As far as I know that’s not possible for WhatsApp.

I use INWX (based in Germany). Prices are consistently low (not always the cheapest, but fair). The web UI is a bit rusty, but it works perfectly and you can manage everything there.

That show is equal parts content and advertising. That is a bit too much for me…

The easiest thing: We use a motion sensor to automatically turn on the light for the stairs. You wouldn’t need Home Assistant for that, but with a little more configuration you can adjust the light levels and colour temperature based on the time of day (not as disturbing at night). We have two rooms which have problems with humidity in one a fan is automatically turned on (basic) in the other a dehumidifier is triggered based on the outside and inside temperature because there are large windows which are producing a lot of condensation otherwise. Now the really specific stuff: My daughter has Diabetes and we need to manage her blood glucose levels. There are alarms but ideally you would act before they are triggered. So we hooked her blood glucose levels to a light in our bedroom which turns on if her levels are getting out of bounds at night. That way she isn’t woken by the alarm, but by one of us and can go back to sleep much quicker.

That’s easily Home Assistant. It got me into the whole home automation stuff and I have gradually included more and more parts into it - including some health related stuff. It really makes my family’s life easier and helps us organizing it.

That’s the way to do it. The problem is that the request originates from the browser of you website visitor. You need to open a path for them to you media server. Nginx and it’s reverse proxy functionality is exactly what you need for that.
