I got it working! 
Just had to fiddle a bit with the IP address when switching from a wired connection to Wi-Fi. Somehow it then creates a different IP address and also a different MAC address (which isnāt the one shown on the ECU sticker).
Hi Steven, I just connect mine to the WiFi, which Ip adres did u use to get it working ?
Thanks and best regards Peter.
Hi Peter, the IP address would be different in every household. Look into your router for something like EMA
Look in to your router and find the IP with the namen ESPā¦.. That is the wifi ip from the ECU.
Tip: fix this IP in your router
Had a stuck app this morning. A reset of the app solved it. Will do a diagnostic next time when stuck.
Regarding poll time, I think official is every 3 minutes?
This morning, the app also stopt working on my Homey, but restarting the app (and the ECU) didnāt help in my caseā¦
Since yesterdayās update my power and temperature are not being displayed correctly.
After restarting the app, only the temperature is not displayed correctly.
Iām currently using the Home Assistant app, in addition to this new app.
In the Home Assistant app, I can also see the energy yield of each solar panel.
Is this something that could be implemented?
Hi Dick and Steven, Iām in eventually Iāve got it working and found the IP address inbetween all my devices Iāve got the right one now 
and fixed the IP address in my Modem so that it wonāt change anymore.

Thanks a lot for all your effort,

Stuck today ae well
Diagnostic before resetting the app:
92d3f616-dc2a-42ed-b47b-76fb03f9463c
And after a reset
69b5d046-2f62-4096-a02b-56d6c918a3e7
by the way, HA was also stuck:
I have to make adjustments in the software to get more info from a diagnostic report. For now I can see that the inverters were offline/ didnāt send any data.
The lifetime data will come from the ECU, so that was displayed.
Since also HA didnāt report anything, it must be something with the ECU. All inverters stopping at the same time is unlikely.
That should be possible, but for now I will try to get it working without errors and crashes 
From what Iāve seen, the ECU only reports every 5 minutes. I want to find a balance between retrieving data and putting the load on the Homey
982be4f4-a9d2-40f9-9a1c-a69bfb278648
This one the HA system is actually sending data., and that was correct wrt to the APS app.
Iāve added some more logging in the code, for diagnostics and released a new version. Now I hope Iām able to see the data coming from the ECU and see why the power is zero, or in another case, extremely high

Hi Johan, if the temperature is correct, are you saying that you produced 72kW at that moment? It seems a lot, unless you have 180 solar panels.

Hi Dick, I have 12 panels and a maximum of 4000W. The information is incorrect, but it works fine after restarting the app. However, the temperature information continues to be incorrect. I also donāt see any information about the voltage.
I still have to figure out thingsā¦ thatās why I changed the code so the diagnostics have more content. I only know since yesterday what the result is when you send a diagnostic report from the app. Remember this is not my work, just a hobby 
What type of inverters do you have?
Hi Dick, here an update about my system, since 12 this afternoon I deleted the ECU-R from Homey because it was still stuck and added it again, now itās running smoothly since.
The only question Iāve got is why I see the voltage drops because itās hardly unlikely that that happened
And what is the graph Energy usage mean because it should only generate electricity not using it, or am I wrong.
Thanks again and best regards Peter.
