Good news and bad news: the bad news is that I hardly have the time anymore to work on my side projects, which includes the Remeha Home app for Homey. The good news is that Homey have reached out and are making this an official app, supported by their own developers and the supplier. In this process, they will fork my code repository and I’ll ask them to have a look at the existing backlog items, which includes the cooling mode feature. Another benefit is hopefully official support from the supplier for their API (currently it’s piggybacking on the un-official API they use for their own Remeha Home mobile app).
So hopefully some updates for this app in the near future!
