Develco SPLZB-131: power_reactive (VAR) reading

[emandtf]

Useful to distinguish between Capacitive and Inductive load (negative values are common for negative-energy).

Maybe other Develco SPLZB-13x could have same capability, but I don't have any of them.

thanks!

@emandtf, @Koenkk, it seems that this change caused incorrect power measurements. All my 5 SPLZB-131 devices now report 100 times less power.

There isn't any relation about previous or other types of measurements. This commit regards a NEW value and nothing is changed to normal ones of the way them are retrieved/read/parsed.
I'm using this code/commit for all my 11 SPLZB-131 devices from middle of April and all is working well for all kind of measurements.

I have no better guess – it's the only change for this device in 1.31.0. Downgrading to 1.30.4 solved this problem for me.

@emandtf, now report 100 times less power.

Please open your "z2m/data/database.db" using a normal Text editor and check for multiplier/divider values for those 131 devices, and check if they are correct or fix it if needed, then restart Z2M.
I had a similar issue 1 year ago when something (I never discovered who and why) changed those values and power was 10-100 times less than the real ones.

For these kind of values:
"activePower": 80
"rmsCurrent": 393
"rmsVoltage": 23772
"acFrequency": 50020
"reactivePower": -5

Correct "database.db" values are:
"acVoltageMultiplier": 1
"acVoltageDivisor": 100
"acCurrentMultiplier": 1
"acCurrentDivisor": 1000
"acPowerMultiplier": 1
"acPowerDivisor": 1
"acFrequencyDivisor": 1000
"acFrequencyMultiplier": 1
