Question for Tasmota template with 3 phases and 2 directions

[Brakelmann]

Hi,

I just tried the dbus-opendtu connect and it worked right away.
I recognized that it is also able to read tasmota values which is great.

I am using IR reader for my smart meter with an ESP8266 with tasmota to get the values via SML for the grid.
Would it be possible to adjust the tasmota template to work with three phases and two directions?

A screenshot of the Tasmota Web UI is attached.

Thanks in advance, Stefan.

It works already but single phase:

but your Tasmota has no power per Phase, please try to use the Single Current only for testing in template

I will give it a try and report back.

Energy = Voltage X Ampere
This should not be the show-stopper. I simply don't know what you mean by two-direction. What's your use case for this? Do you want to use it as a meter device? I'm not sure how accurate it works because a real Victron system requires a Modbus / ethernet meter for a reason.

[Brakelmann]

Two direction means it counts the energy exported (Export Total) and consumed (Consumption Total).
I have a second meter which only counts the created energy of the PV-System.
So the difference of energy created and and energy exported is the energy I used myself directly from the PV System.
As my PV System is from 2010 I get paid some extra cents for the energy I use directly.

Hi,
this is the output of my tasmota:

The JSON-data is:

{
"StatusSNS": {
"Time": "2024-02-07T03:24:39",
"ENERGY": {
"Power": 256,
"Total": 682.7129,
"Supply": 56.125,
"Voltage": 235.8,
"Voltage_L2": 236.3,
"Voltage_L3": 236.7,
"Current": 0.98,
"Current_L2": 0.28,
"Current_L3": 0.04,
"wirkleistung_l1": 225,
"wirkleistung_l2": 30,
"wirkleistung_l3": 0,
"phase_angle_L2_L1": 124,
"phase_angle_L3_L1": 241,
"phase_angle_L1": 2,
"phase_angle_L2": 298,
"phase_angle_L3": 270,
"Freq": 49.9
}
}
}

Is it possible to get the power for all three phases shown separetly in victron web-ui?

not at the moment with the existing code

I'll keep this in mind and implement it as we have done with the HMT series (3P PV inverter).
