Insteon
Thermostat 2441TH
The Insteon Thermostat (2441TH) is a hardwired smart thermostat that Home Assistant reads and controls locally, with setpoints, heat, cool, and fan modes plus temperature and humidity reporting.
A hardwired thermostat powered from the HVAC system’s 24 VAC R/C circuit, so a C (common) wire is required; it does not connect to a mains neutral. Not compatible with heat-pump systems. It exposes setpoints, heat, cool, auto, and fan control plus temperature and humidity to Home Assistant. The 2441TH is RF-only and needs a dual-band Insteon device within range to reach the Hub or PLM. Controlled locally through an Insteon Hub or PLM with no cloud, after all-link linking. This model is discontinued and secondary-market only; do not confuse it with the 2441ZTH battery wireless companion thermostat. The revived Insteon does not currently sell a thermostat.
