Most of our IQ2+ z-wave network is working fine. The house came with the Qolsys panel, but since it was locked, I ordered a new one from Surety – it works fine. I added the existing house devices (Kwikset 888 and Eaton RF9601) and ordered an additional one of each… The devices all added fine and work fine when sending status to the panel – the panel can interrogate their status immediately and reports all manually induced changes.
However, when I try and control the devices with the panel (to lock/unlock the door or turn the lights on/off), about half the time the panel hangs for a minute or two – sometimes it works, sometimes it does not. It is as if there is a network issue resulting in retries and retransmissions, or some such thing. The whole house is maybe 50 feet long, and the panel is right in the middle – even the closest device (10 feet away) behaves the same. In addition there is a Honeywell T6 Pro z-wave thermostat on the network.
Any suggestions what I can try to get this to be more reliable? I repositioned the antenna and turned off bluetooth on the Qolsys since we are not using it, but that had no effect.
