Motion Sensor 1 causes other LED light to flicker

[tpventure]

I have a Insteon Motion sensor 1 device that correctly detects motion and sends a signal which my program will then send on ON command ot a ON/OFF receptacle (which has a LED strip light plugged into it).

Every time that the sensor is triggered the led ceiling light (about 3m away) will flicker and then stops.

Now this sounds like the RF being sent out by the motion sensor is affecting the ceiling LED light - but is there a work around?

For example should I insert a wait period after the command to turn on or off the ON/OFF device?

In doing some searching it appears the RF is 915 Mhz?

Can you tell if the flicker is being caused by the motion sensor sending out it's rf signal (which would be unusual) or if it's from the powerline and rf signal being sent from your controller to the on/off module? One way to tell would be to temporarily disable the program turning on the receptacle, and see if the flicker still occurs when the motion detector is tripped.

If it seems to be caused by the command being sent to the receptacle, do Insteon commands sent to other devices also cause the flicker?

If I remove the on/off module from the receptacle then there is no interference with the ceiling light).

If I attach the on/off module to the receptacle and manually keep the unit in the OFF state then whenever the motion sensor gets triggered I do get the ceiling light interference (no programs running).

I do not have other Insteon devices at this time, so cannot check their interference.

I therefore conclude that the on/off module is communicating with the eisy - but why if I do not command it to do so?

Does the on/off module behave as a repeater of the sensor rf?

Yes, all insteon dual-band devices, including plugin-in modules repeat insteon traffic. It's repeated on the powerline too, and the LED light may be reacting to that. Insteon sells a 2 capacitor pack to try and avoid this problem

That capacitor in the link is out of stock except for pack of 5 blue.

Anyway that does not seem to help solve the issue.

The real solution is for me to abandon the expensive $300 led fixture and/or dimmer switch in favour of something younger than 5 years old!

So after all the testing over two days I have given up on the eisy plus on/off module plus motion sensor I and the plm with usb interface.

Smart Home devices should not be hard to set up.

For example after this testing I moved the PLM to another spot (was in a surge protector) and now the comms to the on/off module fail.
