I have actually found most of the Zooz devices DO NOT need to be paired again after updating. The only issue they have is the lifeline association gets wiped out. This would explain it as it sounds like you could send commands to the device and it would do the action (change LOED colors) but the device did not respond back. This is because it did not know where to send the response (due to missing lifeline association). Many drivers if you press configure will set this again (not sure if the ZEN32 driver does). I also built the feature into another tool I have worked on:
For any devices using my own published drivers I have the Association settings built into the Configure option. So what I do is keep the device page open with all the settings on it while I do the firmware update. This way if the settings get reset from the update I can set them back to the device right away. After the update I give the device a minute to restart then press configure to reconfigure the device how it was before. This may work on other drivers as well.
