I have an OG Google Nest thermostat with “HeatLink” heating controls. Got it free when I signed up for the electricity supply when we moved in 10 years ago, works fine, the thermostat isn’t ugly, all good. Until later this year when Google will stop supporting it and I won’t be able to control it remotely or set schedules any more. I’ll be able to turn the heating on and off manually, that’s it.
So I’ve been looking at alternatives, there’s a few out there, Drayton Wiser stuff seems to be the best option for integrating with #HomeAssistant, a wall panel and wireless thermostat is around €200, and I can add on thermostatic radiator valves for zoned heating.
But then I realised that all the HeatLink thing I have now does is toggle the power to the boiler when it gets a command wirelessly… it’s a smart relay. Like a #Shelly smart relay. I can literally swap it out for a Shelly relay and use Home Assistant to turn the boiler on and off. I think I have one in a drawer somewhere, and if not they’re like €25.
