I agree, but most of them are potted, so they need a bulky socket. I guess I'll be doing some destructive disassembly.
I'd like to install this device remotely, near the load that is being switched. Does anyone have an easy way to generate Vcc from the mains? It can be done with a bridge rectifier, a resistor ladder, and a linear regulator, but the ESP8266 needs upwards of 200 ma when it's in transmit mode and the resistor ladder has to dissipate too much heat in order to provide a satisfactory voltage divider function to get down to a max of 35 volts feeding the regulator.
