Often you find others in troubles for not having the correct powersupply for the Raspberry.
The Raspberry starts complaining but only in the UI of the o.s.
After reading again that somebody was in troubles because of this, I decided to write a little script for monitoring Raspberry Pi sensors
which are not (yet) available in the standard domoticz UI.
Please find below my code.
- paste it in the events under Dzvents-Timer
- Create an Alert sensor and note the IDX
- change the 'Alertidx = 4106' into 'Alertidx = [yourIDX]'
Hopefully your Raspberry Pi is a happy one
Todo :
- I could not get the Lua bitwise AND function to work, hence the workaround,
if somebody know how to implement it, please share it with us.
- Notifications sent if alarm appears.
