Energy meter with 3 tarifs

[chello]

Hi.
I would sugest to create energy meter device with 3 tarifs. I need that for energy consumption control in G13 Tauron tarif. Maybe just a small modification P1 meter would be enough - I don't know how do it.

I agree with this request, some of us need more sophisticated electricity tariffs.
Beside simple "peak tariff" and "off-peak tariff" often there are other rates, like:
'morning peak'
'afternoon peak'
'daytime peak'
'nighttime off-peak'
'24/7'
'other hours of the day'

I have a tariff with three different rates, and I'm pretty sure I am not alone here. Tendency is to more complicate our electricity bills...
How can we address this ? Adding more fields beside T1 and T2 should be not complicated ?

You can always load the tariffs yourself onto a separate device and then do the multiplication using a dzVents script to get your costs.
I do this for my hourly tariffs (although today the enever setup can do this?)

ok.. but with this approach I can also just go and use Excel spreadsheet and do my calculations there
It will be not integrated with anything, no graphs, no Domoticz reports, not visible in energy dashboard.

Having support for more that just 2 tariffs (T1 & T2) is crucial to keep Domoticz flexible and still user-friendly.

I have a dynamic tariff that changes every hour.
As long as you can create a device that has the actual price, you can specify this in the settings/meter under '(Dynamic) Price calculation'
Works quite nice actually
I set Domoticz in 'simple' mode, because I don't care anymore about T1/T2/Tx
The only thing I care about is the realtime graph, and the day/week/month/year and price

Ok, interesting. As long as I could use 'dynamic tariff' to accommodate my T1/T2/T3 I'm ok with that.
But TBH, I dunno how to setup this.. is it available only from recent Domoticz version ? I dont see such settings in my deployment (Im trying to avoid upgrading as long as possible, every time Im upgrading I have issues with something :/ )
I'm using my own plugin to connect to DDS238-7 (3phase meter) over modbus, so I will have to add support dynamic tariff, but this should be not a problem.

Dynamic prices is indeed introduced in latest releases 2024.7 I believe.
See wiki for basic instructions https://www.domoticz.com/wiki/Applicati ... alculation

You can create a dummy custom sensor and fill that with the current price. Then use that dummy custom sensor to calculate the energy costs (electricity and gas).

Maybe you should update more frequently....

There is also a backup made before upgrading, and you could also make a complete backup of the folder, so you can easily restore if needed
