@w1ll1am23 , completely understand the crazy busy. If I knew how to develop I would, but certainly will humbly and patiently wait. That being said, I would be happy to beta test if that would be helpful…
With Plum being a completely different thing from the original Rheem integration. I wouldn’t say it was abandoned. I would say it was never started. Without having a device it’s going to be very difficult for me to build anything for it and even if I could get something built maintaining it would be impossible.
