Hi all, i have spent a fair bit of time trying to learn on my own from the various available resources. so far so good i have set up my Openhab 3 on RPI4. I have some questions whihc i havent been able to answer yet. if you enable wifi (via opehabian confi/ssh) does this replace the ethernet co…

Question 1: It doesn’t replace the ethernet. You’ll have an additional network interface. Question 3: You can read the temperature of your Raspi with the command “vcgencmd measure_temp” or reading the file /sys/class/thermal/thermal_zone0/temp But you need to write a small script that you can c…

[image] alexkarageorgis: but i cant tell if hte backup is setup on a schedule. Read the docs more carefully please.

@JensD hey ty for that. i kinda got that far, i.e. i can run the command in ssh, i was hopping there was a simple binding way but your point creates a new question. if not how do i execute code like the one you mention? do i need the exec binding? or do i place it in a rule/scirpt? and what do i r…

it’s a built-in action you can use in rules, no need to install a binding :wink: You can then assign the return value of the executeCommandLine to an Item which you can display in habpanel, e.g. RaspiTempItem.postUpdate(raspi_temp). Don’t forget to create a Number Item you can use for that.

[image] alexkarageorgis: I want to monitor the temperature of the RPI incase there isn issue somewhere. what is the best way to bring it into the system. system info doesnt appear to have temp data. Personally, I wouldn’t worry about it. Many of us run our RPis without fans and without issues…

Hi @mstormi i did read the doc you mention - you made a couple of times (part of why i asked point 3). it isnt exactly clear for me that the trigger event you mention works . the main reason is that the instructions talk about 53 Setup SD monitoring but what i have in open hab in 53 is setup SD m…

[image] alexkarageorgis: So i was worried that it is an old document. Then why didn’t you ask that? It obviously IS a typo, you would have just needed to read the full sentence or run the config tool. [image] alexkarageorgis: every 6 months it updates the full thing and every day an incr…

@mstormi i will ask next time, still trying to learn while i read. got your point. but do consider that while you may know the difference between rsync and backup i am not there yet. Thanks.

I do actually have a number of UPS in the house. they arent connected to the RPI yet but i will certainly see how i sort what you propose. thanks for taking the time

So to answer my own questions for future generations [image] alexkarageorgis: if you enable wifi (via opehabian confi/ssh) does this replace the ethernet connection or is it a backup.I have enabled it a couple of times and it seems to hang. so before i try it again i want to backup the sd card…

Personally, I wouldn’t worry about it. Many of us run our RPis without fans and without issues (though I can’t say that no one has had issues). Don’t let that stop you if you just want to do it for the heck of it, though.

The bigger concern is power outages. If you don’t already have one, I recommend getting a UPS.
