Why are we missing a targeted forsale/wtb section? I could see people might retire their external plugs, switches or sensors in favor of in wall devices, they might upgrade to units that monitor power or might upgrade their RPi2, 3 or 4 to a more powerful server which would leave hardware to repurpose or dispose of. With Tuya devices unflashable at the moment, it would be good to maybe have a known device up for purchase.
I know I went from an RPi3 to a Lenovo M73 and I am thinking about bumping up again, great hardware but might consider moving it if I upgrade.
I think it would be very nice to be able to offer it up to the community where someone would appreciate the comfort that it is working or has worked.
