Thermostat loses pairing with Ideal smart TRVs or room sensors

Safety first: No mains work required.

Steps:

• 1. Replace accessory batteries: Fit new batteries in TRVs or wireless sensors.
• 2. Re‑pair devices: Put each accessory into pairing mode and add it again via the thermostat or app.
• 3. Improve RF path: Move the thermostat or add a repeater (if supported) to reduce distance and obstacles.
• 4. Update firmware: Ensure both thermostat and accessories run the latest firmware.
