Easily obtainable wall switches that will take Tasmota etc? (lemmy.ca)

I'm looking for a wall switch that I will take Tasmota firmware (so a ESP82XX chipset generally) but can get easily sourced and aren't a huge pain to reprogram.

I'm totally cool with soldering some serial jump points from the board of the appropriate Rx/Tx/GRND/3.3V and pin0 are readily available, but try to avoid stuff that requires soldering the chip itself.

I used to be able to get Globe etc dimmers from Costco that were flashable via the old OTA Tuya-Convert method, but that seems to be a thing of the past and I just need a regular ol' non-dimmer switch which is easy to find and access the required pins these days.

If there are switches which take 110VAC but don't output power, that's even better as some I'm just looking to supplement devices already have power but are inconvenient to access

I ended up using Aqara switches that talk to a Sonoff ZB BRIDGE-P flashed with Tasmota.

Sonoff TX series might fit your bill but I wanted a real switch rather than a capacitive one. Shelly are usually good quality but they aren’t easily available where I am: https://templates.blakadder.com/shelly_1.html

https://templates.blakadder.com/ is a pretty comprehensive overview of your options

https://www.zigbee2mqtt.io/supported-devices/ covers devices that are compatible with z2m

https://zigbee.blakadder.com/zha.html lists devices supported by ZHA

I started with ZHA in my zigbee setup but moved to z2m due to device support.

Edit: Be aware that some of the Aqara switches are quite big on the back and you may struggle to fit them. I use E series switches that are considerably smaller than other types.
