Smart fan
I bought an Arlec smart fan. It has a WR4 wifi module inside, based on an RTL8710BN. These are now supported by esphome.

And it all works mostly perfectly. OTA updates via wifi only work occasionally, perhaps inside a 30-60 second window after the RTL chip powers on. It takes a fair bit of bouncing the power and retrying the connection to get it to stick.
