A Beginner's Guide to the ESP8266
For the ESP32, an hero is in the process of adding LVGL to ESPHome. You can try it out now: https://github.com/esphome/esphome/pull/6363
Here's the (very good!) preview documentation: https://deploy-preview-3678--esphome.netlify.app/components/...
This is such a game-changer for me that I'll be using the ESP32 over the ESP8266 for any projects involving displays from now on.

ESPHome
Solid state relay is probably a bad idea with all the extra heat-sinking, extra cost, and chance of getting counterfeits.
I do this with ESPHome & a J115F21C12VDCS.9 relay (note only the NO side is rated for 40A resistive): https://i.imgur.com/MqqOkoY.png
Choose any of the temperature sensors here for air temperature sensing: https://esphome.io/
Configuration is so easy. For the sensor, just copy the config from here, for example: https://esphome.io/components/sensor/bme280. Add a gpio output (https://esphome.io/components/output/gpio) and a bang-bang climate controller (https://esphome.io/components/climate/bang_bang.html)

Thoughts, learnings and regrets after three years on Home Assistant
You can do this with a $30 Sonoff S31 running ESPHome [0]. Since the Sonoff wall switch can run a ping sensor against your server you could create a watchdog automation right on the S31 to shut off the mains power to the S31 switch and turn back on after X seconds.
There are other ways you could have the S31 do operational checks but ultimately ESPHome is probably an interesting consideration and supported by tons of off the shelf hardware.

Fixing a broken smart cat feeder with ESP32
They're pretty great and compatible with most things. ESPHome [1] is a great resource for getting ESP32's working nicely with HA and you can find lots of projects using it to learn from.
You'll likely need to do soldering if you want to connect sensors, batteries and the like.
Personally I really like what SEEED Studio [2] does with their ESP32 boards and they have nice docs.

How to connect a SwiftUI app to NodeMCU ESP32
Maybe you could set up ESPHome on the ESP32. It might make connecting those components easier, plus a decent web server built in. Then your app can be set up to access data provided by the ESPHome web server.

Adafruit Feather ESP32-S2 with BME280 will not work!

Hey all! ESP32 beginner here, looking for a little advice
Probably an unpopular opinion, but for the simple stuff you may just want to use something like EspHome where you just need to create a yaml file. Once you’re comfortable with that maybe get into something a bit more advanced, but esphome make it a breeze. It integrates with home assistant if you already have that in place as well.

There's some other good tutorials for it as well, https://randomnerdtutorials.com/?s=esp-now and https://github.com/HarringayMakerSpace/ESP-Now

Powering 16 ESP01s with servos
For power, I'd recommend Li-Ion primary (non-rechargeable) cells, whatever size works best for you. Those have essentially zero internal leakage and a 5 year shelf-life. If you've done it all correctly, it's conceivable it could be 5 years before you need to change the batteries (on top of a 30' ladder). You'd need a small high-efficiency buck converter to drop the 6.8V batteries down to 3.3V for the ESP, with a separate switched 5V linear regulator (one with a SHUTDOWN pin) to power the servos when they need to be driven. The ESP will consume 16-20uA in Deep Sleep, and the buck converter should mostly be off, except for when the ESP wakes every 3.5 hours (maximum Deep Sleep interval). If you're already using ESP-NOW to talk to the vent ESPs, then you could do a 'vent changed' check every time it wakes, otherwise it's more efficient to go back to Sleep quickly and wait until 12-24 hours has elapsed before you fire up a full WiFi connection. Not counting buck inefficiencies and servo movements, the ESP would only consume about 175mAh per year. The batteries will expire before they empty, maybe in 6-7 years.

ESPNow to Wifi Gateway - part of an Ultra Low Power Sensor project
I presume you've seen Anthony Elder's examples? He got a single ESP to act as hub by restarting it. In a low-traffic environment that'd work. There was discussion and a new PR to speed up the reconnect time using WIFI_RESUME that's been merged in the git repo, which should make a single-ESP hub faster to respond. You'd need a little fault checking in case the BSSID changes of course, but for the normal case things would be faster.
