To control the Combi heater and Heat pump via Home Assistant, I must reverse engineer the communications protocol between the LCD displays and the units. This is more my personal notes. Arduino like Microcontroller and a LIN bus chip 2. Heat Pump Tuya board + RS485 (TP8485E), likely running ModBus The Combi does have a…

The big downside for me is lack of native integration with Home Assistant for automation, power tracking, etc, however, it seems there are…

I work remotely, so communication is critical. I’ve decided on a multi-layer connectivity setup with WAN failover/load balancing. Starlink I don’t need to explain this one, as starlink is widely known, but I went with a Standard dish as I get 300Mbps and more reliable connectivity vs the mini dish as averages 100Mbps. I put…
