A few months back I swapped from using ZHA & ZBT-1 to zigbee2mqtt & ZBT-2 and I’ve noticed a large increase in battery use, particularly with one specific device - an IKEA Praktlysing Blind. Prior to the swap over the battery was lasting roughly a year - since the swapover, it’s now lasting only 1 month. Here’s the battery history:
Swapped over to ZBT-2 and Z2M in mid-December (yellow-line I added on graph), and as you can see, since then the battery life has been terrible.
Things that are the same:
The rest of the hardware setup
Position of controller
Position of Blind and devices around the blind
No new automations that would activate it more
Blind is still connected via same router device next to it
Most of my battery devices are z-wave so it’s hard to be certain; a couple of others appear as though they’ve slightly increased battery usage, but nothing like this IKEA blind.
Is this something I’ve mis-configured / a known issue with these devices / a dying battery?
Would appreciate any suggestions for figuring this out (and ideally fixing it).
I've noticed that too. In my case, only the Eurotronics thermostats are affected. Or rather, after two months, those are the only ones I've been able to identify so far.
before: zha + conbee2 = 1y battery life
now: zha + zbt-2 = lithium energizer I bought one month before upgrading, all died after one month zbt-2 usage. then I think the expensive lithium are faulty and i switched to the Duracell 200%. after 2 weeks they are all between 20%-60%.
nothing changed after upgrade and winter is over. The thermostats don't have much to do.
I can't keep changing the batteries in four thermostats every few weeks. It's getting expensive and annoying.
Solution 1: Softwarefix. Is this a known issue?
Solution 2: Which thermostats don't have this problem? Danfoss?
Solution 3: move to another zigbee coordinator
ChatGPT told me there's an issue with the thermostats. They're communicating more than necessary. In the end, I don't know what to do about it or how to fix it.
