Re: Pi not rebooting after power failure

No idea why they do not boot after a brown out but a few ideas that may keep them going. 1) Hats with batteries on them are available. 2) Look to use the internal watchdog timer to reset the Pi 3) Look to use a Hat with an external watchdog timer on it 4) Build your own watchdog circuit using a 555 ...

Re: Raspberry Pi 4 boot time > 2 minutes

How about just working through the questions rather than jumping around it makes life hard for folk helping as they can be duplicating questions and contradicting as we do not know why you are doing things.

To set the dhcp range change
dhcp-range=192.168.4.2,192.168.4.20,255.255.255.0,24h

Re: How to "auto run" an executable file from rc.local ?

Files in that folder are normally owned by www-data as that’s the limited user for web services.

I would rethink the location / security plan and not mixed root with www-data as it will turn round and byte you one day if something has root access via web service. Not good.

Did you check the SHA value of your download vs the web value - it may have been corrupted. As above - did you verify the write on the SD card? It could be a duff one?

Re: Copying Sensorpush Sensor Temperatur and Humidity

Main issue you will have is creating the app on the mobile. It’s highly unlikely (and possibly illegal) to match the device data transfer to use their app but there are many ways to simulate that. As you are new to the forum (welcome by the way) and I guess the Pi, I would start at the basics. Hardw...

Re: Dual redundancy raspberry PI

I wonder if its the test set as the A2 was slower on the 3B but about equal on the 3B+

Not tried it one in a Zero though.

In my mind, they are not worth the extra (esp as my cameras do not handle the A2 cards as anything special).
