Typical range is 20–40 metres indoors, but placement and interference sources make a big difference.
Optimal placement
- Place RF-HUB elevated — preferably 1.5–2 m up.
- Avoid direct contact with metal (fridges, radiators, large appliances).
- Keep at least 30 cm from your Wi-Fi router.
- Place centrally in the home — not in a corner.
Common interference sources
- USB 3.0 ports (can generate 433 MHz noise) — use USB 2.0 if possible.
- Wireless video transmitters (some baby monitors).
- Faulty power adapters / cheap LED drivers.
Larger homes
Add an extra RF-HUB — for example one on the ground floor and one upstairs. They are coordinated via Home Assistant or Homey as the "glue".
