I just wanted to see what other selfhosters backup emergency plan is if the primary internet router goes offline but the internet isn't out (ie a router reboot would fix the problem), leaving you without access to your stuff even via vpn.

the options I've considered so far:

1. cellular smart plug to reboot router

I tried a ubibot smart plug (SP1) that is supposed to work with cellular, but the device or sim is bad. I'm currently troubleshooting. The problem with this one is it requires a proprietary cloud service, it's supposedly self hostable, but it's a pia to setup and their app port can't be changed easily allowing for a reverse proxy setup on VPS.

2. the other option I am considering is cellular wifi router and a wifi smart plug connected to that device to reboot router

what other options have I overlooked? Also, specific models of devices would be helpful info from others doing this already.

TIA!

Edit: also just thought of possibly a cellular internet backup on my opnsense box, but from everything I've read that's also very involved to setup

Edit2: I've setup a homeassistant automation to reboot a zigbee smart plug if 2 external hosts are down for 15 mins, will try this out for a bit. I still need tp troubleshoot why the device goes down in General. Thanks for all the responses and ideas!
