I have two Monoprice garage door tilt sensors (ZG8101US) which are integrated into a Smartthings V2 hub along with other devices. I have been using these (identical) sensors with external - open/close sensors enabled (instead of tilt detection). One of the sensors (let’s call it sensor #2) was not recognized by the hub and I had to delete and add it again to the hub (via Z-Wave). Sensor #2 is now being recognized as a “Vision Door/Window Sensor” and it is lacking “EnableExternalSensor” function in settings, which is still visible in the sensor #1. I tried removing adding sensor #2 couple of times, but still the same. Sensor #1 does not seem to have any name/brand within Smartthings Information, as opposed to sensor 2 which is being shown as - Vision Door/Window Sensor. Sensor #1 does not have an option to list/change a driver, sensor #2 does have a driver option, and it lists as a Name - “Z-Wave Sensor”, a developer - “SmartThings” and a version number. The way I am adding sensor #2 is by a generic Z-Wave Device.
Anyways, my question is, why do these two devices are having different options and are behaving differently even though they are identical and how do I change sensor #2 so that it has similar functions (in this case to enable external (open/close) sensor)?
I do not want to delete and add sensor #1 as I am sure it will also be recognized as a “Vision Door/Window Sensor” and it will lose the external sensor functionality.
it sounds like both identical sensors were originally using a DTH. though now that you deleted and re-added sensor #2 it is incorrectly pairing with an internal edge driver. the sensor info is associated with the wrong edge driver and needs to be re-associated with the correct internal edge driver. this would be something that youd need to notify the help desk.
i have this same monoprice garage tilt sensor and its still tied to a DTH.
I personally would just replace the sensors with something newer and supported. If you’re using the external contacts anyway, just use a door/window contact sensor that has external inputs. There are several options, the forum has discussed it before.
This is an older device (pre Zwave plus) that is no longer sold. It is based on the 300 series chipset.
To report the external inputs it uses a non standard notification event type (0xFE), so this would require a custom driver.
I would be willing to write a driver but I don’t have one of these to test with, they don’t seem easy to get, and it would be spending time to support a device that isn’t very popular and easily replaced.
I would recommend another option to your external sensors. Use a door/window sensor with external inputs, or if you have power nearby a ZEN16 or ZEN17 would work great to read external inputs as well.
Thank you all for your input.
I did contact Smartthings support about this, will update the thread if they are helpful. Otherwise I will just get new sensors with external input support.
