On a zigbee aqara vibration sensor I changed the battery alarm threshold from 20% to 5%. (advanced parameters) Battery level currently oscillates between 22 and 18% and I get the alarms each time the value goes bellow or over 20%. Why ? ---

Did you change the alarm threshold while keeping the device awake? Sensors sleep most of the time and I don’t think that Homey queues up commands for devices that are asleep (so when you set the threshold while it was sleeping Homey may _think_ it was updated when, in fact, it wasn’t). To keep the device awake, short-press the pairing button once every few seconds. ---

No, the device was not awake when I changed the value. I thought the alarm was a pure Homey threshold… I’ll try that tomorrow. Thanks. ---

> [@Remi\_J](#): > > I thought the alarm was a pure Homey threshold… Good point. If that turns out the case, you should post an issue [here](https://github.com/TedTolboom/com.xiaomi-mi-zigbee/issues). ---

I tried yesterday to change the threshold value while regularly clicking on the pairing button. The only result was loosing the device ☹. Homey has not been receiving data for 18 hours. ---

Did you short-press or long-press? Long-pressing puts the device in pairing mode. Try pairing it again with Homey (don’t remove it from Homey first). ---

it was multiple short-press… may be it drained the battery and it is now too low to transmit the data to the Homey. I also opened an issue. A rapid look at the code makes me guess that the value is hard coded to 20 (but I don’t know where to find the configuration value…)
