Power plug script need big help

[Fredom]

Dear forum members,

I have a zigbee power plug (see photo).
I would like to monitor consumption with this.
Now I found a script here on the forum that does exactly what I want.
I have modified a few things to suit my need.
Unfortunately I can't get the script to work, I've been trying it out for days.
To test I use a 15 watt bulb.
Can someone please help me with this.
I have put the IDX numbers on the photo
Everything with (--this is new) I have adapted myself

Script

Code: Select all

-- This is a dzVents-script for monitoring a machine. It will send a notification when the machine has finnished its run. The message will include duration, powewr used and the cost.
-- I found the script on the domoticz forum, created by Ragdag and I wanted changed it to use Telegram and also added duration and some other features.
-- How to set it up? Find all comments with SETUP and update to fit your needs. For test, use a lamp as a load and set MachineStandbyUsage to 1 and MachineStartUsage to 3. Easier than starting and stopping your washer ?
-- If my suggested parameters dont work with your machine, start the machine and look in domoticz to see the power used by the machine in the beginning of the cycle and in the end.
-- Regards, Jens M nsson

Hi HvdW,

Thank you very much for the quick response. I'll get to work on it right away and let you know if this is what I want

[Fredom]

Hi HvdW,

Unfortunately this is not what I want.
What I want is a script that starts, resets everything, then starts measuring number of watts, the price total and running time then stop.
The script in my earlier post does that if I understood it correctly.
Unfortunately I can't get it to work

[waltervl]

What device did the Zigbee gateway add to the power plug? As that should be a device like your 512 and that monitors everything you want Out of the Box. No need to script anything...

What Zigbee Gateway do you use? Zigbee2MQTT with plugin or MQTT Autodiscover? ZigbeeforDomoticz plugin?

What device did the Zigbee gateway add to the power plug? As that should be a device like your 512 and that monitors everything you want Out of the Box. No need to script anything...

What Zigbee Gateway do you use? Zigbee2MQTT with plugin or MQTT Autodiscover? ZigbeeforDomoticz plugin?

Hoi Walter,
I am using Zigbee2MQTT with plugin v.1.19.1 (zStack12 20201127) and usb Texas_Instruments_TI_CC2531_USB_CDC___0X00124B001CCE0853-if00 -> ../../ttyACM0.
Zigbee has created
513 switch,
512 power,
514 current,
515 volts

[waltervl]

Did you already look at the log and then the report page of device 512? as it contains all information. It only cannot differ between day and night prices. See also wiki https://www.domoticz.com/wiki/Managing_ ... ice_Report The example there is from a P1 smart meter device but power device has something similar.

@Fredom
Maybe you can find some inspiration here.

Did you already look at the log and then the report page of device 512? as it contains all information. It only cannot differ between day and night prices. See also wiki https://www.domoticz.com/wiki/Managing_ ... ice_Report The example there is from a P1 smart meter device but power device has something similar.

Hi walter,
Glad you want to help me with this.
I took some pictures of the logs and the switches.
Which I hope the script can work the way I want it to.
Unfortunately I can't figure out how to process something like this from the log in a script.
I am now able to make very small adjustments by trying a lot. At Cost test (947) there I would like to see the cost of the measurement

Hi Walter,
This is the switch of the smart plug.
Ik was hem vergeten erbij te plaatsen

I really do not understand what you are trying to report. The cost of the switched on? Per time it was switched on?
So something like
20-01-2022, 15:01 - 15:15 , 125 Wh, €0.05
20-01-2022, 15:45 - 16:50, 1000 Wh, €0.40

As this can only be reported in a text sensor.

If you just want to see the costs per day, month, year they are in the device report as you can see in your screenshots. As you only have 1 month of available data in year 2023 there is not much to report yet. What about year 2022?

Hi Fredom

There is enough information.
I suggest you to take a look at this topic.
From there you will be guided to huizebruin.

It takes a bit of studying a bit of patience, but I'm shure it will bring you to what you want to achieve.

Hi walter,
What I would like if possible.
Switch (513) on then reset (512) and start measurement (512). Stop (513) Report duration, watts and costs in a report to a text sensor and Telegram.
If I understand the above script a bit then that should be about it.
The day and night cost is not that important but would be nice if possible.

Hi HvdW,
Thank you for thinking along.
I've also seen what you suggested on this forum, but unfortunately it's not what I'm looking for and want.
I already have a script for my solar panels that works great.
It is now about a power plug that I can always use somewhere else to do a measurement. Then I want to know the duration, number of watts and the cost in a text sensor and telegram

So the script should be triggered on device switch 513
if switched On, remember the time it is switched on and save the current Wh count (.WhToday) of device 512
If switched Off get the current Wh count (.WhToday) of device 512 and the delta in time of switch 513 and the delta in Wh count of device 512 and the delta Wh * costs should be reported to text sensor and telegram.

I think I gave you enough clues now to program this.

Hi walter,

Thanks for the thoughts and tips

[HvdW]

What I wanted to show you is this.
My Shelly plug script.
The other one I showed is the script to count electricity usage and return.
These are examples on how to handle things.
Read, understand and combine and you'll end up with what you want to achieve.

Hi HvdW,
I totally understood what you meant. Only I'm not a programmer this will never work unfortunately.
I can make very small adjustments by comparing a lot with other scripts. Then sometimes it works to get it working.
I had hoped to get the script in my earlier post working. But I have now also seen that if you read the log of a switch, you can also see what I want. I have to calculate it myself. Then it should be like this. Thank you for your effort.

[HvdW]

Read this carefully.

I learned a lot reading other people's scripts.
