MINI-ZBRBS Loosing Connection

Hello all

When the MINI-ZBRBS was release I bought a few to replace my DUALR3.

But I have a big issue with the MINI-ZBRBS. I set them up, connect them to the iHost, and they work for 1 or 2 days. And then they are gone. The only way to fix this is to turn off the power and do the reconnection process again.

What acould be the problem? I have the exact same wiring that I had with the DualR3, MY Zigbee network is strong an other Zigbee devices near the MINI-ZBRBS work perfect

Thx for your help
