I think the Girder bridge is forcing double-quotes around the Event String so that you cannot directly send a payload.
The parameters to ieventc are ieventc <address> <port> <password> <eventstring> <payload> [status/stresstest] [event-repeat] [sleep] [login-repeat]
If I set the property GirderDevice.Event String to eventstring payload then HB apparently sends ieventc "eventstring payload" so that Girder interprets "eventstring payload" as the event string.
In order to send a payload I have to set the property GirderDevice.Event String to eventstring" "payload so that HB will send "eventstring" "payload".
You're right, it does enclose the eventstring in quotes. It does this so event strings can contain spaces. I'm afraid that if I change it at this point, it will break existing configurations.
Maybe it needs an additional Property for Payload that will be sent after the event string
That would work. I don't know how useful it would be but you may want to include the other parameters too: [status/stresstest] [event-repeat] [sleep] [login-repeat]
That would allow, for example, sending an event 20 times at once. Can't think of a practical application for this though.
