The price wasn’t too bad for me. I didn’t have a very high income, but I paid for my ISDN myself.
But I do remember the improvement after switching to DSL, even if this was the early days of DSL that didn’t work thaaat great, it was still way better than analog modem or ISDN.
I don’t know if this is exact enough, but I use IKEA switches and IKEA or other ZigBee bulbs.
The switches looks like a different brand of paddle switches. They work like “dumb” paddle switches as a starting point, and then you build smartness on top of that.
If you do it right, they also work when internet is down and your server is crashed. Actually this is how they work out of the box. (I think the bridge must be powered on, but if you don’t have power…)
