Can you please describe your issue more precise?
Thank you in advance.
I post json file for simulatorapp but tell me āUnable to get Response: A Singleton Component for PID [Ess.Power] is already existing!ā
What are you trying to do?
What you posted is clear for sureā¦
ā¦ if somebody else is willing to look into the magic glass bowl go for itā¦ i dont know what you are trying to do
It is indeed not very clear what you are trying to do. All I can say is that there is a singleton component with PID āEss.Powerā and Component-ID ā_powerā, which is automatically activated. Maybe, from the error message, you are tring to activate a second one?
We canāt see your full Json-RPC request in the picture, it would help if we can fully see it.

I have the same problem, trying to follow the instructions for creating a simulator App at openems/io.openems.edge.simulator/readme.adoc at develop Ā· OpenEMS/openems Ā· GitHub but it seems this Ess.Power with id _power is created on run.EdgeApp. But I havenāt specified any Ess.Power in my JsonRPC so I guess that the _simulator tries to create a new one, but fails due to there already being one.

Iāve the same issue.
For now I fixed it by uncommenting the following lines and configure the existing Ess.Power controller manually (via the Apache Felix Console) to disable Enable PID Filter. This works without any side effects for me now. I also had to disable the cycle configuration, as I had an issue with that. I configured the cycle configuration manually and set the cycle time to 0.
Currently these are my changes to make the simulation working (theyāre just a workaround for now, not an actual fix Iāll publishā¦):

Iām currently working on fixing this, but had some follow up issues Iām currently working on as well (caution - still speculative root causing: cycle configuration is not updated properly resulting cycle thread hangs in await state (is a bit of a flaky bug, but happens more often than not); component creation/retrieval via osgi not working for everything in the simulation setup, e.g. time of use controller). I hope Iāll be able to publish a pull request for this next week.

Iāve created a merge request to fix the Ess.Power issue. Took a bit longer than announced, sorry for that.
When I find the time, Iāll continue to look into the other issues Iāve mentioned (cycle time issue for the simulation)
