P1 with 3 phase. Development needed.

[christiaan.v]

Hi all,
last week i got my P1 meter installed. (smart meter / slimme meter).

I first had it connected via serial USB, works good.
and now via ESP8266 (p1wifi-gateway), also works perfect....

If i look at the MSG from the meter it looks like this:

Code: Select all

This is a DSM 5.0 message. it contains al lot more information then the older versions.
So i was wondering how i can use some of this information.

I have 3 phase connection in the house, each phase serve a different part of the house, so intresting to have these seperated counted.
Currently only the total of 3 phase are counted.

I noticed that someone resently had added the 3 phase voltage counters !!! Nice. currently only in the development brance, but working very nice.

Code: Select all

0-0:96.14.0(0002)		<-- Tariff indicator
1-0:32.7.0(231.3*V)		<-- Volt Phase 1 (already on git)
1-0:52.7.0(230.4*V)		<-- Volt Phase 2 (already on git)
1-0:72.7.0(232.2*V)		<-- Volt Phase 3 (already on git)
1-0:31.7.0(000*A)		<-- Ampere Phase 1 
1-0:51.7.0(002*A)		<-- Ampere Phase 2
1-0:71.7.0(000*A)		<-- Ampere Phase 3
1-0:21.7.0(00.172*kW)		<-- Power Phase 1
1-0:41.7.0(00.469*kW)		<-- Power Phase  2
1-0:61.7.0(00.053*kW)		<--  Power Phase 3

Who can add the other counters?

+1 , I would also love to see the 3 Phases Ampere counters in the graphs, very useful information when you sometimes overload one of the groups

[enboer]

Yes I would like to have this as well. It does not need to be in the graphs, but the P1 smartmeter takes only the first 5 fields from the meter. It would already be fine for me if it would read all the 36 lines (in my case). With scripting I can read it myself.
Running eg a python script to read it as well is not an option, because after this Domoticz does not update the meter anymore

[freijn]

Can you please share how you connected it with the ESP ?

[enboer]

I have the smartmeter connected via USB cable (not self build). and Domoticz runs fine. But I have also run this script http://gejanssen.com/howto/Slimme-meter ... itlezer.py to read the USB port as well I see a message: Error serial port close, End of File. After this I need a reboot to get Domoticz to update the meter again.

[sater]

Is there someone doing development on the code for this interface?
If not I could try, am well versed in programming, C and Python.
Have no experience with Domoticz development yet.

My main interest is getting the Ampere's per phase from my E350 smart meter.
I might be able to do something clever with my car charger.

[gordonb3]

These counters were added on November 8, 2018.

Not real sure how these could be interesting though. Amperes look to be integer values and you could get more detailed information (i.e. mA) by calculating these values from the phase kW and Volt indicators. The main issue as I see it is that these values are not counters and I also don't think they show averages but are in fact snapshot values. As such I would be very amazed if the sum of these values made during a day would result in the same value as the 1.8.x counter increment that is already logged. Especially on DSMR 4.x that only sends a message every 10 seconds and you could easily miss peak consumption from anything that is sensor controlled, like a fridge or oven.

Upgraded to 4.10242, enabled new devices, and it works.
I get three phases use and one delivered(my solar panels)

Great.

[rvdartel]

Yes please. More development. I want to read out 3 phase from my P1 meter.

[djtaz]

I have the P1 USB cable installed and it is showing the power per phase correctly. But it is in Volt and I would like to see this in Ampére to see the max load on each phase.

The rest is fine with the max Watt in total

[domoticzag1]

Bump!

Would love to see the Sags and Swells aswell, my meter is spitting the data out so it shouldnt be a issue to implement!

[enboer]

I updated some time ago, so I do not exactly know when it was implemented, but I now have 3 new devices in my devices list which shows the Power of each phase:

3Phase.JPG (97.65 KiB) Viewed 3345 times

These are 'subdevices' of the smart meter.

Also noticed This a couple of months ago.
But the Smart Meter outputs more data, like voltage sags and swells, even line voltage and current possibly.
Homeassistant already shows this data.

Unfortionetly we are not getting any reactions from the domoticz developers on this topic...

[kruisdraad]

Hi,

how did you build this up? I want to have these items as well but still limited to the voltages. Can you share this?

I do see some guy (looks dev) saying you can do this per phase ... but the values to exactly match so i don't know why he keeps pushing on that

[rvdartel]

I want this also, please share. I have an electric car and want to see the load of each Phase
THX

[giton]

Same request (more development) has been also requested through viewtopic.php?f=14&t=34255 as ampere per phase is avalaible now in mA and no more rounded to A.
