All items (switch) switch on without any reason

Hynek_Prokop · April 3, 2023, 3:52pm

Hi,

I have Openhab 3.4.2 Release running in docker container. I have a problem, that sometimes all the “switch” items switch ON. Usually during night, one time it also happend during the day. It happens aprox. one time per week, at different days and time.

I have OpenHAB Cloud connected
I use OpenHab Android App with Alarm time synchronization enabled
I use one rule which switch on one light at “Alarm” time (synchronized from the phone).
I use Siemens PLC binding which control lights. Light status (ON/OFF) is stored in PLC. OpenHab just send commands and show actual state.

I checked Openhab Log. I can see there “received command ON”. But I dont see from where is it comming. Which Logger I should change to see more details? See actual Looger config bellow.

Does anybody have some idea what could be wrong?

Thanks.

OpenHab Log. See item “BedroomLeftWallLightSwitch”. It switched ON by itself. Later I switched it OFF from the phone App.

Check your network configuration very carefully. 99 times out of 100 this sort of activity means that your OH instance is open to the outside internet and someone else is accessing your system and turning on your lights because your system is not fully secured.

Test it for yourself. Go to shodan.io and search for your external IP address. If you see openhab listed then you know it can be accessed from the web.

Well, that’s my shame. I was 100% sure, that I closed it after test I made long time ago. Thanks a lot.
