Qubino Z-Wave Plus 110-230V or 24-30 VDC On Off Thermostat Module ZMNHID3 with External Temperature Sensor

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).UPDATE Mar 9, 2019: I put the first one as an alarm on my freezer which only works part of the time. It transmits the temperature reliably so it is not completely useless. I bought a second to use as a temperature controller for my meat locker (before I discovered the unreliability from not remembering its previous state). I cannot rely on the device to operate reliably. It does not remember the switch state on I1 (thermostat on-off) even when programmed into the parameter as a NO mono-stable switch. If the power cycles it tend to shut down the thermostat function and one must go through a convoluted process to reset the switch to proper function. A switch on I2 sets the thermostat to a parameter set temperature, but doesn't update the setpoint. This appears to be designed for cooling as an afterthought. It has an override function that reactivates in heating mode only at a set low temperature (anti-freeze setting). And again it does not report its status to Domoticz in Heat or Cool mode. So Domoticz can't know if it is on or off to check and the command to activate the thermostat does not work in Domoticz (v4.970).I currently use the second as a freeze alarm on my air conditioner in case the blower stops working (to keep the evaporator from freezing and sending liquid back to the compressor). It is even able to reliably transmit through the steel AH box. It does handle 240VAC, but I could not get it to work reliably on 24VDC with a 1A switching power supply and almost no load (buzzer). I wanted to power it from the 24VAC transformer using a bridge rectifier and power a buzzer for an alarm, but that did not work. Looking for a 240VAC SPDT relay to use as a 24VAC disconnect if the evaporator freezes.UPDATE May 2019: I found a bug in the micro-controller firmware. Sending the setpoint temperature between 38-42F doesn't work. There is an error in the C to F calculation and it reports back 28F after updating the setpoint value at the Z-Wave controller. I tried this on both my On Off Thermostat Module ZMNHID3's and got the same results. I know there are other bugs in the firmware that I can't find. There are mistakes in the XML coding for the OZW protocol. I would really like these to be fixed. I have not been able to contact Qubino about it. It works mostly, but having a temperature range that cannot be used it limiting. It may even be a rational decision since "who set their thermostat at near freezing?" Additionally, there has been a tendency to report incorrect temperatures lower than actual. I have had several false alarms reporting below 0F temps when actual temp was in 50F's. It will then correct with the next reporting cycle or polling cycle. Not impressed with these malfunctions.

Do not count on these. I put one on my fridge and it doesn’t stay connected to smartthings. And since it’s not officially supported by smartthings nor does qubino offer officia support for smartthings integrations through the “custom handlers” they themselves recommend, you’re very much on your own. Mine quit responding within a month of installation and will not re enroll even after completely wiping them out of smartthings. Luckily they failed in such a way that they are keeping my beer at around 36.5 degrees, but I’m thinking of replacing them entirely.

After spending a considerable amount of time trying to make this device function as advertised and several emails with technical support i was advised " As far as we know there’s no way to edit the inclusion of Vera gateway. We are aware that the thermostat is not working properly with Vera, but that is not a fault from our side. All the devices to be properly included in the gateway needs a proper inclusion to be written from the gateway producer side. For our Thermostat On/Off unfortunately that’s wasn’t done at least for the version H1S5P2. So I don’t know if there any possible solution from our side for your issue." They will not swap the ZMNHID3 for the relay module that they said would work. Its past my 30 day return window so I am stuck with two of these really expensive temperature probes.While the manufacturer didnt want to swap out the device, the seller was willing to and I highly reconmemd the seller!

This is the first z-wave device that I have found that was advertised to measure and report a remote temperature from below zero F to over 100F. Most similar devices will operate a thermostat or close a relay, but not provide a reading back to the controller. Many people use a weather service to provide a local temperature report to their ISY994. I have mounted this module inside the house using a 24v power supply, with the probe going through the wall. "Officially" the ISY994zw does not support this device with the production software, but I found that the new V5.0.x does support it. I updated my module to a beta 5.0.14, which has now progressed to a release candidate 5.0.16. The reason for the 4 stars is that I did need to write a very simple program in the ISY to periodically query the temperature sensor to obtain an updated reading. The temperature reading updates were not automatically available to the controller for display, even though the thermostat portion would respond to the sensor. I currently query this unit every 10 minutes, which provides the information that I need to adjust HVAC settings in the house. It has been working flawlessly for the past year or so.

For the price I would expect this to work out of the box. Upon adding this to my Z-Wave network (Samsung Smart things) it was added as a home power meter. I excluded and included it into the network several times to no avail. So if you're looking for something to work as a Z-Wave thermostat with probe keep looking.

It seems like an OK device. I added to homeseer easy enough but i can only get it to see 4 out of 5 child devices. The bigger issue i have is that the temperature probe cable connector doesn't really "click" in. Just laying on my desk the connector falls out.

works great, changed the way we heat to boiler and saves us a lot of money.I’m the using thermostat with smarthings. had to work a bit to code the right handler for my needs (fun) but it pays off and now we have full control of hot water

...once you're able to get them setup. These devices do what they are supposed to but the setup in SmartThings is horrendous.

I'm controlling my Hayward swiming pool heater with it. It was a real challenge to make it works with my Samsung Smartthings hub. I use the temperature probe to return the water temperature. It works great!!! Don't buy this product if your technical skills are not advanced.

Ok
