I'm pretty good with insteon, but I am getting frustrated with the open/close sensors I have in my garage to detect door open/close. I have the RF receiver in my garage about 10-15 ft. from the sensors. The sensors don't always send clean "on" "off", so I programmed Powerhome to detect ANY burst of signals within a several-second window as a toggle (closed -> open or vice-versa). But things still don't work solidly. Sometimes the sensor sends a blast of "cleanup" a couple of minutes after an event (which gets interpreted as another event). Sometimes a sensor doesn't fire at all. I've even replaced one of them with a new unit and the behavior is the same. I do check the batteries and they're fine (I use lithium ones).
Anyway - Has anyone found better way to detect garage door open/close? I might do better (if I could get them) to put synchrolinc (power sensors) on the Garage door openers themselves :-( Thanks in advance for any clever ideas.
On the synchrolinc modules. Discontinued as you pointed out. If you want to sense the AC motor current. They do make self powered current sensor modules. That have a dry contact relay output. That can be connected to an I/OLinc sensor input to send Insteon On and Off commands. The MAMAC Systems CT-800 is one.0.5A AC to 200A AC sensing current rating.
The SZC23-NO-AL-CH is one I picked up on Ebay. Off hand I do not remember it specification. I believe it has a slight delay in it output. As the internal circuit has to power up from the AC current.
I have seen how to tutorials with the CT-800 on Cocoontech forums. End of dryer running was one.
Sensing the openers AC current would not detect Open or Closed. Only the opener had been run.
