How to best control and read from 'drone' rasp-pi's?

Configuration
1

Hi -
I have HA installed on a VM on my NAS which is my master/main HA install. I’m setting up a few raspberry pi’s around the house to do certain things - one is going to be the cpu behind a touchscreen UI panel in the kitchen and an hdmi/CEC to a TV (pi 4 w/ 2 hdmi’s), and another is going to be in my attic with temp sensors on the gpio port and a usb rtl_433 listener for my weather station.

I’m trying to figure out how to use HA on these ‘remote’ devices so that I can achieve several things:
In the kitchen:

  1. be a touchscreen UI panel (https://www.reddit.com/r/homeassistant/comments/o8ys14/dashboard_show_off_flush_10_touch_display/)
  2. control the touchscreen power/sleep state (like, turn the touchscreen off at night and on in the morning, tho i’m not sure if the touchscreen is CEC capable)
  3. Control the kitchen TV (HDMI-CEC, power on/sleep, change input, change volume)
  4. Read temp data from a gpio one-wire temp sensor
  5. bluetooth to kitchen devices (like this - Anova sous vide control over MQTT)

Attic:

  1. Read weather station data (rtl 433 - RTL_433 to MQTT with Acurite Weather Sensors and Itron Water Meter)
  2. Read power/water/gas meter stats (same post but further down - RTL_433 to MQTT with Acurite Weather Sensors and Itron Water Meter - #2 by gregmac)
  3. read temp data from multiple gpio one-wire temp sensors

What’s the best way to go about linking these devices back to HA? I want to read and log the weather station and energy meter data, i want to log the ambient temp in the kitchen, and I want to be able to push a button on a lovelace panel from my phone or from the touchscreen and change the kitchen tv from hdmi1 to hdmi2 or turn it on and off, etc.

Thanks!

I’d go with MQTT for the transport protocol. You’ve already provided links to many pieces of software that use it.

This looks quite useful. I’ve never used it though.
