A failure to communicate

Recommended Posts

 I have had a 2476D v.37 controlling room lighting.  No issues for the past 3-4 years.  - Call this Dimmer #1

 

Today, I added a 2477D v.44 dimmer to provide a secondary position in the room to control lighting. -- Call this Dimmer #2

 

When I remotely (via iPhone/MobLinc Pro) turn on Dimmer #1, the LED bar moves upward on both dimmers and the light will turn on/off.

 

When I remotely (via iPhone/MobLinc Pro) turn on Dimmer #2, the LED bar move upward on both dimmers and the lilght will turn on.  When I attempt to turn off via Dimmer #2, the LED on both dimmers will slide downward but the light remains on. 

 

When I operate either dimmer directly via the paddle switch, the operate without fail. 

 

I placed an extra access point near dimmer #2 to determine if I could improve communications.  I see the LED on the access point flash for all of the combinations noted above, however, dimmer #2 will still fail to turn off the light.  Again, the LED on the dimmer switch will respond properly to on/off commands, but the light will not turn off. 

 

Any suggestions?

When you control a device, only that device responds, not any of its links. If it were otherwise, then you could end up in an infinite loop. The correct only way to control two (or more) linked devices is to control the scene that includes those devices.

I have the 2 dimmers set up in a scene.  I get the same results when I used the scene button on MobiLinc Pro to turn on/off the scene.  The LED on both dimmers will move up/down each time I activate the scene button.  The access point will "flash" for each signal.  The room light will not always respond on/off.  The response is erratic.

If the LED indicators on a switch move, but the light does not come on, I would tend to consider three possibilities:

 

- loose wiring connection somewhere

- failed bulb

- failed switch

 

I would be checking voltages at red wire on switch to see if present. If not, switch is possibly failed. (Sometimes a factory reset can "fix" a failed switch.) If the voltage is present, I would consider the other two possibilities.

Are you tapping the Off paddle in Mobilinc or Touching and holding for a moment?  It's possible you are issuing a Fade down rather than an Off.  Instead of using the graphic paddle for a device, try clicking the Config gear for THE SCENE (not an individual device) and select Off.  Does that work as expected?

I am taping the Mobilinc paddle. I have also tried the scene icon and still do not obtain consistent actions.

 

One of the dimmers is powering the lights. This dimmer has been installed for 7 yrs. I added a second dimmer last week to enable light control from across the room. It is the new dimmer that is problematic.
