Bosch CLC8001i

[roboticsalign]

Dear all,

Thanks for this great project.

I am trying to get a Bosch CLC8001i connected, but the board seems to be different:

CN70 has +5V and GND on pins 0 and 7 and can power the esp. But do you have a recommendation, where RX and TX could be located or how I could search them?

That seems to be a different version of the board, but as far as I know, the CL8000 series also uses the G10 CL-2. Looking at the third-party module from WiHeat on this page the pin assignment appears to match. Please let me know if this is the case so I can include it in the README. The init log might also provide some insight, especially for identifying unknown bytes, since this is a different version. If everything matches, please provide the init log.

Edit:

CN70 seems to be the wrong connector; it should be CN13A

thanks. I'll give it a try, when I'll get the source code compiled...

[roboticsalign]

It seems, that I have a different one. The Wifi module is connected to BCN13 and seems to have a different configuration. Pin 1 seems to be GND and Pin 4 +5V. But the other Pins do not provide data on RX at ESP side. Do you have a recommendation, how to analyze the pins?

[roboticsalign]

Well, I just had a bad connection at PIN3... So I can confirm, that it connects with:
Pin1 (red): GND
Pin2: RX
Pin3: TX
Pin4: 5V

The behavior is different to my Buderus device with a CN13A pin. I'll do some more research on that and post the init sequence later.

I'll get the following init data. Esp is not recognizing, that it is switched off, but the switch command seems to work. Than I can start heating again. Plasmacluster is not recognized by esp. I cannot check, if the command is working.

Thanks for the data. The current version in the refector branch should fix some of the issues with the 8001i.
