Battery Monitor 12 Volts

[fabio schinaia]

Good morning,
I can't find a Battery Monitor for my 12 Volt DC battery.
Is there a Tuya device that measures Volts, Amps and battery state of charge?

Hallo, I‘m also sad, that there is no solution for battery monitoring (12V, 24V, 48V). Just simple voltage and capacity.
Europe, speciell Germany, is a great market for solutions in PV-energy-managing - even when you can use scenarios like „case when capacity higher xx% then switch on… or less then xx% switch off…

Why has anyone answered? The answer is also important for shareholders if tuya supports solutions for energy-managing - or not!

Kind regards from germany
