i’m trying to setup a NorthQ Power Meter 9021, but after inclusion neither configuration parameters can be set, nor any values can be read (even the battery level). I’m running openHAB 1.8.3 on a Raspberry Pi 2 with an AeonLab Z-Stick Gen-5.
Has anyone this device up and running?
yes, in the meantime i’ve got it to work. After one day without any changes the connection from openhab to the NorthQ 9021 was stable and both reading and setting parameter values works as expected.
You can find here a good explanation of the parameters and this is a good hint, how to set the important 3 values.
my Items: Number power_1_battery "Electricity Meter Battery [%s %%]" <battery> (gPower) { zwave="32:command=BATTERY,refresh_interval=10"} Number power_1_usage_total "kWh [%.4f]" <energy> (gPower) { zwave="32:command=METER,meter_scale=E_KWh,refresh_interval=60"} Number power_1_usage "Watt [%.2f]" (gPower)
my Rule: rule power1_current_usage_update when Item power_1_usage_total received update then power_1_usage.postUpdate(power_1_usage_total.deltaSince(now.minusMinutes(10)).value * 6000)); end
i will send mine back, because it’s very inprecise. Sometimes the measured values are pretty good, sometimes they are just the half of the real value. Not really usable… The debug mode also doesn’t work, no LED at pulse counting.
