Hi,
I’m mostly done with all the plans for my home automation, but my house construction experienced some significant delays, so I’ll be proceeding with installations only about Spring next year.
I gave up on wiring everything, ie. light switches.
My HA will rely heavily on integration with the alarm system, but the alarm system will be operating completely independently from the home automation, meaning it’s the primary system in my house. HA will read Alarm sensors’ status over API that is available for Satel’s Integra device. This way I will have access to presence in almost entire house. In some additional places I also plan adding HA controlled WIFI presence sensors from Athom: https://www.athom.tech/blank-1/human-presence-sensor. The power supply will be delivered from the UPS supported circuit (whole alarm, wifi, and HA will be 100% always on).
All windows and external doors will have built in contact sensors (already installed).
For light controls, I will use combination of matter in wall controllers (Sonoff MiniR4M) and smart switches (didn’t decide yet which one, both Sonof’s M5 (esphome flashed) and Athom’s (factory enabled with esphome) are great candidates.
Smoke sensors, gas sensors and water leakage wired sensors will all be connected to alarm system, not HA, and also accessible for status read over API.
Surveillance will be independent system. I decided to use Hikvision (recorder and cameras). HA will have access over API to display video.
For audio I decided to use Sonos’ speakers, in wall in the living room Era 300 (I have one already) in the Gym room and ceiling mounted if I decide to add more elsewhere.
For panels, you can see my prototype here, but I’m not going to use it. 11" tablets are too uncomfortable, and largest you can get is 15" at high prices.
I will use raspberry PI 4b connected to HDMI touch display of 15"-18". The wall socket will include 230v, eth and 12v power supply. In wall socket with a pocket will hold PI and power adapter from 12v to USB (which is strong enough to fuel both PI and display - PI delivers enough juice from the USB port to keep the display running, that’s amazing).
Re Wifi, network APs etc read more here.
So far I didn’t find good solution for wired temperature and humidity sensors to connect to HA. I’ve put this on hold until my heating system is installed. The heat pump will have temperature control in every room. I hope I’ll be able to integrate reading those sensors into HA, but don’t know yet. They for humidity I’ll search later, as well as with recuperation/mechanical ventilation and air conditioning integrations. All systems will be wifi enabled, but not sure if I’ll be able to integrate them with HA yet.
