I looked through the GitHub details and it talks about connecting the thermostat via USB to flash it. I really only have Chromebooks at home and I'm not sure how well that would work on Linux container.

Thank you, getting old sucks. Didn't even see that.

If you already have a light switch there for other reasons you could use something like the zoo zen32 scene controller switch. It is a z-wave switch for the circuit you install it on but adds 4 additional buttons. You would use those buttons to trigger automation or set a scene.

Hmm, I confirmed cloudflare module with "caddy list-modules" and see:

<list of standard modules>
  Standard modules: 127

dns.providers.cloudflare

  Non-standard modules: 1

  Unknown modules: 0

But when I do a reload I get "Error: adapting config using caddyfile: Caddyfile:12: unrecognized global option: acme_dms"
