I'm not too familiar with how the RRD engine works, but surely the last value it has is the one it got from the OpenRemote Sensor?
So have you tried displaying that sensor?
(At least that's how I show current and accumulated Velbus energy data from a VMB7IN)
Cheers,
Stuart
Hi Stuart,
That's one complex way if getting a reading.
I really wish I could help you.
A Velbus input module could count the LED pulses and give you the answer, but they really doesn't help you right now.
Good luck,
Stuart
I'd use rules to achieve this: -
Convert pulses to watts
Push value into in memory (virtual) command
Create sensor to show this in memory command value
Configure RRD4J to log this sensor
Can create instantaneous power and KWh sensors and log both to RRD4J as well as show the values on you panels.

Hi Richard,
Hi Richard,
You shouldn't need the heartbeat rule, you should have a sensor called Pulsen and the sensor/protocol will be responsible for updating the pulse count.

Obvious thing I missed off was to insert the fact after creating it: -
rule "initialise"
