I have encountered some signal problems with my FP300 sensor because my G3 camera hub was far away. To improve the signal, I installed a T2 Zigbee module halfway between the hub and the sensor. By doing this, I have improved the signal and got the sensor working correctly. The key here is that the T2 works as a repeater and has a direct current connection.

@matera87 Nice workaround—and you’re absolutely on the right track conceptually. Mains-powered Zigbee devices are ideal “midpoints” because they can act as repeaters/routers and help bridge that 7–10 m range where battery sensors can start getting flaky. You can extend your network range beyond 7–10 m by using devices like Aqara Smart Plugs, Aqara bulbs, Aqara relays (with neutral), or Aqara Wall Switches (with neutral), since they’re powered by the home’s electricity and act as repeaters.
A couple of practical tips that usually help make the improvement stick:
- Placement rules of thumb: keep the single-hop distance reasonable (about ≤10 m, ideally no more than 2 walls) and spread sub-devices more evenly across the space.
- If a sensor doesn’t “choose” the repeater reliably: a common trick is to force a re-route by temporarily powering off the hub, then re-pairing/refreshing the accessory connection (triple-press reset on the accessory), and powering the hub back on.
If you’re able, it’d be cool to hear what your before/after distance and wall count looked like—those details really help others replicate the same fix.

I will try and add some more devices and see how it improves.
I currently have 3-4 walls between Hub and sensor so i have the Relay with neutral in between but still with 1-2 walls in-between.

@matera87 Yep, that plan makes sense. With Zigbee, the big win is keeping each single hop reasonable—ideally within ~7–10 m and no more than 2 walls between the hub → repeater → sensor. That’s exactly why adding a mains-powered “midpoint” (like your neutral relay / T2 module) tends to stabilize things.

Given you started at 3–4 walls hub-to-sensor, adding another repeater/router so each hop stays at ≤2 walls is usually the next practical step. Try to distribute powered Zigbee devices a bit more evenly so the sensor has multiple solid routes back, rather than one “long jump.” This information comes from community discussions and user experience summaries and may vary by environment.

If you run into a case where the sensor doesn’t seem to “stick” to the new repeater path, you can also use the common reroute trick: add everything to the hub first, power the hub off briefly, triple-press reset on the accessory you want to reroute, then power the hub back on.

Out of curiosity—roughly how many meters is each leg (hub→relay and relay→sensor)? That helps sanity-check whether distance or wall material is the bigger culprit.
