I would really like to be able to control the battery voltage. And depending on the voltage, turn the payload on and off. Very relevant for solar backup systems.

Do you mean using voltage as triggers?

Yes. at different battery voltages, you can perform or complete certain tasks. Boiler, watering the lawn.

It would be a brilliant solution if such a meter was simultaneously powered with the measured current. This would enable isolated voltage/current measurement of solar panels. I am currently using PZEM-025 for this purpose, but it cannot send data over the network to another device…

Same for POWR316D and other POW devices.

I love this device and since it already measures the voltage, why not add a setting to disconnect if voltage goes above or below a trigger level?  
(It already has this feature for power and amps in scenes, but not for voltage).

This could be useful to protect against over/under-voltage which may occur e.g. with brown-outs or genset supply.
