Hi all,
I have a same device, which stopped detecting motion after year(s) of operation. I believe I had no issue with the latest firmware 2.2.4.
Closer inspection reveals within a 1 - 2 meter range there is motion detected, not not at longer range. Changing the sensitivity setting does make a little difference, but it is not as sensitive as it was in the past (value 40, courage whole floor).
Is there a way to inspect/measure the components inside?
Al other operations seem to work OK (tamper, battery, luminance, wifi....)
