Qubino Flush Dimmer 0-10V

First, these things are really small. They are the size of a camera battery. I purchased them for use on a HomeSeer 3 system. I needed two relays to control the open/close push buttons on my electric water valve. I obtained two of the single relay models because I heard there were problems getting both relays on a dual relay module included in certain Z-Wave systems. Plus, the dual relay module did not provide isolated contacts from the AC line. I purchased these because they have isolated dry contacts. That means none of the relay contacts are internally connected to the AC line. I also wanted to use the configuration parameter to make the relay automatically turn off after 1 or 2 seconds so it could act like an electric push button. Sure enough, they were easy to include and I was able to get a monetary 2 second relay on condition for every ON command. I noted that the 2 second duration seemed to vary between 1 to 2 seconds based on my non-scientific observation. That was not critical when you are turning a water valve on and off. They are a little more expensive than others but the others did not have the flexibility in programming. The tiny instructions provided are useless to my old eyes. There is a nice color PDF file you can download and print from the Qubino web site.

Waited months for this to be available in the US with the US Z-Wave frequency. 0-10V dimming is how my LED lights are dimmed in my shop and wanted something Z-Wave enabled. Haven't seen anything else in the market to compete.Will report back after I get some time on it. So far, so good! Gives me Dimmer, on-off, and 'meter' on in Openhab2

Unlike other multi-relay devices, this one works right out of the box. It actually shows up as a zwn-rsm2 enerwave device, which I also have, but this one works.I've experienced relay failures on the enerwave devices, so hoping I won't see that on this product.

I must first say that Z-Wave is still in early development and not for the faint of heart (technologically speaking). I am an Engineer (not electrical or computer) with minimal programming experience (started on Apple IIE DOS). I found this device could be made to work on my Z-Wave system OK. I am using Domoticz (after Homeseer said I was too stupid and would not support their products) which is opensource freeware using open z-wave libraries. The development for supporting this device is limited and there are mistakes in the open z-wave documentation. It is largely up to the hardware manufacturer to provide the development (making it work) for the open z-wave.I was able to get it to work with Domoticz in a limited fashion. I knew this going in from both very helpful The Smartest House and less helpful Qubino online documentation. The documentation is clearly written in another language and then translated to English. Although better than most Chinese generated translations is still leaves some gaping holes that could use clarification. The instruction have a lot of useless technical info for the consumer and important missing info (eg. how to tell if it is actually in cooling or heating mode). Explanations of functions and setting is technically above the average consumer.It is very difficult to change from Heating Function to Cooling Function. It requires a jumper and re-inclusion on Domoticz as the Parameter (59) is not available. Other control software will vary. The embedded temperature range -15C to 100C will allow it to be used as a temperature controller for a fridge, heater, AC, but (maybe) not for a freezer. Since I bought it to monitor my fridge and freezer temperatures while away it works, but the relay function is wasted. It took awhile to configure it as a high temperature alarm. Still can't get it to tell me when the relay is active (Q), or when I1 is pressed. Other automation software is reportedly better, but I'm not going back to HomeSeer (others require internet connection to work).

So far this thing works great for me with SmartThings. I had to add a device handler through Smartthings IDE which was kind of a pain figuring out, but there are some good walk through instructions online. Just Google this relay and SmartThings and read articles.I put this directly at my ceiling fan and now my young son can turn on/off the fan and lights separately using Amazon Echo dot. Before he was stuck with whatever settings someone else had set with pull strings.With this setup (at the fan instead of switch) the switch has to stay in the on position. But now I have three switches in SmartThings to control the ceiling fan. 1- unit as a whole (everything on or off.) 2- fan on/off. 3- Lights on/off.I suggest after purchasing go ahead and add device handler while unit is shipping so when you get it you can install it right away without having to wait.You want to do this before adding this to SmartThings otherwise you’ll be removing/unpairing it adding device handler then parring it again. With the setup at the fan unpairing isn’t easy to do.Gave 4 stars because of the extra setup you have to do but after it’s done it has worked great. It also tells how much energy is being used per relay and as a whole.
