Monoprice 15902
Update June 15, 2019:
Monoprice has stopped at 5 month mark. I am going to replace the batteries and see if it comes back. Reporting intervals were adjusted in the beginning to save battery life. Grafana has battery level and all other channels until June 5 (11 days ago) In HabMin it reports node is not communicating with controller Putting batteries in it has brought it back from the dead. The sensors status immediately changed in HabMin and shows online. Motion so far does not seem to be reported. Illuminance, temperature and humidity have reported values so far
update Motion has begun to report! Batteries seem to have restored this sensor to full fuctionality
in habmin reported as ZSE40 Zooz 4 in one sensor
TLDR: works with openHAB but not first choice functionally
Protocol: zwave
Channels reported:
motion
luminance
humidity
temperature
motion alarm
battery level
Discovery in openHAB:
easy, install batteries, click discovery in openHAB, pops up as unknown, paper clip in little hole, pokey pokey, light blinks, device gets recognized
Battery type:
2 x AAA, delivered new reporting 100%
last a little less then 6 months
cheap: $30us
kind of big and clunky looking, square 2.25" x 2.25" x 1.5" (57mm x 57mm x38mm)
comes with two AAA batteries and a little piece of double sided tape
motion reports on motion channel and on motion alarm channel
More details:
This motion sensor seems to have a short detection range, you must be fairly close to trigger it. How close? Like 5’ away (1.5m) This is at odds with some of my other motion sensors that trigger thru an open door from the next room 30’ away (9m) It also seems sluggish the first time detecting motion although it does seem to get quicker after a few triggers.
The Monoprice motion sensor also seems to have a ‘cool down period’. In other words, once motion is triggered it requires a period of no motion before it will detect motion again. This is sort of like the way you would expect an outside motion triggered light to work. This behavior does not work to well with a automated lighting system where you wish the lights to stay on as long as there is activity in the room.
I have tried adjusting the Configuration Parameters (from in Habmin) and the Monoprice is much less configurable then some of my other sensors. Specifically, the Monoprice motion sensor has the following Configuration Parameters:
1: Temperature scale (Celsius or Fahrenheit)
2: Temperature offset
3: Humidity
4: Light sensor
5: Trigger interval
6: Motion Sensor Sensitivity
7: LED
Some of my other zwave sensors have many parameters including reset in milliseconds but the scale for trigger interval on the Monoprice is a number. From the factory this was set to 3. I changed it to 1 (it does not allow zero) to see if it would reset quicker. No difference has been noticed. I turned the LED off and that worked. I also set it to sensitivity to ‘highest’ which also seemed to make little difference.
In spite of all of the above, I’ve continued to attempt to use this sensor. I decided to try it in the bathroom for a couple reasons. The first reason is in the bathroom a shorter range of detection will matter less. (the bathroom is a small room) Also the matter of the long reset matters less because usually you don’t spend hours in the bathroom. The Monoprice also has a humidity sensor and I have visions of the sensor being able to detect a rise in humidity and therefore trigger openHAB to signal I am in the shower and adjust the automation accordingly.
I’m happy to report the sensor does seem to report humidity but after getting influx and grafana working in order to see if the output is something usable for detecting a shower running, I’m not sure it will work quick enough to be of use.
The Monoprice is apparently the same exact product as the Zooz. I actually tried to buy the Zooz on amazon and it was unavailable. When I tried to order the Zooz motion sensor on amazon a little pop up box said amazon was not currently selling the product because to many members had reported problems. I ordered the Monoprice instead.
Over all I’m not thrilled with the Monoprice but I haven’t thrown it out or tried to return it yet either
habmin rocks for zwave!
