Yes, what does "integrate" even mean? Most people mistakenly think it just means on/off or maximum dimming, and then 90% of the time by pressing a button, in which case you might as well stick with conventional systems.
- Glass switches? Yes, if you like them. I know they are popular but of course mainly because of the price.
- Weather station, yes it exists, but usually you don't need it, so there's no point in talking about automation (eyes and ears).
- Underfloor heating manual again? Ideally, it controls itself naturally without external intervention, certainly not via switches.
- Yes, here and there you will need window contacts in whatever form (eyes and ears).
- You have to consider sockets, quite useful for scenes and information. Automation as a whole anyway. If you can't even control sockets (even just a handful), then why bother at all?
How can you ensure that the right lights turn on with presence detectors?
You have to detach yourself from the idea that presence detectors work like the well-known motion sensors from the bargain bin. Presence detectors have switchable sectors and more or less (depending on the manufacturer) precise settings of the detection zones. It is also important to consider where and how the detector is installed. Just through that alone, you can influence a lot.
