Thanks @Dick_J, So my version is/was the correct version. Point is the difference in firmware, I managed to implement a fix, have contacted APSystems yesterday already. Thanks for the help. ---

How does your fix look like if I may ask? ---

Sure, first you have to reboot at 11PM. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/2/12f1776575108aa7efba20295e0cb7d5b6b38d2a.png) Then the following at 5AM/sunrise: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/c/8c1f220a5203891c4c3fe4c465a0470e894252a7.png) This works to avoid 0W after the night on firmware 1.12.3, no problems on firmware 1.12.2t on the EZ1. ---

Thanks! That’s really weird though. If it works after a reboot there doesn’t seem to be a change in the APSystems Local API, but either the converter or the Webserver doesn’t seem to survive the night. Would you mind testing a bit further? When the EZ1 doesn’t show values in the app, could you test the command in a Web Browser I gave you again? Try also this one please (when it **doesn’t work** ): http://{YOURDEVICEIP}:8050/getOnOff Oh, and also try without a smart plug please. Just to rule out everything. They could’ve changed power management or something. Maybe we can find an easier fix. 😄 ---

Will test upcoming night and let you know. ---

So I disabled the flows, kept it behind the plug, no timer on the plug and ir was still working this morning 🤷 Will let it be like this next night to see what happens again, the night after that I will remove the plug and test again. ---

Is it still working? ---

Hi SGO did you try ptp on the ECU-R. That mostly solves the problem. Regards Peter. ---

Hi Peter, thanks, but I don’t own an ECU. I have two EZ1 like @StephaneDN but with the old firmware. 😉 Thanks anyway though! ---

Hi Steve oké didn’t know that but does the power down from the switchboard do the trick. Good luck Peter. ---

I would also be interested in the same option. You can indeed have APsystem switch the inverters on and off, but you can only have that work when you pretend you don’t pay a surcharge.. but that also means it switches off to soon .. hence being able to control that via homey would be amazing and highly appreciated. UPDATE: 7-8-2026 it’s indeed possible to copy the decimal point (or complete value) and paste. And that worked for some time, but recently, it seems after I’ve added the EMA homey app, I lost that info in the original EMA app on IOS… that said, the original IOS app had that issue before.. When using it on the 0 value, it worked, but would switch off the inverters sooner than I would have liked. I have an ECU-R. ---

Also, I’m very new to the Homey system and tech all together, so clear instructions on how to set such thing up would be highly appreciated. ---

Hi Laurens, at this moment in time, there is no way to switch the inverters off/ on. It is most likely done by APsystems through there servers. As for the option in the app, there was this response on June 15th to my remark that it didn’t work well: _### **APsystems Support EMEA** [support.emea@apsystems.com](mailto:support.emea@apsystems.com)_ _Good day._ **Due to bugs in the “Dynamic Tariff” function, please do not enable this function for the time being.** _ **Also please check if all relevant text fields for settings in the EMA APP have been cleared.** _ _As soon as the problem is resolved, we will send a notification to all affected users._ \*We sincerely apologize for any inconvenience or frustration this feature may be causing the customers. \* _Kind regards,_ _ **EMEA, APsystems Technical Support Team** _ It has been quiet since, I’ll send them a reminder. Meanwhile I was trying to connect through Modbus. That was easy but it seems that they’ve not implemented the Sunspec fully. I raised a question for that, but also silence there. If it ws implemented right, then switching the inverters off and on would be possible. Best regards, Dick ---

Thanks Dick, I’ll wait and see. I’ve also been doing some reading and the ECU-C from APS has a zero export function, so I’m considering upgrading to that ECU instead. But still doubting whether the extra €275,- will pay itself back in reasonable timespan… ---

Hi Laurens, I have the same idea about the ECU-C. But it also requires a mod of your fuse box; 6 current transformers and a circuit breaker for the ECU. From what I’ve read the ECU-C is not protected for overcurrent on the voltage inputs. And though I could do this myself, the fuse box gets pretty crowded.
