I just bought a bunch of Shelly wall switches and US outlets. They are very affordable and use an open source OS on what I think is an ESP32 enabling Bluetooth and WiFi. They have an IoT cloud thing paired with their app BUT you can disable their cloud or use your own cloud URL, enable RPC over http or UDP and write your own code, use MQTT, local web server in the switch, etc. The outlets are just relays though they measure load current and voltage. Bonus is they do not need to be commissioned through an app - you can do everything over a browser or http calls via curl so you can use whatever OS and even script it. My only gripe is the wall switches do not have any ability to accommodate retrofitting a 3/4-way setup which is quite common for stairwell and hallway lighting.
