LPC failsafe write fails

[heavyweight87]

Hi,

When writting the failsafe duration or limit as an EG I get the error on the CS side:

update failed, likely not allowed to write

I cant figure out why this happens - any idea?

I am using WriteFailsafeConsumptionActivePowerLimit and WriteFailsafeDurationMinimum

BTW errors are sent to the debug log.... maybe its worth adding an error log type as well?

Thanks!

Did you initialize the CS data storage using the available public methods?

These kind of errors are send on debug on purpose for now.

I would need an actual log and code example to say what is happening. The above mentioned is the most likely cause. Also the version of the libraries are relevant.

Its with the latest version

Init storage how? Sounds like this is probably it...
Could it be that I should call SetFailsafeConsumptionActivePowerLimit for example, on the CS side?

Setting the consumption limit works if that helps

I assume latest version is the latest release. There the default is to not allow write.

You can either use the latest commit on the dev branch, which changed the default, or you can call SetFailsafeConsumptionActivePowerLimit to set changeable to true.

In general you should initialize all data structures in a controllable system to your desired default values. The stack can't know these. And always do this before h.myService.Start() is invoked.

Yes I meant release.

I have something like the following, but it didn't seem to help

// Adds the use cases to the service.
func (cems *Cems) addUseCases() {
	localEntity := cems.service.LocalDevice().EntityForType(model.EntityTypeTypeCEM)
	cems.uccslpc = cslpc.NewLPC(localEntity, cems.OnLPCEvent)
	cems.service.AddUseCase(cems.uccslpc)
	cems.uccslpp = cslpp.NewLPP(localEntity, cems.OnLPPEvent)
	cems.service.AddUseCase(cems.uccslpp)
	cems.uceglpc = eglpc.NewLPC(localEntity, cems.OnLPCEvent)
	cems.service.AddUseCase(cems.uceglpc)
	cems.uceglpp = eglpp.NewLPP(localEntity, cems.OnLPPEvent)
	cems.service.AddUseCase(cems.uceglpp)
	cems.ma = ucma.NewMPC(localEntity, nil)
	cems.service.AddUseCase(cems.ma)

	//set defaults
	cems.uccslpc.SetFailsafeConsumptionActivePowerLimit(1000, true)
	cems.uccslpc.SetFailsafeDurationMinimum(10*time.Second, true)
}

This is done before service.start() obviously

Please try the dev branch. In my test it works there

Thanks it works great now!
