I know - it may be a strange request - I completely (almost) moved from OH to HA but in my house I’ve got a “Hermes Electronic WR3223” ventilation controller which I was able to control from OH because there is an existing binding:
It is on GitHub available, please refer to these links:
Unfortunately I’m not able to create integrations in HA - this is why I’m looking for a dev who could create this for me and the community. Surely this could be rewarded.
Maybe there is a brave soul out there who could help.
If this is not the right place to ask for help (in this community), please let me know or delete this topic.
PS: currently I’m using the custom component “openHAB integration” by kubawolanin ! Thanks man!
