Re: RPI3 Does not run my system after weekend, but does during weekdays

I'm on my phone so it's not ideal. Your cron job to shutdown the raspberry pi on the 29th appears to begin shutting down at 17.00.12 but begins starting things at 17.00.13 are you rebooting the computer or shutting it down?

Re: Geany Debug Tab Not Shown

Geany is quite buggy.
Try 'gdb' in a terminal window.
Add breakpoints with b followed by a line number
run to start the program being debugged
print variable-name to inspect a variable

Re: Newbie, Adafruit MotorHAT, and Stepper Control Program Modification

Re: Is a Raspberry Pi suited for this?

I'd use light bulbs for the oven and washing machine. The oven draws a decent current and generates lots of heat. The washing machine has a current drain only (water heater and motors)

Re: Connecting Pi to The Cloud for WiFi

Have you entered your wifi password in your wpa_supplicant. It's in your /etc directory

Code: Select all

find /etc -name '*wpa*' 2>/dev/null
will locate it. I would give a more exact location but my raspberry pi is out on loan

Plug a usb drive in, ignore the password request. In a terminal type

udisksctl mount -b /dev/sdb1
