I have a few Wemo devices that have been obsoleted by Belkin. The lights are zigbee so paired just fine with the sky connect dongle. this is the controller, I pulled the board with the now dumb smarts out and in the base is a nice 3.3v power supply. so printed a separator from the scary voltage, and reused the headers to bring the low voltage up to the esp32. I needed a Bluetooth proxy in the lounge for a few Shelly remotes I picked up.
That's one badass-looking solder-sucker
those silicone tube tipped ones are awesome. squishes and contours around to seal the spot for better solder removal and replacable tip if it gets damaged
Pity I'm terrible at using it. I'm going to have to look up some tutorials. I ended up chomping off the pcb around the headers
