Hi,

 

I am using a #2420M motion sensor to the ISY. It is a Rev 1.1 unit.

 

I goto new insteon device, put the address, name, then scroll down to the end for the motion sensor. I hit add & I get this message:

 

The following devices could not be added:

 

xx.xx.xx (2420M-SP) Insteon Motion sensor v.00

- Cannot determine Insteon Engine

 

 

Any ideas what to try?

 

Thanks,

Rich

My first inclination would be to make sure I had the latest version of ISY software

I am using ISY: 3.3.5

Next thing would be to move the Motion Sensor closer to the PLM (assuming 2413 Dual Band) so that RF range is not in question. Also that the Red LED is blinking confirming the Motion Sensor has been put into linking mode prior to clicking Ok on New INSTEON Device.

 

That error message indicate the motion sensor did not respond to the engine query command which is the first command attempted (RF range or not in linking mode).

I moved it right next to the PLM & it says unrecognized device.

 

I am going to try another battery. I have 4 other same generation motions. I also might RMA it too if that does not work.

Moving the Motion Sensor to the PLM location has solved the comm problem where the motion sensor did not respond to the query insteon engine.

 

Now the ISY does not like the cat/subcat the device is reporting. Run Tools | Diagnostics | Event Viewer at LEVEL 3. Run another New INSTEON Device and post the event trace so we can see what cat/subcat the old v1 motion sensors are reporting.
