1. Q: Can I control a Wi-Fi TRV remotely when I’m away from home?
A: Yes, remote control is a core feature. As long as the TRV is connected to Wi-Fi and your phone has internet, you can adjust temperature, set schedules, or turn heating on/off via the app from anywhere.
2. Q: Why is my Wi-Fi TRV losing connection to the network frequently?
A: Possible causes include weak Wi-Fi signal (move the router closer or use a Wi-Fi extender), incorrect network credentials, or router compatibility issues. Reset the TRV, re-enter Wi-Fi details, and ensure your router supports 2.4GHz (most Wi-Fi TRVs don’t work with 5GHz alone).
