Ha ha, I tried something similar when I had to go to Thailand for my wife's treatment. And failed spectacularly. Fortunately, my laptop had all the files. I didn't have Tailscale at that time.

My Desktop, WoL on, tested to be working Android Phone, always on

All have SyncThing installed. Mobile had Tasker installed.

So, the idea was to have Tasker monitor a folder inside SyncThing, When I need my computer, I put a file inside that folder, when Tasker finds that folder, it sends WoL to my desktop, and deletes the file, Computer wakes up. When I see the file deleted I know, the beast is now awakens ....

When I actually did try that from Thailand, the file did not got deleted, nor the beast woke up.

What happened? Turns out, my mobile restarts automatically after some time of inactivity. Which, locks Tasker out, and the whole process fails.

So, operation wake the beast was busted.

Since you're already using Tasker, you could use it to launch Tailscale on the phone at boot - I've got mine set to do this so my phone reconnects to tailscale after a reboot.

Now I have another mobile with more control, so restart is not a problem anymore, and as I can SSH in to it using Termux. This basically handles all of my needs.

Now I just need to get enough momentum to set up the process of waking up my desktop as needed and set up radical caldav server in the mobile.
