God I miss the sense that a company is trying to sell me exactly what I want to buy. I used to get it so often in the early 2000s.
A year ago I bought a pack of 4 Meross smart switches. I was using one and had 4 left. The one had issues, about once every 2-3 months it would stop responding. I'd unplug it and plug in back in and it would work again.
Any, last week I wanted to plug something else in so I grabbed one of the remaining 3 switches. I could not get it to pair with the iPhone Home app (the same app I was using for the first switch). I tried moving closer to my WiFi (right next to it in fact). No luck. I tried all 3 switches. No luck. Ok, go online, Meross has an app that might let me do the pairing and/or apply upgrades? Download the app. You can't use the app unless you make an account. F that. I took all 4 switches that immediately threw them in the trash.
I searched and found Eve (https://www.evehome.com/) who "claim" they are all about privacy

They cost >2x the Meross ones. Got 2. They work so far. Crossing my fingers they're legit, though my guess is they won't last. Few consumers care AFAICT.
FYI - there are plenty of cheap Tuya devices[0] that can be flashed with alternative firmware[1] which works locally. More generically, there a lot of ESP32-based switches that work with Tasmota open-source firmware[2]. There breadth of devices is annoying because it makes configuration difficult since manufacturer wire up the relays differently, so it took me trial and error to figure out which device/"port" the firmware needs to toggle to turn the switch on or off
0. Any device that requires installation of a phone app named "Smart Life" or "Tuya Smart".
