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?
Thanks! Thatās really weird though. If it works after a reboot there doesnāt seem to be a change in the APSystems Local API, but either the converter or the Webserver doesnāt seem to survive the night. Would you mind testing a bit further?
When the EZ1 doesnāt 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 doesnāt work): http://{YOURDEVICEIP}:8050/getOnOff
Oh, and also try without a smart plug please. Just to rule out everything. They couldāve 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 donāt own an ECU. I have two EZ1 like @StephaneDN but with the old firmware. 
Thanks anyway though!
Hi Steve okĆ© didnāt 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 donāt 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 itās indeed possible to copy the decimal point (or complete value) and paste. And that worked for some time, but recently, it seems after Iāve added the EMA homey app, I lost that info in the original EMA app on IOSā¦ 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.
Hi Dick, I realized Iāve responded to the wrong user

Also, Iām 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 didnāt work well:
### APsystems Support EMEA support.emea@apsystems.com
Good day.
Due to bugs in the āDynamic Tariffā 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, Iāll send them a reminder.
Meanwhile I was trying to connect through Modbus. That was easy but it seems that theyāve 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,
Iāll wait and see. Iāve also been doing some reading and the ECU-C from APS has a zero export function, so Iām considering upgrading to that ECU instead. But still doubting whether the extra ā¬275,- will pay itself back in reasonable timespanā¦
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 Iāve 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.
