2-Wire Heat Only Thermostat

[Locutus]

If anyone is interested in following my saga on keeping the Zen on the Zigbee network, I created a new thread here:

Zen Thermostat keeps dropping off the network

I recently setup a Zen Zigbee Thermostat to control my Gas Fireplace on / off switch. Setup was pretty straightforward, it paired quickly using the built-in HE Zen driver. But after a few hours of operation it drops off the network. At first I thought the distance to the hub was the issue, so I placed a zigbee wall outlet 1 metre away to act as a repeater, but it still dropped off. I took a look at the Zigbee logs while it was running and the LastHopLqi was always over 200 and the RSSI was usual…

I am now fearing that a battery powered thermotat simply won't stay on a Zigbee network.
