Heatmiser App Pairing / Discovery Failure

Thermostat cannot be discovered or added in the Heatmiser app

Possible Causes

Phone not on same network, VPN enabled on phone, Router isolation of wireless clients, Thermostat not in pairing mode

Safety first: No electrical work required.

Steps:

Ensure your smartphone is connected to the same 2.4 GHz Wi‑Fi network as the thermostat or NeoHub.
Disable VPNs or mobile data during pairing.
On the thermostat, initiate pairing mode as per the manual (often via a Wi‑Fi or cloud menu option).
Check router settings for client isolation or AP isolation and disable them so devices can see each other.
Restart the router, NeoHub (if used), and thermostat, then retry discovery.
