I’ll certainly take this under advisement, but as a practical matter, it’s a long way off if at all. I have an ESP32 bench prototype and do work on it as time allows, but building a prototype is way short of being manufactured, safety certified, regulatory testing, documentation, testing, and eventually selling. There will also be practical considerations such as whether to use the limited available pins of the ESP32 to support Ethernet or other functionality and what cost adding the connector and making enclosure modifications for it adds.
I’ve said in the past that the solution in hand is to use a wired access point in proximity to the IoTaWatt. We’ll see what kind of demand develops for this, but my sense is that it’s going the other way. Arduino and RPi used to be only ethernet and they had to migrate to WiFi.
Just sayin.
