Option 2:
More hours ahead with detailed price information. Now +8h is the max, but +32h would be great. Then I can create my own flows. At the moment there is no price information other than the highest/lowest price after +8h.
First of all, Robin, let me thank you for the great pbth app. It works great and I really enjoy it.
One small remark: is it possible to print the date somewhere visible/readable on the day ahead graph?
I’ve 2 reasons:
- the graph seems to be buffered in the homey app and I always need to refresh to be sure to have the latest
- I’m saving the images daily as some reference. Would be easy if they are labelled with the correct date
I am using this app for a few years now and it’s really great. The most important use case for me is to charge my car at the cheapest hours and to report on the amount charged, to keep an eye on what charging my car costs. This all works well, but I now have a new challenge because I bought a second electric car. So, in a few months time, I have one charger and two cars. Ideally, I would be able to see the energy totals per car. Both cars should be able to talk with Homey and based on that information, I should be able to know which car is connected to my charger. Could you implement something that makes it possible to get the totals per car? I was thinking of two potential approaches:
- Create two summarizer devices for the car charger and implement flow cards to pause and resume them. I could then resume the summarizer for the car that is connected and pause the other one. Potentially you could add a third summarizer to get the grand total which you never pause.
- For the summarizer devices, enable multiple counters, like A and B and use flows to switch between them. This would mean, that the device gets many more properties and it does not really scale.
The first option is probably the easiest to implement and would allow any number of summarizers for a device.
Curious to hear thoughts on how this could be done.
Trying to find a logic card that can define if the spot price in a specific time frame is x% higher or lower than another specific time frame. Reason is to determine if the price diff is high enough to charge the solar battery from the grid or not.
Picture 1. Current prices is one of the 4 lowest between 09 & 17
Picture 2. same logic will find the low price during mid day, but the price in the evening is to low to use any cycles on the battery…
If more than +7 prices was available i could calculate it from variables.
Any tip is appreciated on how to solve this
Many thanks for your kind donation @Hakan_Berg ! Much appreciated 
Concerning your question: The battery monitor of PBTH has special flow cards to optimize financial ‘profit’ with a home battery. Did you look at that?
Otherwise you could combine cards like this:
Hi
Which one of these do you mean?
I tried several versions of the flow card you suggested. The challenge is that the peak in the evening is normally quite short.
But the peak can be realy high, like double the price.
Then the next day the peak is very small, but i still find it with the 4 lowest prices after 15
Then it’s no good to charge the battery.
If there is one peak in the morning and one in the evening the average value is no good to find what i want.
I use your variables right now.
Take the actual price at 10:00+1h+2h, then calculate the average of that.
If the value at +7h is x higher than the average from the 3 values i charge during the day.

The home battery device. That has a linear solver to optimise profit for batteries. If your battery doesnt show up when you start pairing, I could maybe add support for your battery if I know what capabilities the battery app has.
Yes that. Play with the ROI trigger card and then check the graph showing when it will charge/discharge.
You first need to change the settings to match the figures for your battery.
OK
Thx
Woha, a lot of settings to figure out.
I have a Goodwe Lynx 16,4kwh battery, next week i will have 2x 16.4kwh. (2 stacks 16,4)
With a Goodwe ET 6,5kw VR.

If you can help me configure this i support you with again 
Thx Hakan
