@zimpenfish @Sarahw Well, yeah, I've been thinking that I ought to document the household IT one of these decades. I think that when I try I will be horrified at how many layers there are, how complicated it is.

@zimpenfish @Sarahw I *think* the most complicated thing you can do is:

"From outside the house, connect to #HomeAssistant by phone and check what the outdoor temperature at home is."

This involves dynamic DNS service, certificate service, custom hole punched through Giffgaff's normal blocking which took weeks to negotiate, port forwarding through two layers of routers, and that's just to talk to the Raspberry Pi in the house. The outdoor temperature thermometer is however hooked up to the Raspberry Pi in the greenhouse, via an undocumented PCB with all sorts of things soldered to it, which is connected to the internet via some wires and a wifi access point in the garage. It uses some code in the Pi to read the thermometer and upload it to a database living in the cloud with my web hosting provider (multiple layers there from PHP to domain rental) from where it's pulled down into Home Assistant as a remote HTTP sensor.

And I'm sure I missed a few. Nah, never going to document that, far too much like hard work.
