Had an old garage door opener that Sense found reliably. Then it died 
. Got a new one (LiftMaster) with WiFi (love it). The app tells me every time it moves (see image) Problem Statement: Sense keeps finding the old opener (no new activity since it was removed) and wonât find new signal. Some have theorized itâs due to the âsoft startâ of the new devise. Any ideas on how to permanently kill old signal ID and find new one?.
I had the same problem with a garbage disposal, which it found again last week two or three months after we replaced it 
I just delete it each time it shows up.
I have the Craftsman version of your garage door opener, basically the same except for the badging, and after a year itâs not been found. Itâs a pretty low demand device, so Iâm not too concerned that it hasnât been IDâd. Iâm more upset the API for Craftsman is restricted and we canât tap into it with Smartthings.
@mstraka606 Just to clarify, did you delete the old device in the app? If not, I definitely recommend doing so.
Given that Sense does look at recent historical data to identify devices, it may get re-detected for a little while unfortunately. Deleting the old device does give the system a better opportunity to learn the new one vs conflating it with the old opener, though. This is an issue weâre aware of and do plan to address.
Hi Ben. Yes, Iâve deleted it twiceâŚwill do so again.
NJHaley you are so lucky! I long for the day when Sense finds 1 of my 2 garbage disposals (or washing machine, clothes dryer, âŚyou get the idea). I havenât had a meaningful âfindâ in months. Did you do something other than delete those devices? Also Iâve heard this section of the app isnât workingâŚcan we get rid of it then?..itâs giving me false hope of great things every time I look at it. 
The garbage disposal was one of the first things it found - hang in there. What brand do you have? I started with an insinkerator which was pretty quick, the Moen replacement took a little while. I just keep deleting things when it refinds them. I suspect that either the new stove or heating element might be our old dishwasherâŚprobably the heating element. I think the new stove might be a crock pot we were using this week.
Weâve had pretty good luck with device identification. I wonder if itâs because we have a relatively simple house. 2100sqft, two adults and a child, just one of each appliance, etc. Itâs only found the initial spin of the washer, but itâs found two different parts of the dryer. We just picked up a new smart TV so Iâm excited to see if it can find it with the network detection feature.
I agree about the device detection section - fix it or delete it. Preferably fix it because it would be a useful feature if it worked.
@mstraka606 and @NJHaley, I apologize for any frustration with that âDevice Detectionâ section. Weâve been discussing some fixes in that regard.

Thanks BenâŚno worries. Iâm (obviously) patient! While I have you in the detection topic. How do I get sense to realize that there are 3 separate devices in this signalâŚhot tub heater and clothes dryer?
Hmm, this isnât an already detected device, right? Those devices just havenât been detected yet?
Ultimately, itâll come down to improvements to our detection algorithms. Hot tub detection is something we know needs some improvement. If the devices are being incorrectly conflated in some way, you could use the âdevice is not onâ feature or delete the device. Sometimes deleting a device that is getting conflated with another helps the device get more accurately re-detected. Wish I had a better âaction itemâ here!
Ok I deleted that device (identified it correctly as a heater). Hopefully
it wonât conflate again. 
Ben. Sense found my Hot Tub heater and the pump on low and high speeds and has been solid for the past week.
