Consider whether it is a situation of overload. How many light bulbs are installed on the light fixture? Are they LED lights? What's the rated power?

Try to install the switch to another location, to control another light, test whether the same thing happens.

The type and wattage of the bulbs are within the switch's supported range, so even with 10 installed simultaneously, it shouldn't be a problem. It may simply be a compatibility issue, you can try to install just one bulb, test what happens.

Given the vast number of fixtures available on the market, we can't verify the compatibility of the switch with each one. I suggest you buy the products and test them, keeping only those that work without any problems.

By the way, why are you trying to control the smart light bulbs with a smart switch? Typically, smart switches are intended for use with non-smart fixtures. When smart bulbs are controlled by a smart switch, bulb's smart ability will be disabled once the switch is turned off -- meaning cutting off light bulb's power supply.

Thank you for the reply. 

 

WRT your switch question, maybe I'm thinking about this the wrong way, but here is the reasoning: 

 

I mainly use Alexa to control my lights (wake-up command when I arrive, sleep command when I leave). There are instances when friends come over who don't know my commands or that I use Alexa at all. And they struggle to get the lights on, and when they leave, they switch them off, leaving me with the need to switch the switch on again before being able to use voice control. 

 

I would like to use a smart switch that basically executes the simple task of "Alexa, lights on/off", so that I can always use voice and/or the switch. A simple Hue click button would probably be enough, but I wanted it to look neat. 

 

Am I thinking about this the wrong way?

I believe a suitable solution is to replace all the visible switches with smart switches, while using regular bulbs. Your smart bulbs can then be installed in areas where the switches are less obvious or inaccessible to guests.
