A few questions about the Dimmer Switch

[Eric_Inovelli]

Hey @jtronicus – sorry for the delay here, I was waiting on a couple of these answers!

Thanks for writing in and asking the questions, we’re happy to help.

@jtronicus

Does the Dimmer Switch use leading edge or trailing edge dimming?

The switch uses leading edge dimming

@jtronicus

When using the Dimmer Switch with a neutral, is there a minimum load requirement?

I checked with the manufacturer on this one and they said there is no minimum load requirement. However, what I will say is that there are certain bulbs that work and do not work well with the switch and so I started a compatibility thread that will outline the ones we recommend as well as community recommended and verified bulbs.

@jtronicus

If the light is currently on at 20%, and I push the power on button 1x (assuming parameter 9 - default level is set to 100%), will the light change to full brightness? or will I need to hold the button down until the brightness reaches 100%?

Yes, this is correct. If Parameter 9 is set to 100% then when you tap up 1x on the light switch, it will go to 100% (no need to hold). Whereas, if Parameter 9 was set to its default of 0 (Previous), and your light was on at 20%, you’d have to hold the top button to get it to 100%.

I understand that an official aux/add-on switch will not be available for some time, but the switch does support some 3rd party (GE and HomeSeer were mentioned on Reddit). I have a Leviton add-on switch laying around from a previous upgrade (VP00R-1L). Does anyone know if this add-on switch will work with the Inovelli dimmer?

Great question – we haven’t confirmed this specific model.

@jtronicus

If I were to disable the relay on the On/Off switch, can I associate it directly with the Dimmer switch so that it acts like a 3-way switch (probably without the dimming functionality though)? If so, would the on/off switch directly command the dimmer switch, or does the command need to be routed through the controller first? I am looking for an extra layer of redundancy. If my controller goes offline for some reason I prefer to have the 3-way functionality still work.

Great question – @EricM_Inovelli – any idea on this one?

You could do this with two On/Off switches for sure, but I’ve never thought about mixing the two – now you have me curious!

BTW, I think I found a typo in the instruction manual pdf (https://inovelli.com/wp-content/uploads/2019/06/LZW31-SN-Manual.pdf ):
On Figure 1.2 on page 9, the description field for parameter 9 and 10 says that it disables the internal relay. I think it is supposed to refer to the default dim level, and not anything about a relay (likely a copy/paste error)

Great catch! You’re right – thank you! Surprisingly, I was able to send this in for them to print for the upcoming batch!
