These can run ESPHome for Home Assistant with local WiFi only (doesn't use web) but requires a little dexterity with soldering and a little $5 serial to USB converter for the first flash. Subsequent flashes are over the air (OTA). Good write up here if interested:

I have 12 running in my home and really like being able to customize the polling/reporting speed for the power monitoring in Home Assistant. Supported in Tasamota [github.io]too.

If you have a 3d printer there are jigs that you can print for the pins. I've also taped the pins to the contact pads and the flash worked that way.

These are great switches and super reliable. I had them on my mining rigs chugging 1500w for years. Not a single one got hot or melted.

Do these also have passive BLE monitoring like the SwitchBot Minis?

I just used a header and soldered it on then used male-to-female jumpers. Easy stuff for anyone used to tinkering and good way to burn an afternoon doing a batch. Hardest part is holding that button long enough while plugging it in because you don't get any indication it is ready to flash or that you held it the 5 seconds. Smilie

I'm really happy with them and also very reliable to date. Lowest price I've seen. I head the newer S40 don't work so was happy to see the S31 available.

I didn't need to solder to flash. Just buy some test leads and clip them on.
