Is this possible? (GE Z-wave Switch + Hue)


#1

I have GE z-wave switches throughout my house for all of my light switches. Recently I replaced some of my dumb bulbs on these switches with Hue bulbs.For the room with the Hue bulbs, the switches are in an always on state and I’ll use whatever controls (voice, app, etc) to control the bulbs. However, this creates a potential scenario where a guest, housekeeper, etc will try to turn on the z-wave switch and nothing happens. often they’ll intuitively turn turn the switch off then on again to take manual control of the bulb which is less than ideal.

As a potential way of dealing with this scenario,I’m wondering if it would it be possible for a smart app to detect a redundant “on” event on the z-wave switch, and use it to trigger the hue bulb to on.

Basically something like this (pseudo code)

.on(switch_state_change)
if(switch.state.on) { // turn on hue bulb and set brightness to 100% }
else if (switch.state.off) { switch.state.on === true }

I havn’t seen any apps that do anything like this, so I’m wondering if that may be for a reason. The only reason I can think this wouldn’t be possible, would be if the switch doesn’t actually send an event to ST when the switch is turned on if was already in an “on” state.

Any insight on this would be greatly appreciated, Thanks!

You should not use a smart switch that controls the current with a smart bulb. Let the Smart bulb decide for itself how much current it needs and keep it always supplied with available current. The reason is that if you are regularly turning the current on and off with the switches, the inrush when the switch is turned on can damage the bulb. It’s all right if there is the occasional rare power outage, but otherwise, don’t have these bulbs on a switch that controls the current to them, smart or not.

Also, you are correct that most switch models will not send an on event to the hub if the switch is already in the on state.

So what do you do instead? Well, there are many options. :sunglasses: See the FAQ for what switches to use with a hue bulb for details. You will be able to have a switch on the wall and using that switch will turn the bulbs on and off, but you will never have the problem where the switch is off and so the bulb doesn’t come on. Again, details in the FAQ:
