These little boards are great - I'd recommend the isolated version for anything that might be referenced back to ground potential.
We have one in an OpenEVSE, it's been ticking along no problems for a couple years now. In that scenario, in theory the PoE allows the ESP32 to detect if the EVSE breaker pops - I've not had that happen, but it seemed like a worthwhile feature to consider ;).
