From where does this app fetch the prices? Nordpool seems to want a lot of money for API access, and scraping isn’t allowed, so I guess it isn’t from Nordpool. Entso-E has a free API, but prices needs to be converted to NOK, so fetching the current rate NOK/EUR is also necessary.
This is a really useful app, and I hope it will stay around and continue working indefinitely.
I’ve been using the new functionality of updating with energy instead of power, and it seems to work fine. I’ve been testing with two Strømregning-devices, one being fed power values and one being fed energy (source device supports both), and the one getting power values seems to accumulate slightly higher numbers than the one receiving energy measurements. The difference isn’t large though (around 5% in my test).
Ok, but the average marked price is different every day. Do you update this every day at midnight?
Edit:
To clarify, I want to see if I can beat the average spot price for the day. Like today, the average spot price is 195 øre, but there are a few hours that drag up the average. So if i use most of my power in the cheaper hours, I should be able to get a lower average. And that is the information I’m interested in.
For instance: I only keep my water heater on the 12 cheapest hours of the day. This should bring my average price down. But it’s hard to calculate how effective it is.
Det hadde vært supert om du kunne lagt til en label for gjennomsnittspris gjeldende døgn. Og kanskje en label for strømpris neste time, slik at man kan benytte denne timen til oppvarming, hvis neste er høyere.
(Kanskje også en med laveste og høyeste strømpris dette døgnet?)
Sorry for the Norwegian post. Translation:
It would be really nice if you could add the following labels:
average price for current day
price for next hour, so that you can use this hour for heating.

I’m updating a “Strømregning”-device with energy from a device that provides this. However, this device apparently reported a spurious energy meter reading that was much lower than real. I don’t know how this could have happened (it’s a Z-wave device), but it totally ruined the stats for costs:
“Strømregning” received this spurious lower energy measurement, and when it went back to normal, the positive difference was calculated as instant consumption. While the spurious reading isn’t Strømregnings fault, my stats are now ruined (which is very annoying).
It is probably best to use power instead, because then these things can’t happen.
Edit: If I export the energy measurements as CSV, there are two erroneous readings recorded by Homey:
I will say that perhaps “Strømregning” should disregard any energy readings that are lower than the current value, effectively filtering out spurious readings like this. Now, there’s of course no guarantee that there will not be spikes going the other way as well, so perhaps best to just stick with power, at least spurious values (if quickly replaced by normal values) isn’t going to ruin the cost calculation.
Thanks for a really useful app.
Is it possible to manually add values to bring cost and energy consumption up to date for monthly and yearly calculations? If not, is that something you might consider implementing?
Hi, i was wondering if it would be possible to add average power usage per hour, per month, and per year? I have a flow for it now but would be great to have it in the app.
Pardon me if this has been previousely answered. But Tibber and your app do not agree about the energy cost? They both use the same price, so what can be the hickup?
Can not show the comparison, as I am only allowed to post one embedded image. But Tibbers cost at the same moment was 3,31 kr incl VAT.
