I have like 11 switches in my apartment now and they have always worked flawlessly with Homekit. I like the little subtle lights that illuminate when the light is off, so that you can find them in the dark.It's worth understanding that these, like all smart wall switches, are actual wall switches that you will have to swap with your current switches in the wall. This involves actual electrical wiring, like you hire an electrician to do. You might think switches would be trivially easy, but there is a learning curve, and dealing with slightly-too-small wall boxes and very stiff wiring can be frustrating. It takes 2+ hours for me to do a set of 4 (2 pairs in 2 wall boxes), and that's in new construction where there are no surprises or challenges.Also note that you need a neutral wire for these. My wall boxes all have all the wires so it was fine, but as I understand it, older places may not have all the wires in all wall boxes.

I bought this to use with the HRKL10 for the 3-way circuit for the staircase. It only worked for about an hour after I set it up. I checked the network and the remote device is still connected to the network. The remote switch un-paired it's self from the master HRKL10. I performed the setup again and it took several attempts to get it to pair with the master which is about 25 feet away. Thinking it might be a faulty master (not able to pair with a remote), I switched it out for another HRKL10 that was only used for a single switch. The remote still unpaired from the master (or the master unpaired from the remote).So now I have a worthless remote switch.edit update 09/07/2020 - I recently had to replace my router. This meant I had to reconfigure all my devices. Low and behold, this remote switch now works as expected! I don't know if it was because of the new router or that I forced all 5GHz compatible devices to the 5GHz network and limiting the 2.5GHz network to only 2.5GHz devices. Whichever it was, the remote switch now works!

Super easy to install. I bought 8 in total, 2 dimmers, 5 switches and a remote. Each switch has the ability to screw down two of each wire so if you have a couple switches in a gang box you can tie the two switches together with the included pigtails and continue your daisy chain of wires to the next receptacle without wire nutting a bunch of wires together. Connecting to Apple HomeKit was fast and they respond immediately. BUT, I have had a couple stop responding. One dimmer and one switch got stuck and wouldn’t turn off. Flipping the power off and back on fixed that. The dimmer has a switch on the front for doing that but a standard on/off must be switched off on the breaker panel. I started off with two of these and after 4 weeks bought the other 6. Happy so far.

Edit: after about 1 year the switches are slowly dying and having to be replaced they just stop working all together out of 9 that I’ve installed 3 have been replaced over the past year due to the electronic relay failing......Works perfect I’ve got these in 7 rooms now and I haven’t had a single connection, setup, or automation issue with them. It hasn’t mattered if I use my phone, Siri, a automation, or the physical switch each time it’s worked flawlessly

I bought 4 switches, and 6 remote switches. All of them started emitting a high pitch whine when the small LED as on (the switch was off). We had to leave 2 sets of hall lights on overnight to be able to sleep without the noise. I also had to factory reset the entire system when we had a power outage. They refused to talk to each other or HomeKit/Alexa.I've removed them and replaced them with Lutron Caseta switches. The Legrand brand won't be coming back into our home.When they connected, HomeKit and Alexa both worked. HomeKit was more stable than Alexa, but overall we were happy until the high pitch started from 4 of the set. The noise wasn't limited to just the main switches or just remote switches. I had 2 of each style start making the noise. I checked the line voltage and it was at 123v. Not enough to elicit any issues from over current.

When it works is is great...seems like once a week it drops out. It is next to the garage breaker box so I just flip the breaker off and on and it finds the other switch in about 10 sec...works great till it doesn’t

Worked great once I figured out how Lowe’s had re-wired the kitchen and dining room lights on their “Turn-Key” kitchen remodel. The switches have to have a dedicated neutral wire which is hard to determine on old wiring. Had to have an electrician friend trace the wires out for me. They work awesome with the Apple HomeKit app.

We were never able to figure out how to install this.
