I have purchased a Gen 2 dimmer, and to be honest I’m liking it so far – although I agree with other posts that the software is in dire need of some polish. For my simple use case of setting up the dimmer and then using HomeKit for the rest, it worked fine.
I’m wondering about how multiple dimmer switches can be installed to control a single light. With Generation 1 there were separate slave dimmers, which would connect to the ‘S’ terminal. With generation 2, there is still an ‘S’ terminal, but no slave dimmers?
The website states that Generation 2 products support “20-way wireless communication with other Lightwave dimmers” – implying that dimmers should be able to speak to each other for multi-way configurations? If that’s the case, how do I go about setting this up? How are the secondary dimmers to be linked to the primary dimmer? How are the secondary dimmers to be powered?
I tried speaking to LightwaveRF on the phone, and unfortunately the advice I got was a bit confusing. The guy suggested setting up HomeKit automations to replicate the state of one switch onto the other. I don’t believe this approach would support dimming, nor do I see how the secondary switch would be powered if it’s not wired up in-line with a load.
I do not know what the plans are….
but my guess is either we are waiting on new products such as a gen2 slave-switch or a gen2 wire-free-switch
We’ve just purchase the gem 2 dimmers and have set some up as two way as Lightwave suggested.
We have two normal dimmers and using Apple HomeKit there is an automation that mirrors what the opposite switch is doing.
It works and dims but I think it’s an expensive way of doing it and it’s clearly not the original intention
Do lightwave have instructions somewhere for doing 2-way switching with Gen2?
After a twitter exchange I was informed that 2-way switching isn’t actually available yet (surprise surprise), but that it was coming in “the next few weeks”. That we at the start of October.
I raised this with LWRF, especially since the product information from the start has suggested 2-way switching. They told me (back in November) that they hoped to introduce the functionality at the end of November, but it’s not there yet, and the current information published by them is that it will be available in December (which is almost over!).
I am not clear how it will work. The recently published information is that it will be functionality that you activate via the app, whilst the person who called me after I raised the support call told me that the switches themselves will get a firmware update after which they will figure out for themselves when they are connected in a two-way configuration, and ‘just work’.
It’s frustrating, because I have three LWRF G2 switches that I can’t use because I only bought them for the two-way functionality.
I am interested how it’s setup on Homekit. The LWRF guy told me it could be done, but I installed them, set them up in Homekit and tried to get it working but couldn’t see how, so removed the switches again – maybe I missed something (I am not that familiar with Homekit). I ‘grouped’ them, but they didn’t work correctly as a 2-way system.
When this finally works (soon, I hope), it will be great – this 2-way functionality is potentially a massive benefit over the G1 dimmers.
BTW, here’s the LWRF webpage I was referring to, which suggests that 2-way switching will be available in the app from sometime in December.
The wiring is pretty simple if using in an existing traditionally-wired 2-way circuit, you just won’t use the common. The guy told me that the middle ‘S’ terminal is a dummy terminal on the G2 dimmers, and doesn’t do anything… which kinda begs the question as to why it’s there!!
2-way was live as of yesterday when i got home! you need app version 1.3.1 and then create a dimming group under automations with both dimmers in it..
So, how do the switches communicate – by WiFi, RF or black magic? I.e if the WiFi/ RF is ‘down’, will the 2-way switching still work?
I’m an old-fashioned kind of guy, and I trust hard-wired connections. 2-way switching via ‘app automation’ concerns me (in terms of reliability)
I’ve been waiting for a reply on this (along with other questions) from LWRF for a couple of months now… any advice would be greatly appreciated!
