Super weird. Guess I have to fetch my own HP2019 to try and recreate what happens there

Looking good, Robin!

Looks great! Is the plan to get flowcards/logic cards with the forecast for tomorrow in kWh? I primarily need tomorrow’s forecast in my flows.

Definitely! Focus mostly has been first to get usable forecasts. Next up is using forecasts in flows.

My end-goal is to make PbtH more a HEMS. Day ahead pricing is already in. Batteries are already in, PV is now in. Next up is EV and home usage prediction (the most difficult one I think).

But this is really still far on the horizon. PV should run stable first.

The graphs look better today. A reasonable forecast already on HP’23. On HP’19, a small bump between 17:00 and 19:00. The output power is being plotted correctly today. So I’ll just put it down to a hiccup for now. It probably has to do with the devices being switched on at the end of the day. In any case, it looks very promising. I am going to remove the summary for the PV. Having two things tracking exactly the same thing is, of course, a bit nonsensical.

I will make a new Virtual Device “SMA Datamanager M”. Now not only with power (W) but also energy (kWh). All this for a more correct solar-prediction.

Predicted Learning-problem: I’m dimming with netto negative prices (0,018-0,018).

Inverter’s output seems to be capped to 600W max?  
You could compare that value in the insights graph of the inverter itself, to see if it’s the device or the PbtH graph.

Here they’re pretty similar:

Question, when will the solar forecast be updated? Midnight? And idea, prevent the value from being lower than 0. With an external kWh meter you also measure the “stand-by” consumption of the inverter. You will then see the graph dive below 0. Perhaps has a negative impact on the prediction. Another thing, today the value of the PV stuck at 50W while there was no more production.

PbtH solar takes the realtime power data from the source device, just averaged a bit to smoothe out transient spikes.

The power forecast you see is the product of radiation forecast \* PV distribution model

The radiation forecast is updated every 15 minutes 24/7, based on a number of weather models. The PV distribution model is trained continuously/real time, plus every night around 1am it will fetch 14 days of Homey insights to calibrate the model.

PbtH takes whatever your source device reports.

So the prediction should improve around 1:00? Because right now the graph only shows a peak of 9 Watts between 17-19h on the HP’19. For tomorrow’s forecast.

Then I think we have a small bug after all. If I overlay the kWh meter and the Solar Forecaster, I get this image.

 ![Scherm­afbeelding 2026-03-13 om 22.14.34](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/d/9dc052a102f9f0497f7a7c6c4ffdd0832854e961.png)

Reboot both systems?

\*edit

Hmm, I found something. On the HP’19, the power is registered twice: positive and negative. Possibly a result of the beta test. I’m going to ask Jeroen about it.

Nice! Love the this possibility and tried it. Would it also be possible to use a variable for the time after “and”? Now it is only possible for the and .

After looking into what might be going wrong with my kWh meter with @Jeroen_Tebbens for a while, and finally removing and reinstalling the kWh meter and the Solar Forecaster, it seems that it is now working as desired. We will just wait and see what happens next.

 ![image-5](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/8/08e0dd2bdae3af2597a70b269c03052d3b83df23.png)

I identified this as an artifact from left-over deprecated power capabilities from older Homey firmware versions. In the next release I ignore those capabilities.
