[OpenTRV-interest] Frequent non-communication periods between hub and its valve

Two things commonly cause problems:
1) Transmitter too close to receiver seems to deafen it (FHT8V or OpenTRV in listen mode). Minimum distance of ~2m seems to be safe.
2) Batteries getting low on FHT8V.
Sorry that you’re having this trouble!
