I have just had an Ideal Vogue boiler installed in my home complete with the Halo Thermostat. I can see from the controller that it is a Zigbee device so I’m currently looking for a way to set this up on my Home Assistant myself
I too have an Ideal boiler with Zigbee & Wifi and I’d love to know what kind of roadblocks you encountered and whether you were able to get it into HA.
