Verified July 2026
A cheap hubless Wi-Fi wall stat for combi boilers and hydronic underfloor heating that the meross_lan HACS integration controls over plain local HTTP — no cloud, no subscription. It replaces a wired programmable stat (volt-free contact), so check you have a neutral at the backbox; it won't do electric heating or hot-water channels.
