Yet another Stiebel Eltron Heating Pump newbee entusiast with a WPL 18 E and esphome

ESPHome
1

Hello,

I am new in the wonderfull world of German heating pump.
As a former system engineer for Nixdorf/Siemens in the last century, I am able to understand some German technical words.

I just bought a house that had a heat pump installed in 2019.
this is a WPL 18 E
there is a WPM 2 (where I Connected X15 H and L to the mcp2515) (do I need a ground or + or - ? ) the ESP is running on a battery until the solution works.
there is a SBP200E and a SBB302WPL and outside there is the rest.
No schematic, no explanations, just “demerden sie sich”

I even don’t know if my HW is running
and how to get the addresses of my config…
Up to now, I just powered down and up my Heating Pump after plugging the MCP2515.on the can-bus

help !!!

Well.after one week or testings, I could get something that seem to start working.

an esp32 and a MCP2515 spi canbus adapter.

while sniffing the bus I could get some addresses:

as you can see, all about electricity consumption is completely wrong.
the outside temperature is one degree below the value writed on the WMW2 display, but seems fine,
only the source temperature is completely crasy.

by the way ECS stand for the french acronym “Eau Chaude Sanitaire” witch means domestic hot water or warm water in our case.
