Trouble getting current power from wemo

Setup, Configuration and Use Runtime
,
1

Hi,

I recently upgraded from Openhab1 to Openhab2 and I’m having some trouble getting the power usage out of my Wemos. I have no trouble controlling them.

I have tried using the 1.9 Snapshot binding as well as the Openhab2 binding.

I have tried configuring the Wemos as things, but this didn’t work at all. I wasn’t even able to control them at that point.

Currently they are configured as follows with the 1.9 Snapshot binding. With this I can control the state but not get the currentPower. This setup is the same as I used in 1.8.3.

Switch		LivingRoomHeaters						(PersistenceGroup)	{wemo="Insight-1_0-221520K12005E8"}
Number		LivingRoomHeatersPowerUsage				(PersistenceGroup,Graphed)	{wemo="Insight-1_0-221520K12005E8;currentPower"}

Can anyone see anything wrong with that?

The only mention of the wemos in my logs are that they have been discovered.

In the events log the status changes from null to zero. I suspect this is the state being restored from persistence however as it only happens after restarting Openhab.

Any ideas?

This is what I’ve tried with the OH2 binding.

My thing

wemo:insight:Switch2 [udn="Insight-1_0-221520K1200621"]

My Item

Number          BlanketPowerUsage             (PersistenceGroup,Graphed)      {channel="wemo:insight:Switch2:currentPower"}

The OH2 log says that the UDN has been discovered but doesn’t say anything Wemo related after that. I can neither control the state of the wemo or see the power.

What have I done wrong?

I’ve just got it working by setting up the link in the Paper UI instead of the in the text files.
I was hoping to avoid using the Paper UI though. Is this possible?
