I recently set up my "dev" ovms module to give me a method to power cycle my home firewall and I thought I would share with the list. Originally I was using a pfsense SG-1100. This particular version uses a problematic emmc flash memory for the system filesystem. These are not very robust. After years of flawless operation I started having trouble with lockups. This made me search for an out-of-band method to power cycle it. Remembering that I had some of the prototype ovms pcb's Mark made (and some DB26 connectors) I decided to use a solid state relay to interrupt the power to the firewall (via the ovms cellular network connection). By this point I had replaced the SG-1100 with a SG-2100 that I got from a buddy (with a nice M.2 slot replacing the emmc). It has a locking power connector and I was able to find compatible switchcraft inline parts. Using a type B solid state relay (normally closed) power is not interrupted when the ovms module is rebooted. Here's the script: vfs cat /sd/scripts/pfsense-cycle egpio output 9 0 sleep 5 egpio output 9 1 To run it I paste: script run /sd/scripts/pfsense-cycle into the iphone ovms app. I've attached a couple of pictures.
