The current Heatmiser climate component supports devices which connect over RS232/IP. Later devices supporting Wifi are not supported by that component. Until recently custom component https://github.com/daveNewcastle/Heatmiser-WIFI based on the native heatmiser component did work fine. Since change #23899 this custom component has not worked.
Can you integrate the above functionality for Wifi thermostats into the existing heatmiser component?
