Easily obtainable wall switches that will take Tasmota etc?

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.

- I was looking at those actually. Price isn't too bad although shipping to Canada is a bit of a pain, but it's nice that it is already Tasmotized!
- Yeah, I just got a few of the CloudFree Motion Light Switches and am quite happy with them. I had some trouble initially but then figured out I needed my 2.4GHz network to have a fixed channel, apparently that's a common thing with Tasmota on some chips. Now I have one pair acting as main/remote for my basement lights, and some others just acting as motion sensing switches but with the benefit of being able to monitor motion remotely.

The Blackadder templates page has become less useful over time as a number of devices have changed their chipsets and so it's a lottery if you get the "good" device with an ESP chip or the newer ones that don't support Tasmota :-(
