this was the solution from Dimitar:
"
Update: BUG will be solved itself without firmware update, including ones with Schedules enabled. If you reboot devices after 23:00 in your country all should work.
We prepare firmware update but in this case we decide to make in Monday, because all devices will not have issues in few hours and many people cannot update them even there is new version.
ATTENTION: ALL GEN2 DEVICES. CRITICAL BUG!
- PLUS 1/1PM/2PM
- PRO 4PM/1/2
Updated:
We found a serios bug related to Day saving light time change and Schedules
Affect: devices stop working at all.
If your devices still working:
1. Disable Schedules
If your device is not work anymore:
1. Disconnect ethernet cable from your router
2. Reboot devices with power cycle
3. Found device IP in local network
4. Disable Schedules
5. Connect ethernet cable to your router
Our developers in back in the office and work to fix the issue and release new firmware with hotfix.
When is ready you can update your devices and enable schedules again.
We apologize for the inconvenience, we will do our best to fix the problem within a few hours.
