WPC-07-Cool

[m2teusz]

Hi, I have a WPC-07 pump with the following modules: WPM3i, FES, FEK, MFG, unfortunately ESPHome (2023.8.2) does not read most of the sensors. Is it possible to adapt the code to my pump? I tested the code from "github.com/roberreiter/StiebelEltron-heatpump-over-esphome-can-bus" and here most of the sensors work but the control option is missing. I used ESP-WROOM-32 + MCP2515 for communication. Attached is the log of your code as well as the code of colleague roberreiter.

I am sailing this week, I'll have a look when I am back. Have you adapted the CAN IDs in the esphome sketch and heatpump.h as described in the readme?

So I tried but with poor results, in addition, some addresses overlap and readings are missing.

hi,

I want to migrate from roberreiters stuff, too (tecalor TTF 07-cool, which is the same as the Stiebel eltron WPC-07cool) .

I did not have much time, yet for testing. Only a few values (like temperatures) were working.

@bullitt186 @m2teusz are you familiar with discord? We could join forces while debugging

Sounds good! I think one major feature to add would be some kind of "autoconfig", maybe by having lists of potential can member IDs and scanning which ones respond to e.g. a request of the sw version. I think this is one of the biggest hurdles for anybody setting this up (same for robreiters version) I am sailing this week so I cannot do much this week

@bullitt186 very cool idea! If testing is needed I will be happy to help when I return from vacation.
