Yes, I got the device to go into linking mode. I can link it to other devices, or to the hub. Not the ISY 994i Both of the sensors that were working, are now not working. I have deleted them and tried to re-add them, and get "Cannot determine Insteon Engine". With Old software, auto detect didn't work and I recall that I had to select a different device to get it to work. Can't find the email I have tried auto detect, and 2845-222 and both give "Cannot determine Insteon Engine" Pretty large system, 24 devices,10 long programs. Don't want to start over.

Found a thread on linking mode. Got it to beep, Still get "Cannot Determine Insteon Engine"

Ok so. 1. How to put the hidden door sensor in "linking mode" it isn't in user guide. It shows how to add it as a controller and remove devices it controls. That works fine. 2. Now that I upgraded to 4.4.5 the Garage Sensor quit completely from the 994i. Both still work on Insteon Hub fine.

994i Running 4.3.26 UI and Firmware. I have two 2845-222 Hidden Door Sensors. They were working and then after the batteries died one went stupid. I have replaced the batteries, and they both add fine to insteon hub, but not the ISY. The first one "garage door" reloaded and works fine. The second one, "Front Door" doesn't work. The docs for the Insteon Hub are easy, click "Add" and then press button until it adds. For the ISY, I see all kinds of notes about making sure you have the right firmware and it is close to a dual band switch. It is 3' from a dual band switch, and the "garage" is 12'. When I attempt to "auto discover" I get the "Unable to add device" "Unable to determine Insteon Engine" I know I had this issue when I first bought these, and thought I kept notes, but I can't find anything. I recall it being something about adding them as a specific device that isn't a "hidden sensor" and not to use "Automatic discovery", but I have tried all other sensors, same results.
