PLEG conditions checking if charger drawing less than 1W for more than 10 mins

Plugins & Plugin Development Program Logic (PLEG)
#1

Hi guys,

I’m really struggling with some logic, and unfortunately my plug in adaptor, since the latest firmware, doesn’t have a trigger available to detect the power, so having to use device properties.

So basically, what I’m trying to detect, is if my tablet_charger (ptblt_watts Tablet Charger[5]) is using less than 1W power, in which case, all phones, tablets and anything else plugged in, is fully charged.

Device Properties:
ptblt_watts Tablet Charger[5]
pTablet_Charger Charge Tablets[116] virtual switch to override

Triggers:
tBattery_Charger_On = Tablet Charger is turned on

Conditions:
cTblt_Watts: (condition to replace missing trigger)
ptblt_watts<1

tblt_charge_full:
(tBattery_Charger_on and (cTblt_Watts; NOW>00:10:00)) and !cBattery_Charger_StayOn and (tBattery_Charger_On; NOW>00:05:00)

cBattery_Charger_StayOn:
pTablet_Charger or (tBattery_Charger_On and tBattery_Charger_On;tBattery_Charger_off;tBattery_Charger_On<00:00:30))

To test, I’ve created some smaller conditions:

cCharger_Time_On: (check if charger has been on for more than 10 mins)
(tBattery_Charger_On; NOW>00:05:00)

cTablet_Charger_Test: (check if watts less than1 for more than 10 mins
(cTblt_Watts; NOW>00:10:00)

Currently :
cTblt_Watts = false
cCharger_Time_On = true
cTablet_Charger_Test = true

Not sure how this last conditon can be true, based on cTblt_Watts being false. Would anyone have any ideas? It’s causing my switch to turn on and off rapidly!

Thanks

A sequence expression “(cTblt_Watts; NOW>00:10:00)” does not care about the current state of the condition cTblt_Watts - just the timestamps associated. You are currently indicating if it was last < 1 WATTS more than 10 minutes ago. If you want to know it is < 1 WATTS NOW, AND that it went < 1 WATTS more than 10 minutes ago, that would be “cTblt_Watts AND (cTblt_Watts; NOW>00:10:00)”.

Your PLEG is pretty complex, and you have appear to have 12 (!) different actions that would either turn on or turn off “Tablet Charger[5]”, so it is going to be hard to troubleshoot.
