Scene not controlling light

[boser]

I've created a scene with a

2476DH SwitchLinc Dimmer v.00

2486D KeypadLinc Dimmer v.2D

 

From the ISY console I can

Turn the scene on (both devices turn on)

Turn the light on and off (by controlling the light, not the scene)

 

If I turn off the scene, the light does usually not turn off (sometimes it does turn off), although the ISY reports it as off.

 

I do not get communication errors, and the light seems to be working fine (just not when being turned off as part of the scene).

 

I've added a program that queries the state of the SwitchLinc whenever it is turned off. Now when turning off the scene the ISY console briefly shows the light as off, but then it right away turns back on! Unfortunately turning it off programmatically does not actually turn it off, even when I turn of the light (rather than the scene) - which is working from the ISY console. Go figure.

 

Anybody observed this behavior? How can I debug it?

I see two things that immeditly concern me. First, then version of one of you switches is v0.0. This suggests to me that your ISY did not recognize the device. What ISY firmware version are you running?

 

The second is that you appear to be getting response "sometimes". My first reaction to inconsistent response is to suspect comm problems. Do you have two access points confirmed on opposite LGS of your electrical system? Do you have your PLM plugged into an outlet or circuit that includes lots of computer stuff?

Thanks! Your feedback prompted me to uninstall and reinstall the dimmer switch, it came back as version 35 and works reliably!

 

I do have a phase coupler installed and my software version is 3.3.10 on an ISY 99i PRO.
