TTL modules....

Thanks. Connecting GND did the trick. Here are some files, do they make any sense (I'm not sure what settings I should be using)? Would love to use this project....

Thank you @raomin for taking time in this, I appreciate it. I had problems with other USB-to-TTL to output anything but I found my old Arduino and used that instead....

Here are the new files. [pin3.txt](https://github.com/raomin/ESPAltherma/files/6454974/pin3.txt) [pin2.txt](https://github.com/raomin/ESPAltherma/files/6454975/pin2.txt) These timestamps may be off by a second or two. There's no really indicator when the setting is applied and it takes a...

[2 - pin2.txt](https://github.com/raomin/ESPAltherma/files/6455117/2.-.pin2.txt) [2 - pin3.txt](https://github.com/raomin/ESPAltherma/files/6455118/2.-.pin3.txt) [1 - pin3.txt](https://github.com/raomin/ESPAltherma/files/6455119/1.-.pin3.txt) [1 - pin2.txt](https://github.com/raomin/ESPAltherma/files/6455120/1.-.pin2.txt) I forgot how I wired up last time so here are both cases. I actually might have changed...

[3 - pin2.txt](https://github.com/raomin/ESPAltherma/files/6455216/3.-.pin2.txt) [3 - pin3.txt](https://github.com/raomin/ESPAltherma/files/6455217/3.-.pin3.txt) Here is new set of files. So around 00.48.50 there was following values in the sensors menu: - Outdoor temp: 14C - Tank temperature:...

Hello. Sorry, I've been really busy. Yes I had USB-to-TTL module and Arduino hooked. I have now switched to ESP32 and wrote [first version of program](https://gist.github.com/kaskii/33861e7e089e91c748f000a7756cfc2b) to capture data from...

Ok, I updated the serial settings to SERIAL_8E1 and now I think [the output](https://gist.github.com/kaskii/2c1ee3ecad52950ad363fcae81b4621b) makes more sense. I tried to raise main zone temp at 31-36 sec and lower it...

I don't know if your unit stores R9T and R10T data in same place as some other units may. You could try other definition files and see if you get...
