Same problem, different day…
I would like to measure the total daily energy consumption in kWh of my phase 3. My heat pump is connected to this phase.
I have a Homey dongle that (unfortunately) only measures power in watts. And not meter power.
Using a flow, I send the watt value to a virtual energy summarizer. Which is configured with “source = watt”.
However, I am getting strange (negative) values for the total consumption per hour/day.
I checked the values being sent, and they are always positive (47, 50, 500, 47).
Does anyone know what I am doing wrong?
So, no news then.
Since Midnight, 15 minute prices are back. 
@Gruijter I set the home usage in the battery monitor to 0 W, but it still does not pick the better export price.
In the screenshot, the yellow line is the export price. The strategy seems to ignore the higher export price peak, while it does select the lower import price afterwards. Since home usage is set to 0 W, I would expect the export price to be considered directly, without any correction for household consumption.
Could you check whether the ROI strategy is actually using the export price in this case?
New version 8.9.4 is ready for testing: https://homey.app/a/com.gruijter.powerhour/test/
- Resolve missing prices issue
- Prevent battery provider flip-flopping
- Fix Homey overload on hourly updates
- General stability improvements
- Homey-api 3.19.1
This should fix the issues you reported @Geert1992 @Bart_van_der_Wolf @Jakko_Paadik
Will look at it with high hopes.
The hourly Homey overloads are an interesting mention I’ll be looking out for as well, although there could potentially be other things that could cause it, but I haven’t identified which. Would be great if this solves that as well.
Thanks! Installed allready and looking out for any anomalies.
