I got it working! šŸ˜€ 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 isnā€™t 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. ---

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? ---

Iā€™m 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, Iā€™m in eventually Iā€™ve got it working and found the IP address inbetween all my devices Iā€™ve got the right one now šŸ˜Š and fixed the IP address in my Modem so that it wonā€™t change anymore.

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: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/0/c0a44bfee3c2048e41b491b410d4ccf969eb87e9.png) ---

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/ didnā€™t send any data. The lifetime data will come from the ECU, so that was displayed. Since also HA didnā€™t report anything, it must be something with the ECU. All inverters stopping at the same time is unlikely. ---

Iā€™ve added some more logging in the code, for diagnostics and released a new version. Now I hope Iā€™m 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 donā€™t see any information about the voltage. ---

I still have to figure out thingsā€¦ thatā€™s 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 šŸ˜„ 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 itā€™s running smoothly since. ![1000011929](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/9/d9d4644ed8e543a6eada04c2489d0adcfd031cad.jpeg) ![1000011930](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/4/b4d3d16cd3a2f19acbe62c5455e25558ee937879.jpeg) The only question Iā€™ve got is why I see the voltage drops because itā€™s hardly unlikely that that happened šŸ˜³ 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. ---
