Compare this figure to other, much lower, Rx values in the list. Most radar sensors (a.k.a. mmWave) use wifi as communication protocol because of the constant flow of event updates. Zigbee was never designed for that.

Also mind possible interference by 2.4GHz wifi signals > [@Advanced Zigbee Troubleshooting on Homey](https://community.homey.app/t/advanced-zigbee-troubleshooting-on-homey/115930/18): > > So ive updated my SHS to 12.12 and overnight my zigbee is dead. It started with my Tuya brand devices but now i cant add any zigbee devices either. I have snapshots of pre update but on boot it brings back 12.12. I did disconnect the ethernet during boot but this didnt really solve the issue! These are the messages im getting in the shs log and when i try to use a device i get a timeout message and when i try to add a device i get an unable to connect. I suspect the bridge may be faulty but … --- _[View the full topic](https://community.homey.app/t/tuya-zigbee-communication-issues/152331)._
