When I first connected my T6 Pro z-wave I had batteries in it for reasons I don't recall. I didn't realize until later that if you had batteries in it when you paired it, the power mode would stay as battery even if you removed the batteries.
I tried excluding the thermostat, removing the batteries, checking that the Power Mode on the thermostat read as 24 VAC. But when I re-paired it, it still thinks it's on battery power.
I'm currently using the Generic Z-Wave Plus driver, but I've tried both Advanced T6 drivers and no change.
Have you tried switching the driver to plain "Device" and then using its options to clear current/all states, and the switch back to normal driver?
That battery entry may just be a leftover artifact, but I have no experience with this device so I'm not certain. The "Device" trick won't hurt anything though, so perhaps worth a shot.
ETA -- you should hit "Configure" anytime you change drivers.
I have several t6 zwave t-stats. Is it possible that your thermostat did not have mains power while you were joining it to your ZW network. Sounds trivial I know but I had a problem on one of my furnaces where a moisture detector shut off AC power to the furnace and I didnt realize it (even though the circuit was live at the breaker box), and as a result the tstat kept joining as a battery powered end point device rather than a mains powered zwave node. Once I found the problem I was was able to do a zwave reset on the tstat and rejoin it as a node.
BTW...the equipment status page on the t-stat screen will confirm whether it is joined as a ZW node or as an end point device. Provides some ground truth to check against what the drivers are telling you.
I hadn't heard of this before. Tried it, and the "powersource: battery" state went away entirely. I could tell that the Hub was holding on to that old setting somehow, but didn't know how to get rid of it. Thanks!
I learned something new today. Thank you!
In case anyone else has this same issue later, the problem seems to be with the Advanced Honeywell T6 Pro Thermostat driver. I played around with changing drivers, and the "powerSource: battery" state only showed up after I changed to the Advanced driver. And it still says it's on battery. Must be an issue with that driver.
I'm now in the habit of doing that "Device" trick anytime I switch drivers -- it just helps ensure I'm working with a clean slate when I hit "Configure" on the new driver.
I was going to cross-post this to the Advanced driver thread. I went and re-read the last couple dozen posts there, and apparently the fix is to add or remove the batteries, plug it back in to the wall, then remove or add the batteries again. Somehow that clears the memory.
Driver only gets a "battery report" when the charge level drops below a certain point or when the thermostat switches from mains to battery or battery to mains. If the hub isn't listening when the battery report comes through (due to a reboot or hub losing power) then status change may get missed - sometimes hitting Configure will cause the thermostat to send an updated battery report.
