@mcweis I bought the same board you linked, but I still get the same issue. Could you share your yaml-File? Maybe also which version of ESPHome you are using.
I’m using version 2023.10.1 of ESPhome
And this is my yaml-file. I hope it works for you, as I’ve made a little change, as I have an EWT. But it also worked for me with the original file from schmurgel

I’ve first connected the board to ESPhome and then pasted the code into the existing yaml-file
@mcweis THX for the share of the YAML! It works well. I still have a question about this, taxes don’t work yet. Is that because of this status:
If yes, what must be done to get it activ?
i just found in the logs:
Must the panel disconnected?
@stekolos-dev What did you change? I still get the same error. The only difference is that in my yaml is not a OTA passwort set as this seems to be deprecated.
I post the YAML and changed the API and OTA passwort. I thing the trick for me was do flash and only wait until the ESP was connecting to wireless lan. But i tryed it several times, before it works now.
From where do I get the OTA passwort? Can I define it freely in the yaml or does it needs to be stored somewhere?
This steps helped me:
First install an ESP32 as new device (direct in HA) and flash this basic setup to the ESP.
→ Install
After that was working fine. I copied from this part from step one
Enable Home Assistant API
api:
encryption:
key: “from the basic setup - step 1”
ota:
password: “from the basic setup - step 1”
i change only this from the original YAML from @mcweis
That works for me.
Thx for your response…I tried in in so many different ways . Its working finde until I add the files from the yaml-File. Then everything complies, flashing works but the device seems not to start.
The last try I had was to build only the bin-File with ESPHome and do the flashing via https://web.esphome.io/ and USB. This gives some new info. In the logs I can see after flashing:

mode:DIO, clock div:2
load:0x3fff0030,len:1184
Terminal disconnected: BreakError: Break received
When I flash it with basic setup booting seems to work without problems.
Same is thing. After flash and startup i must wait abaout 2-3 minutes. But than it works.
Yes, if you want to controll it by home assistant you have to detach the “Bedienteil”
Look at the pictures in github
If you’re sure you can build it back if Iit don’t works, give it a try. My heating looks like the pictures at github. I have a plug, wich I pulled out and that was it.
I have detached the display “Bedienteil” now it works. But think i must do some fine tunings in the settings, because the “Zusatzheizung” is starting in every mod. Also the option “Zusatzheizung” and “Wärmepumpe” could not be setup. For info, we have a “Häusliche Feuerstätte” and a “Erdwärmertauscher”. Our house is from 2006.
Our hous is from 2015 and we’ve also a “Erdwärmetauscher” perhaps the orders to manage your heating are diffrent with the model you own.
Do you know were i cold change the heating order? I am wondering, that it works, because in a document i got from Schwörer it is not possible to set the heating mode 
. But it works.
The mode is set in the file wr3223_modeValueDecoder.h, but I don’t know, how it works.
Also, if I look at your picture, it seems, that you only can read the mode and not write=set it?
I am very surprised at the manufacturer’s information from Schwörer. I can really control something with the currently code. However, the compessor always starts, I actually want to avoid that. But with Schwörer I am not surprised for a long time anyway. Our original Bedin Panel is exactly 3m away from the Häusslichen fireplace. This leads to the fact that the set room temperature leads to the fact that the bypass opens and all rooms get cold. Finally, finally ventilate when manually. That is exactly what I want to improve with the circuit.
I think the control and the code underlying here will certainly help me. And with the help of the community we fix it 
Hello everybody,
