Domoticz

hi guys
version 2024.4
raspberry pi 4

some times when i unplug/plug power supply of raspberry , domoticz go to offline , when i want run this manually with this command "./domoticz" i have this error :

Error opening SQLite3 database: unable to open database file

Of course, I have made a change in Raspberry. After all the settings in domoticz, I put my sd card in read-only mode. Could it be because of this or is the problem from somewhere else?

I don't think "./domoticz" is the way to start domoticz.
Try "sudo service domoticz start"
(not sure of the sudo is needed)

my domoticz is in startup and always auto start. but some time with unplug/plug or reboot can not auto start and i check with ./domoticz for see errors. i see i have this error . after several reboot or several unplug/plug again auto startup domoticz and worked. but this is not true and Annoying

If your Domoticz database is also on that read-only sd card than this probably is the reason your Domoticz will not work....

I do read-only for protect sd card (stop crash SD)
so are there any solution for protect sd card?

The database needs to be updated somehow on a disk. So you need a writable disk. You could invest in adding an SSD to your Pi. Or use an high quality SD
