Spot price as export price

[Belaial]

Hi,

I'm wondering if I could be missing something easy here, sorry if I have, I have tried to configure the "Price configuration", the scenario I am trying to achieve is the following.

Import = Static price
Export = Spot price

I have had no issues to configure a static import price but I see no way of selecting the import price as spot price, am I missing something or is this not currently implemented?

Reading here https://github.com/UtilitechAS/amsreader-firmware/wiki/Price-configuration it seems it's not to be possible currently, maybe this could be added in the future?

Hardware information:

• Country: Finland (Belonging to SE3 price region)
• Meter: Kamstrup
• Encryption enabled: No
• AMS reader: esp8266
• M-bus adapter (if applicable):

Relevant firmware information:

• Version: 2.3.7
• MQTT: Yes
• MQTT payload type: Home Asistant
• HAN GPIO: GPIO5
• HAN baud and parity: 2400 8N1
• Temperature sensors
• ENTSO-E API enabled: No

Thank you for the enhancement suggestion, we will consider such enhancement for a future update.

We should update the documentation to be more clear, but the spot price is used unless a fixed price is set.

This is my current config regarding price

So, as I see it I have not set any fixed export price? Yet my graph show 0.00 €/kWh, should it not show current spot price if I understand your post correct?

Interesting, if I check in Home Assistant I do see a varying export price

I guess it just does not show in the GUI of the AMS reader?

Followup question, I assume this will work correctly even if no spot price is configured under Price configuration.

For every kWh I produce the power company takes 2,5 cent as a "transfer fee" of sorts, so I just add this to export price like so

I assume after adding this it will calculate spot price - 0,025 = export price ?

I will follow up this in Home Assistant, bad day today tho as the price is basically a flat line around 0....

Correct :)

I guess this is why the price in the export gauge shows 0.00? Probably currently it is less than 0.01? Let me know how that turns out.

Also, for NOK/SEK/DKK I have added subunit (øre) as an option. I guess we could to the same for EUR, so that when the price is really low it would show cent/kWh. Any thoughts?

I will follow the graph and see 👍 , currently it looks like this, I added the transfer fee around 10, that's why there is a big drop there. Hopefully the prices are better tomorrow so I can see how it works, I will report back in a day or two.

Please do if it's not to much work, it might be easier to read instead of 0.0255 EUR/kWh like it is now

Also makes it more consistent I guess, if other currencies shows (øre) and so on that also Euro would behave the same.

Good idea! 👍

Again the spot price has been close to 0 for 3 days now.... but the graph is moving so I assume it's working according to spot price - 0,025 = export price 👍

I guess updating the documentation to explain how it works if you don't configure a fixed price is enough, unless you want to make it even more clear but adding to ability to select "Spot price" in the drop down menus under price configuration.

I guess we can close this issue, unless you want to keep it open and close it when the documentation is updated @gskjold
