I finally SUCCESSFULLY tied a MIMOlite’s Signal input between my GC2 and SmartThings so a new automated Routine action at the ST hub will switch to Armed state when the MIMO is tripped by the GC2 going into Armed stated. With that ST Armed state I can base a lot of various very powerful actions within SmartThings (incl. IFTTT) that Alarm.com cannot even do.
I also have the MIMO’s relay output on Hardwire Loop 1 so I can have the ST generate an actual GC2 call to Dispatch. But for now I indeed set that sensor to No Response to keep an eye on false alarms for now.
Same setup should work for Vera monitoring the MIMO binary switch. Some lessons learned to share back:
. You must tie MIMO’s SIG+ from GC2 terminal 1 (14VDC+) and SIG- to GC2 term 4 (Open Collector Out). You can’t just tie SIG- alone IF you are powering the MIMO with its bundled power supply wall brick thus no ground loop.
. But if you are also piggybacking the 300 mA MIMOlite from the GC2’s 14VDC power rails (because I have no wall outlet anywhere close by) then things got tricky. Keeping SIG+ tied to +14V caused the MIMO to switch from 0.0V to +14V once, but it remained +14V forever
. Just tying on SIG- to GC2’s OC would not work, either. Waited (forever) to hear from MIMO Support and they said it’s because of the pull up their DSP chip does to handle analog monitoring. They were stumped so I finally ended up buying a dry relay from Amazon to tie GC2’s terms 1 and 4 to and let that simply short the MIMO. Can’t fit it within the MIMO’s case so nice little ugly humpback somewhat protected by wrapping electrical tape. So wish I did not have to do that.
. With the pullup the MIMO’s device driver for the ST Hub considers 2.7V sufficiently “open” while 0.0v is “closed”.
. As mentioned, I set Hardware Loop 1 sensor type in Q1 to (23) No Response Type. Then I went into Alarm.com to explicitly monitor this new Sensor’s state to watch for false alarms for now.
One of the first things I wanted to do is tie my Zwave garage door to an alarm condition since Zwave devices cannot generate alarms on GC2. I also have a Dome chime/siren in the garage and want it to chime nicely and low as soon as the door opens for reasons twofold - #1: Lets an intruder know something is about to go down and to just get out now, #2: Reminds my wife the alarm inside is actually set and not dilly dally. Then after X mins the ST hub switches to Alarm state, sets off all sirens directly, takes camera pics, sends texts, sings “Bad Boys” (and all the crazy customization ST can do ), and can then potentially have GC2 call Dispatch. So far works great!
