Anyone using rm pro + TC2 switches + Google home? How can I get Google home to toggle on off tc2 light switch?
You can’t.
Voice > GHM > IHC > RM Pro > eTouch
The problem here is the integration between IHC and GHM- both TC2 and eTouch are RF switches, but the tiny and crucial difference is TC2 is manufactured by Broadlink and hence, when added into IHC it gets recognised and appears automatically as a Wall Light Switch RF, which is the problem here- GHM ONLY RECOGNISES LAMPS (and scenes).
Since eTouch is not produced by Broadlink, what happens when I add it into IHC is it won’t be recognised as a Wall Light Switch RF. I will pair it first with a physical RF remote (80 key, enough for a few hundred frequencies) and set each individual frequency for on and off. Then I will go to the IHC and create the usual User Define Remote (which we have to do for all RF remotes), let RM Pro learn the on/off frequencies and then create a scene using IHC for on/off. It may sound like a lot of work, but by the third switch, I could do it all in slightly under two minutes for each individual gang on each switch.
So by choosing eTouch over TC2, I had to pay more (about $10 each) and a bit more time setting it up, but right now I can control all the switches in my home using voice commands to my GHM. By the way the RF is quite strong, I only need one RM Pro to control all the wall switches in my 5 room BTO.
Anyway, for those price sensitive guys, there is a new alternative- Funry RF switches. About $5 cheaper than TC2 ($15 cheaper than eTouch!), most importantly, can use voice to control via GHM/AED. I was told specs slightly lower than eTouch but okay for those lower wattage stuff like lights and fans. Just to be clear, I have not used Funry before, I just saw it on Carousell and spoke to the seller and that’s what she told me. When my eTouch expires, I’ll consider Funry.
