Thank you for the advice, but it’s not really what I’m looking for. I am looking for something really lightweight for now, and the ESP32 is a bit overkill. And codeless deployment sounds horrible, I want to actually write the ode myself, I should have mentioned that!

+1 on the ESP32.
Very good support (incl Arduino framework which means tons of libraries for sensors), cheap, tons of variants of chips and dev boards for all sorts of purposes, plus if you buy a ready made module or dev board, you don't need wireless certification (as those come with it).
Tons of pins, tons of processing power, built in wireless support for WiFi, Bluetooth, Thread/Matter (depending on model).
And you can utilise ESPHome if you want to go for a practically codeless deployment.

Unless you’re making thousands of something, an ESP32 is cheap enough that it shouldn’t matter whether or not it’s overkill. Getting something simpler will only save you a few pennies unless you’re overspending as ESP32 breakout boards are available for less than £2.
The power draw will be a problem, though, unless you disable WiFi. They’re not really button-cell-friendly.

Esp32 will demolish a full sized battery, never mind a coincell.

All fair points, assuming you write all your code yourself. But WiFi is still a pig even with optimization, coin cell is impossible which is what he/she asked to use.
