Domoticz

I recently bought an Aeotec energy meter gen 5 60A, but that did not fit over the cable of my solar panels I wanted to measure, so I exchanged it for the 100A version which has a bigger clamp.

Adding to Domoticz went fine, but I cannot get for the life of it to spew the right numbers. It reports Watts, kWh and voltage. The voltage is just fine hovering round 230, but the watts (and thus the kWh) are off by a factor 500!

The watts reported do go up and down with the actual watts my inverter reports.

Reported vs Inverter
3.6 watt vs 1890 watt
3.3 watt vs 1655 watt
4.3 watt vs 2110 watt

I have to run between the inverter and the computer so the factor its off by is not always exactly the same, but it's around 500. Anybody any idea what to look at?

I have toyed with the settings (a lot)
turn the clamp around (report went from -2.2 watts to 2.2 watts)
excluded and re-included the node

Fyi i was never able to get a proper reading with hem. I'm missing an average of 25 percent of the daily total usage. Never figured why, played with the clamps, contacted with support... Everything seems ok, except the readings are off.

I have an Aeotec DSB09104 Home Energy Meter and it works well. Just a thought, it looks like your inverter number (1890) is in watts and your zwave device reported number is in kW. Also your inverter number may be just one phase where as the zwave reported number may be both phases. The reason why I say this is if you take 1890 times 2 then divide by 1000 you get 3.78, 1655x2/1000 = 3.31, 2110x2/1000 = 4.22. Just my two cents.

Clamp meter should only be over phase, and not over the complete cable with phase & neutral...

What do you mean?

What do you mean?

I think N1co means that you have 3 wires, a brown a blue and a green/yellow one. The clamp should only go over the brown one and not over all of them.

Please correct me if I miss understood.

Yes, I just installed one. In a one-phase system the clamp should only go over the brown wire.
In a 3-phase system the 3 clamps should go over the 3 phases, not the blue or earth wire.

Hello,

small premise, I'm a new user with Domoticz, in the past I used "DomotiGa".

I have installed Domoticz on my Rapisberry Pi 3, works well but my "Aeotec DSB09104 Home Energy Meter" is not well recognized. I'm using an AEON USB Z-Stick S2.

fast update of my previous post

I made an "hard reset" of the AEON Controller, now the Energy meter is "partially recognized", the point are:

=> the 2 clamps have save values
=> now way to change the energy meter config (for example I need to change country voltage to EU=240) the commands are queued but not send to che Energy meter.

Here some snapshot: do someone can help me ?

thank you in advance

Sorry for the late reply, did you get it fixed?

not yet, but now after Domoticz update, Domoticz doesn't work enymore

sudo /etc/init.d/domoticz.sh status

Look under Active: it says active (exited), it should be active (running). Try sudo /etc/init.d/domoticz.sh restart then sudo /etc/init.d/domoticz.sh status to see if this helps. It looks like you are missing libssl.so.1.1. Are you running the beta version, if so sometimes it has issues and needs to restarted. Also make sure your pi is up to date (I assume your running on a raspi): sudo apt-get update then sudo apt-get upgrade.

Are you in the US? I am, I am familiar with the wiring in the US electrical panels but not other areas. 90% of all mainland US electrical panels use a single phase system. One cable coming into the house. Inside that cable are two individually insulated wires with a another bare stranded wire wrapped around them. The bare wire is the neutral (0 vAC, the other two wires are the phases (A & B). The amp or CT clamps go around the two black wires, one clamp per wire. Either phase to the neutral is around 115vAC, phase to phase is around 240vAC. 115v is used for things like lighting and receptacles, 240v is use for things like well pumps, air conditioners, heat pumps, electric stoves, electric water heaters.

Please let me know what I'm missing. Hope all is well.
