Nordpool

[JohanAlvedal]

Hello This seems like an interesting project. However, I have nordpool (tibber Sweden) as an integration in HA which delivers my electricity prices. Also has a Huawei inverter that communicates using modbus from HA. The question I have is if you can somehow get it in instead of octopus?

It would be nice to have these to work with Nordpool metric_octopus_import: 're:(sensor.(octopusenergy|)electricity[0-9a-z]+[0-9a-z]+_current_rate)' metric_octopus_export: 're:(sensor.(octopusenergy|)electricity[0-9a-z]+[0-9a-z]+_export_current_rate)'

I've already started getting some data into predbat, so it's looking promising.

sensor.nordpool_kwh_se3_sek_3_10_025 shows the current price and have all data current tomorrow and so on as attribute.

I think it would be easy to integrate this, it's almost the same as the Octopus.

Can you show a snapshot of the above from within HA in the Developer tools, States menu and I'll get it supported?

[JohanAlvedal]

[springfall2008]

And you want to use the values from 'today' as your import rates?

[JohanAlvedal]

Yes exactly and tomorrow if possible. Export sensor is an equivalent but without VAT.

One question, if I don't want to use the function to charge an electric car, can I then uncomment all that apply to the car?

Yes exactly and tomorrow if possible.

Export sensor is an equivalent but without VAT.

One question, if I don't want to use the function to charge an electric car, can I then uncomment all that apply to the car?

Just set num_cars to 0 in apps.yaml and predbat won't do anything with car charging

[springfall2008]

I've submitted a change to MAIN which should now read this format of data, just point your metric_octopus_import/metric_octopus_export to the sensors and let me know if it works.

[JohanAlvedal]

I'm not sure how? like this? metric_octopus_import: 're:(sensor.(sensor.nordpool_kwh_se3_sek_3_10_025)' metric_octopus_export: 're:(sensor.nordpool_moms)' or metric_octopus_import:

• sensor.nordpool_kwh_se3_sek_3_10_025 metric_octopus_export:

  • sensor.nordpool_moms

  And if there is anything else I need to do?

When I tried both options I get the same thing in the log in HA `s6-rc: info: service s6rc-oneshot-runner: starting s6-rc: info: service s6rc-oneshot-runner successfully started s6-rc: info: service base-addon-banner: starting

[springfall2008]

It doesn't look like you updated to the version on 'main'?

[JohanAlvedal]

ok but how do i do that?

[springfall2008]

Select the version from the select.predbat_update drop down menu.

This code actually ended up released now also

[JohanAlvedal]

it works but the price is not 100% correct, for example now at 21:00 the price is 0.02 Sek, but it shows 2.00, but perhaps it should be so?

[springfall2008]

What should the price be according to the data, is it out by a certain factor?

[JohanAlvedal]

the price from Nordpool is correct but it is shown in kronor equivalent to pound not pence. 0.02 SEK (1 GBP = 13.36 SEK 133.6 öre (pence). But maybe it should be? it is pence in import and export but in GBP in the far right column.

[springfall2008]

Yes it’s pence on the left and pounds on the right for the total

[gcoan]

the price from Nordpool is correct but it is shown in kronor equivalent to pound not pence. 0.02 SEK (1 GBP = 13.36 SEK 133.6 öre (pence). But maybe it should be? it is pence in import and export but in GBP in the far right column.

Predbat assumes all the prices from the energy sensors are in pence and produces the plan in pence. Just the total column on the right of the plan is pence x 100 ie GBP

Ignoring that the units are wrong for you, is the order of magnitude of everything correct?

I don't think we want predbat to start doing currency conversion but it may be possible to have a "display currency" setting or some Jinja post processing of the html plan to change the currency text strings

[JohanAlvedal]

Well, that's right, I'm satisfied, very satisfied, thanks for the help so far. Now it will be allowed to run for a few days, then I will work with the settings a bit
