Thermostat does not respond to commands from the Mysa app, but local control works.

Safety first: No high-voltage work is required.

Steps to troubleshoot:

• Check device status: In the Mysa app, see if the thermostat shows as online. If offline, resolve Wi‑Fi issues first.
• Log out/in: Sign out of the Mysa app and sign back in to refresh tokens.
• Re-add device: Remove the thermostat from your Mysa account and add it again using the setup process.

If local control is fine but remote control never works even on a known-good network, the cloud communication stack on the thermostat may be faulty. Replace the thermostat.
