That would be against the specification to also read line voltage and phase; this requires an own power supply. One death you have to die...

By the way; for an v2 this is freakingly easy to achieve by a POE-splitter; of course you should keep the voltage for the FLM within a reasonable range to not fry the internal voltage regulator; but even this would be achievable by an extra LM2940... Be creative!
