Thanks Dick. to note, it has been running pretty smoothly on this side recently, so already very happy with it. getting it from the web API will hopefully only make it more reliable and robust. thanks! ---

Thanks for your kind words Patrick. On my side it’s also running smoothly. I have a feeling that too many requests to the ECU will make it to stop communicating. I now have a 5 minute interval and a start and stop depending on sunrise and sunset. The downside of the web api is that with a short polling interval you will reach the maximum api calls pretty fast. There is a possibility to pay for an increased amount of calls, but I’m unaware of the costs. ---

Device just became unavailable and the app no longer exists in the home app Store…. @Dick_J something happened? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/d/1de9e4d69d6dea38d9cfc88cadeb6a1a598836ef.png) Aah, so that is for the normal version. the test version still functions 😉 Only thing is that the tag: “when power changed” is not available in the test version, ---

It’s still there. The thing is that some flowcards you only see when selecting the device in the ‘apps’ column on the left. Maybe I can change that, I have to look into that ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/2/7206efa458a10850c6376c806e38486f218233f0.png) ---

I moved the cards to the list on the right. Downside is that the ‘original’ cards do not exist anymore and you will have to repair your flows ---

I see al lot of crashes, can somebody send me a diagnostic report? At my installation it’s running fine, so I don’t know what’s causing the crash. I use Copilot sometimes to write the code, but last week it messed up a lot of code 😢 I thought I had fixed things, but obviously not all/ enough. Maybe I’ll roll back to an older version. ---

Hi Peter, thanks. I also don’t have any problems. It could be just one user, but I doubt that. I saw that you only use the ECU data. It’s possible that the error only occurs in the web application. Today, 100 crashes. A new milestone 😞 ![IMG_4241](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/4/24be49612887d3309fe4ec00d4b8648ac9e6e24c.jpeg) ---

Maybe I can help, it is really strange app was working and now for the second time it mentions application unavailable and when I got to the store link it is gone as well. When I click the old app link from this forum post I can install it again and it works again. Needed to do this now two times already. ![IMG_9199](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/c/7cc11ba4da15caaf423a7c997ed272b555126cf3.jpeg) Report: 31633088-1fe0-47b6-8662-f5e458306dfa ---

exactly the same here. Looks like it happend both times though at an app update. Running smoothly for the rest. ---

Hi Niels, that happened to me as well, I turned automatic update off and than you don’t have any problems, you only have to update manually. It seems that the automatic update installs the regular version all the time instead of the test version. Best regards Peter. ---

I install the app in a different way, so I was unaware of this. I finally found an issue with the ECU triggers, when an error occurs or when the power changed. I released a version where this should be solved. [APS app v1.3.9](https://homey.app/nl-nl/app/nl.dj.aps/APsystems-Solar-Panels/test/) ---

I had changed the code to be more efficient. The ECU has to be polled once for information about the inverters and firmware and once for the generated power. I combined that, which led to the ECU becoming non responsive. So I changed it back. Also added a flowchart to reset the web polling counter, for instance at every first day of the month.

Hi Fellow Homey’s, I also have the AP Systems ECU. I succesfully installed the app and I added 2 devices: the AP Systems ECU and the Solar panels. I don’t understand the polling settings. I tried to change them a few times and now I get warnings that I am going over the 1000 max pollings in a month soon. I have these settings: This is the ECU: ![thumbnail_IMG_1093](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/8/b898782f4dd473409f3a8cbefe47d8b673093e7f.jpeg) This is the solar panels: ![thumbnail_IMG_1094](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/b/2b7050608c644fc62353b41e3019d4ebbb0b8539.png) ![thumbnail_IMG_1092](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/8/d86903ba658d2e318412aaed1f1f5b455e494f0c.png) Can someone please advise me what I should put in the settings of the ECU and the panels.

Hi Wouter, I see in your settings page that you starting pause at 7:00 and ending 17:00 so whether Sun is up your data is on pause, you should set start pause at 17:00 and ending at 7:00. Best regards Peter. ---

Thanks! That makes sense. And should I only put the polling in the ECU of also in the solar panels device? ---
