I have been using the Samsung Contact Sensor and have not have any problems with it. I would buy it again.
As an added bonus, it provides the temperature, so you can have an idea of the garageās temperature. (It does report colder temperatures during cold Canadian winter days though...)
As for dashboard templates, I donāt think new ones can be added... but it is possible to use the āAttributeā template to setup anything that is not in the list.
There is a correct mounting for that sensor. It has an arrow stamped on the sensor that has to point up. It also says in the manual it should flash the LED when tipped (and I assume) also when the door is opened and closed.
Sometimes it is better to mount the sensor higher on the door so it reacts better.
And metal shouldn't really affect it. It is made to go on a garage door so that would be really silly if you couldn't mount it on a metal door.
And far as I know there are no user dash templates. You can request to have a different one, but adding a new one that (essentially) copies the function of an existing one is probably not very high on the Hubitat team's priority list.
I can confirm that it works on a metal door as this is what I have. Iām not sure if I have it mounted in the right direction or not, but never had any issues... (Apologies for the picture being sideways... For some reason, photos imported from the iPhone here do that sometimes...)
I now use the Package Manager app to ensure I have the right version of this app (and a bunch of others...). It also will install updates if any are available and if I want it to. Really nice!
Definitely mounted right way up more testing found that Z wave signal not working at all. Checked the Aeotec Z Wave extender may have been an issue, The outlet in the garage plugged into trips occasionally when the family run the washer and wife has her car charging. Solution move the ZW extender to another nearby outlet that is not affected by this overload condition. Tilt sensor is working now. But there is some strange stuff going on with the Dashboard tile open/close state on the Phone, Computer is OK but phone dashboard tile states not updating ?
Package installer sounds nice after messing with the Nest app and drivers for a week but ended up having to delete as could not get Authenticated, will now have to wait on the google API as I understand it.
iPhone app must have crashed. After I killed the app and then restarted the Dashboard app started working again. Strange some stuff was working like he switch to start the door opener but tile status was not updating. All good now.
