In this video we take a look at the Heatmiser neoHub Mini OT smart thermostat kit which could be one of the most flexible smart thermostats on the market. Not only does it support dual heating zones and Opentherm, it also supports an official, fully documented Local API for integration with other smart home systems. In my situation, I have integrated this with my NodeRED & HomeAssistant based smart home system to allow me to set home/away on the heating system based on the arm state of my Texecom alarm system.
