ESP Easy Mega: Stromcount, more values?

#1 Post by B.Stromberg » 17 Oct 2020, 00:30

Hi Folks!
I successfully installed Mega on an ESP8266 Wemos D1 Board.
I am using the Board to count the impulses of me Power Meter SDM72 (S0 Port but no Modbus).

All works like a Charme but i wish to have more Values in the Interface, like Power Yesterday, Power Month, Power Year in kW/h.
All should be also transmitted via MQTT.
I come from Tasmota, but Tasmota Firmware dont work well at Counting, so i changed to ESP Easy.

Can anybody give me a hint how to add this Values? Or does anybody have similar already and would be so kind to give it to me?

Well there can be upto 3 or 4 pulse counters in ESPEasy.
On an ESP82xx there aren't that many free GPIO pins capable of this anyway, so the software limitation of 4 of those per ESP isn't really a problem I guess.

A very recent addition is the 1-wire DS2423 counter.
I have not used it myself, nor implemented the plugin. But maybe that's something that could be useful here?

oh...
i think this is a missunderstanding.
I dont want to add more Devices...

The existing one only counts the Pulse of the Power Meter. 1000 Pulse are 1 kw.
There is no Option to store this for hour, day, yesterday, month, year...

At Tasmota you have such Informations at the Webinterface of the Wemos.
But with Tasmota i have many misscounts at same Hardware configuration like with ESY Easy... I have no Plan why, so thats why i want to use ESY Easy :)

Ah OK.
Well you could create a dummy task in which you can store data (via rules)
The idea is that task values (incl. dummy tasks) are kept during a crash/reboot as long as the unit remains powered.

See the command taskvalueset: https://espeasy.readthedocs.io/en/lates ... skvalueset
And an example to compute water consumption (similar to what you're doing): https://espeasy.readthedocs.io/en/lates ... onsumption

Thank you!
That looks somehow exactly at what i am looking for. Tasmota do same with the script function in the Web Interface.

Sadly i am a Noob about scripting :(

Have really nobody done Rules for Counting Power Meters already? Sure its poor to ask about and not doing it myself but it can save me a lot of Time and Frustration, coz i am completly new at it :(
The Ferrari Meters are very popular and to Count via Optic Counter. But it Rules i think it dont matter if its Counting by Optic or by S0. The values are in the Counter already.
I also tried to find via Google but no success till now :(

Other Question:
Is it possible to publish the Time (Counter Value) at a local URL?
I need that to send it to the SMA Portal of my Power Inverter.
It should include the calculation in Watt already.

Example:
The Counter shows 4592 Counts. To Calc the present Power in Watt it looks like this:
3600/%value% (Counter) *1000

This Value i need at an IP in my local Network

Is that possible?

Yes it is possible to send the values and also to apply the formula in the task itself.

But I guess it is better to have them computed in the rules.
Right now I don't have time to help writing those rules, but maybe someone else can already help you until I have time for it.

I was searching around but found nothing :(

is it possible to copy the value "time" to a "folder" at the ESP?

So i could see ONLY THIS alue by typing something like that into the Browser http://192.168.2.235/cm?cmnd=Status%208 ?
