Amazon Smart Thermostat Intermittent Network Connectivity

Thermostat loses Wi‑Fi connection intermittently but HVAC still works

Possible Causes

Weak Wi‑Fi signal, Router channel congestion, Interference from other 2.4 GHz devices, Overloaded router

Note: HVAC control usually continues locally even when cloud is offline.

Improve signal: Move the router closer to the thermostat or add a Wi‑Fi extender/mesh node.
Change Wi‑Fi channel: Log into your router and select a less congested 2.4 GHz channel (1, 6, or 11).
Reduce interference: Keep the router away from microwaves, cordless phone bases, and thick metal objects.
Router reboot schedule: Periodically reboot the router or update its firmware to improve stability.
