Why Do Smart Home Devices Stop Working Suddenly?

Smart home devices often stop working due to lost Wi‑Fi, a tripped breaker, or a power surge that disrupts electronics. App or account changes and firmware updates can also disconnect thermostats, lighting controls, or security systems.

Quick checks:

  • Power cycle the device and your router.
  • Verify the breaker or subpanel circuit is on.
  • Confirm app login and Wi‑Fi credentials.
  • Install pending firmware updates.
  • After surges, consider whole‑home surge protection at the main panel to protect smart gear.

In Denver homes, we also assess wiring, panel capacity, and smart‑thermostat compatibility.
