Nordpool electricity prices plugin

[tjabas]

So I have been using a nordpool plugin which I found here, it has been working great but now when I have upgraded to bullseye then it doesn't work anymore, is there any other plugin I can use to get the electricity tariffs into domoticz?
I'm from Sweden.

Thanks

Did you notify the plugin ownrf ur issue?
Did you also upgrade th python modules the plugin perhaps needed?
Do you have a link to. GitHub repository?

Yes I have talked to the writer of the plugin and he didn't have any plans of fixing this issue, the issue it that the plugin doesn't work with the upgraded phyton, I will look for a link to github.

Here's the link:

I suppose the modules install goes wrong? This is because of the new python virtual environments in Bookworm.
Did you try adding

Code: Select all

--break-system-packages

to the install command?

So use

Code: Select all

sudo pip install -r requirements.txt --break-system-packages

Edit. You upgraded to Bullseye. Did you reinstall the plugin requirements? As they could be changed due to the upgrade of your OS.

Certainly! It seems like the Nordpool plugin might not be compatible with the Bullseye upgrade. You can try using the "domoticz-emoncms-plugin" for fetching electricity tariffs in Sweden. Make sure to update your plugin list and configuration settings accordingly.

If you are Dutch you also could switch to the Enever hardware gateway, https://www.domoticz.com/wiki/Enever

Else you have to find the issue. It could be anything from noordpool stopping or switch API or python update issue etc

[tjabas]

i also tried with an older backup version of domoticz but the problem where there to, so i guess that there has been a change at nordpool, is there any other plugin that works with nordpool?
i live in sweden.

[JBN]

@tjabas, I am curious. What are you using the plugin for? And do you use all the counters it creates?

I was playing around with https://www.elprisetjustnu.se/ yesterday since they have the data available online too.

[tjabas]

Im using it to turn on and off some Electrical components when the price is low, the water heater, charging my car, turn on and off heatpumps.
So its kind of hard that the plugin doesnt work.

[tjabas]

Is it possible to get the plugin the fetch the prices from. The link you provided?

[JBN]

I have not tested this thoroughly but if you want you can try: https://github.com/j-b-n/sweden_energyprice

Let's debug together, I have sent you a PM.

[sumitrathore]

It looks like NordPool changed its API. You can try using the 'domoticz-emoncms-plugin' or find another plugin that works with the new data.

[sumitrathore]

Hello everyone,
Has anyone found a reliable plugin or method to integrate with the new NordPool API? I’m specifically looking for something that can work seamlessly with Domoticz or a similar home automation platform.

Regards,
Sumit.
