Inovelli Blue 2-1: Inductive load in parallel - best practices?

In my bathroom, I have two switches. One for the lights above the vanity (with hue bulbs) and one to run power to the bathroom fan which is a Panasonic Whispersense DC exhaust fan.
Power comes into the box and pigtails to the fan and the lights. Separate neutrals available.
I want to install a Blue series 2-1 for the lights and either use a wirenut to just hard-wire the fan, or ultimately get a blue series fan switch. My initial test was that a blue 2-1 for the lights and in parallel (split power, separate switched loads) a regular switch for the fan did not behave well at all. The power seems unstable to the lights and the LEDs flicker/pulse regardless of the state of the switch for the fan. Did I damage the 2-1?

Am I out of luck in this scenario? Will putting a blue series fan switch solve the issue?


I’m not sure I totally understand what you tried, but it sounds as if you tried wiring a fan and lights in parallel on the same blue 2-1. Regardless of what you tried, the blue 2 -1 is not designed or rated for an inductive load so it should not be used with an exhaust fan.

Regarding the use of a Blue fan switch, apparently there are several models of the Panasonic Whisper line. There is a thread or two in here discussing the use of the Blue fan switch with those fans. Some have been successful and some have encountered issues. I would look for those threads and read through them.

Hi - thanks for the response. I’ll try to explain a bit better. The neutrals are joined and tied to the 2-1. The line is split to a normal switch and the Inovelli, each of which has a different load.

------- Line ----------| Inovelli 2-1 |----------- lights
|-------------| regular switch|---------- fan

As to the threads, yes, I saw some of them. Panasonic has so many models it is maddening.
I saw that the WhisperGreen (FV-0511VKS2) seemed to have problems, while WhisperChoice (RG-C811A) and WhisperFit ( FV-0511VF1) seem to work. I have a WhisperSense (FV-0511VQC1). There’s finally the WhisperValue (FV-0510VS1) and WhisperCeiling (FV-0511VQ1). These latter three are not confirmed to work or be problematic. SOOO FRUSTRATING!

What you wired should have worked fine. Possibly the lights are simply not compatible with the switch.

Hi PJF - they’re standard Philips hue A19 bulbs which seem fine in other locations. I wasn’t sure if having an inductive load in parallel (as shown) would cause the weird problems I’m seeing (flickering LEDs in the switch, occasionally the lights themselves flicker on/off when starting. This was a switch where the neutral came loose when I pressed it into the box, but I have repaired that (and learned two valuable lessons a) how the switch behaves with no neutral and b) to double/triple check that everything is nice and secure and the wires are tucked nicely behind the switch.
