Reactive Power
I wanted to see reactive power with my WEM3080T and FW i.91.063T2. So I enabled it via Settings page:
After reboot, the meter did not connect to the Wi-Fi but came up as AP. So I configured my home network. It connected again but I can't see reactive power in the Local Monitor Lite:
When issuing the monitorjson command, I don't see the EA entries either:
{"method":"2-5","mac":"047863BBDCA5","version":"i.91.063T2","server":"em","SN":"2038DB69","Datas":[[236.3,5.070,-1195.0,1587.838,8469.330,49.97,1.00],[236.3,4.130,-940.0,3285.165,6991.455,49.97,0.97],[236.2,3.920,-905.0,2900.036,6696.010,49.97,0.98],[236.2,0.000,-3040.0,5771.151,20157.016,49.97,0.98]]} |

What am I missing?
So there can only either be net metering or reactive power metering?
Guess this is a limitation of the metering IC? It would however also be possible to at least calculate reactive power with active power and power factor, no?
Hi, it is not limited by th metering IC, but we do not think there is a real requirements that needs both reactive measurement(industry) and NEM(personal home), is not it?
Well, it would have been quite interesting for me and my dad. We saw a rather high current at a rather low power consumption. Of course one could have guessed it was reactive power then, also by looking at the power factor. The cause for that was the Viessmann geothermal heat pump drawing a high reactive power in standby.
