There are some who swear by these (and the AEOTEC dual nano).
They look like ordinary decora switches on the outside, but inside the box you can easily put an enerwave RMS2-PLUS or the equivalent AEOTEC dual nano, or the Quibino(?).
The client (or spouse) doesn't even know that the switch is controlled.
Sometimes, people have expensive switches that they want controlled, but they don't want to replace the extraordinary switches that they have.
The downside is that the position of the switch doesn't necessarily reflect the state of the light. That is, they could be down, with the light on.
(Momentary switch versus toggle switch in the AEOTEC).
Also, these from enerwave are VERY cost effective.
The house we moved into had a few sconces on the walls. They were hardwired and had small switches right on the fixtures.
My wife wanted to change them, but the replacements didn't have switches. I could have wired up a switch on the wall below the sconce, but it would have been unsightly and she wanted to put something there anyhow. I put a similar device (an Aeotec Nano dimmer) in the electrical box behind the sconce - problem solved with high WAF.
You may already know this, but for those that don't... you never want to put something like this inside a wall. Any mains-powered device MUST be enclosed in a proper electrical box and it must be accessible.
I have a similar (not these, but dual relay) that I mounted in a box to control a bathroom fan (and light) above some aquarium stuff I have in the basement to act as venting for humidity. Can still be controlled by the switches but a simple 4-1 sensor made it so the fan could be on when humidity got too high and the light turned on when there was motion OR the contact sensor for the basement door was open.
My plan for these are to control some Christmas inflatables I have. Kindof a waste really because they are dual relay and I have not come up with a good reason why I would want the inflatable fan running but not the lights... But I will probably wire it up that way just because.
I also have a bunch of ZigBee on/off switches meant for (and in use) in inflatables... but I am trying to get away from ZigBee a bit now. Except there are more (and cheaper) options for it so far so that is pretty much impossible.
I have an aeotec MultiSensor in my sump room monitoring humidity and turning on my exhaust fan thatās controlled by a Lutron Caseta switch. I know they should t be hidden in the wall permanently, was just trying to see what others were using them for. Thanks!
I used mine to control a bathroom vent fan. I'm switching from ST where I had the OneTap app (it was very handy) which allowed me to program it to turn itself back on if it was physically turned off from the switch, only if the bathroom light was on. A couple of my kids like to drop a deuce and leave the bathroom fan off. I started with having it come on automatically with the light but the little punks kept turning it off.
It warmed the heart to hear them turn it off and one second later it kicked back on lol. Then again...then they finally got it. I had it installed for about a year with no hiccups, which is why I want it to work with Hubitat. Right now it's an "unknown device."
bcopeland looks like āthe guyā....love it!
Anything official on ENERWAVE IN WALL RELAY? I have 2 to install. Converting over from ST and upgrading along the way. Thanks for any help
Bumping this as I have picked up an RSM2-Plus to separate the function of two light fixtures on the same switch. In order to keep the lag time from the control (a Zooz ZEN23 in smart bulb mode) to the relay to a minimum, I want to do direct association. While the On and Off functions do work correctly (once I set up the multichannel association via the ZWave tweaker driver), the status does not automatically update with the Eric Maycock drivers, and I don't want to have to do polling. Status DOES update automatically with a Qubino dual relay and direct association, but the lag on the status is almost 2 seconds. Any hope for this driver in 2.2.8, @bcopeland ?
New Hubitat owner here.. Converted my parents house over from Smartthings last week, and I'm in the process of converting mine over to a two hubitat hub system this week.. I also have one of these RSM2 (original) switches and I will probably replace it with a PLUS version.
I got the current one working with the Eric Maycock drivers, but like mentioned above.. It doesn't sync the status and then when I go to control it from Google Home, it doesn't shut off because it thinks it already is off.
Looking forward to any developments on this front.
Oh and I'm in love with Hubitat and I'm so happy to finally be ditching that no direction mess that became Smartthings.
I have had 2 Enerwave RMS2-Plus relays in my "other " drawer for months, and I had almost forgot about them!
Much appreciated.... Thank you....
(now, I just have to wait for 2.2.9 !!!!)
P.S. I know that you've been busy with all the z-wave stuff and the series 7 chip.
I got the driver loaded and working and it created 2 child devices. Played around with other drivers and messed it all up. Excluded and re-included and now I donāt have the child devices.
Edit: found my answer here:
Post #9 by gmf
Initially the child devices didnāt load. Per some other post in the thread, I had to change and save ādebug Logging Levelā to āallā and the child devices appeared. I then changed and saved ādebug Logging Levelā back to ānoneā and all is well!
FYI. (Previously posted somewhere else, but it also goes here):
FYI.
I was recently contracted by a client who wanted smart control of his switches, but wanted his existing switches to remain. The solution, is to use "in wall relays".
However, given, that the house is relatively older, the internal junction boxes ("gangs"), are relatively small. Here I present the actual sizes of the three smallest dual channel devices that I could find.
(Note: There are significant differences between these, but if size is your key parameter, this should help you decide.)
Type
Protocol
Size
Aeotec Dual Nano Switch
Zwave +
4.318 x 4.064 x 2.032
Shelly 2.5 UL
WiFi
4.2 x 3.6 x 1.4
EnerWave
Zwave +
5.156 x 4.369 x 1.575
Quibino Flush 2
Zwave +
2.99 x 2.01 x 0.96
Fibaro FGS 223
Zwave +
4.24 x 3.81 x 2.032
If anyone is aware of another dual channel device that is comparable, please let me know, and I amend this chart.
Please note: For our European friends, (from what I understand), size is not an issue, as there is plenty of room inside the junction box. Also, the newer, North American plastic boxes are also much larger.
I would like to add to this thread that the official driver is "Generic Z-Wave Plus MultiSwitch". I read this and the other thread and it wasn't so easy to tell.
This component has been working amazing for the last 2 years pushing a small blower fan motor.
