Hi,
As part of a project we have bought several DW2 sensors. Most of them work alright, however a small amount (3 so far) have the same issue posted above. The three sensors - they were working fine for a few weeks - became offline; nothing happens when reseting them.
We have run several tests on the three malfunctioning sensors (as we do have additional DW2 sensors). These tests ran from:
- Testing the same batteries on another DW2 sensors (there is no issue with the other DW2 sensors using the batteries)
to
- Leave the three unresponsive DW2 sensors on "stand by" for 24 hours. We did this with and without the batteries (no response).
The three malfunctioning sensors seem dead (we don't know why).
Could this be (as mentioned above) an issue with a specific batch?
PS: we got these sensors about 4 months ago
Kind regadrs
