Finally found this thread, hoping for a simple solution for my issue: All six devices show wrong battery levels, all different but specific for the individual devices (just swap the battery packages and you will get 3% for batteries that showed 11% in another one, while 11% are shown on the other device for the batteries that were rated 3% originally). Removing six devices, adding them again, and re-doing the programming will cost me a day‘s work. So did somebody already successfully try the solution proposal? I‘m close to sending the devices back and buying Eve watering devices with Thread support instead, to be honest. I would need some positive news to remain a loyal customer which doesn’t write furious Amazon one-star reviews. Fixing the firmware would do the trick, for example.
