I tried all sorts of port forwarding tricks to get wireguard working on the VM that runs my HA instance to no avail. The trailscale solution works really well. The only real problem I had was magic DNS conflicts with DNS66 on my phone (which I use for ad blocking). In the end I just used a hardwired VPN IP for my HA connection.

I have not, but I will now thanks.

I’m looking at Embassy too for a Pico project and combining it with a nostd mqtt implementation. However I need to understand Futures and if/how they relate to the async paradigm.
