Homekit: Accessory Already Added Issue?

Having the same Issue with an August smart lock I installed yesterday. Went through the pain of deleting my home and everything. I was able to add every accessory back except the smart lock..Not sure if there is a resolution but it’s very annoying!

After hours and hours, I just got the yale lock working in HomeKit. The trick is, dont use the bridge. The Yale/August lock seems to work perfectly without the bridge. I was unable to get the locking working in HomeKit with the bridge connected. Factory reset the lock and install without bridge.

Hi everyone. Really hope this helps...

I struggled for weeks with this as well. Tried everything you can think of, so I called AppleCare.

they called me this morning and walked through all possibilities.

this is actually not a HomeKit issue. It was a hardware issue.

I finally got it working by doing a full factory reset.

I opened the back plate, took out all batteries, left the august module in place.

you will then need to unscrew the two screws where the batteries were, as well as the bottom screw.

when you move the battery plate, you will see the board underneath.

roughly in the Center of it you will see a white button. This is the hard reset button.

you have to hold down for three second. Then while still pressing and holding it, you need to put the batteries back in.

you will here the Yale lock turn on.

this has successfully factory reset it.

then I found something funny. I couldn’t setup the august connect properly from the Yale app. I had to use the august app instead, weird.

anyways. I hope this helps.

cheers

Well here we are 25 days later and no replacement module. Multiple calls to Yale and I have now been told that they were out of modules and miracle of miracles they just came in and they will send one today.

I have not tried playing with it again - but having read some of the more recent posts, I may try one more time while I am waiting for a module.

Exactly the same issue with the Sensi/Emerson touch thermostat. Just won't re-add itself to Home kit, no matter what - have reset and re-added it several times to the Sensi App. I don't want to create a new home because I have many 40 devices connected to Home Kit, and a ton of custom schedules for art lights, blinds etc. Two of the other Sensi/Emerson thermostats in my unit (there are three) are working just fine with Home Kit.

Same issue here. with my Emerson Sensi Touch thermostat. Tried setting up a new Home and still got the same message "Thermostat Already Added To Home" Thermostat works fine on Sensi app. Just no longer shows on Home. I am pretty sure this is an issue with Homekit.

Is there a way to reset the ecobee to factory default?

Try this:

From the Home screen, press Menu.

Select Settings.

Go to Reset.

Choose Reset All Settings then confirm your selection by pressing Yes.

Choose the reset option that suits your needs: ... 

The ecobee thermostat will be reset to factory defaults.

I grabbed that off the web from a google search. Not sure how helpful it is.

Hope that helps.

Not sure. From my experience, these are pieces of hardware that uses software to configure them. If something happens with the software piece, such as the device locked up, from a device perspective, it got added, however, your software doesn’t see it.

This situation also occurs with Leviton Gen2 dimmers and switches. Home Kit App indicates the accessory is “already added” but it does not appear in the Home accessories list and cannot be controlled by Home/Siri. Apple Support seem clueless on this issue. But it has clearly been a problem for many months.

Same problem , I bought Sensibro air conditional control app , I found some issue on device under Home, I removed it and try to reinstall it again , I can’t ~ it keep saying already installed can’t install again under home . Assume Apple Home issue , any plan to fix this issue ?

This worked for me. The exact steps I took were:

1) Delete the wi-fi module (if you have one) and unplug.

2) Reset the module in the Yale / August app.

3) Reboot iPhone.

4) Remove the batteries.

5) LEAVE THE AUGUST MODULE IN! (not trying to yell, just trying to emphasize where I went wrong!)

6) Remove the screws and reset the Yale lock (hold down the white button and replace the batteries while holding the button down.

7) Setup master lock code and register lock.

8) Add lock to Yale app.

9) Add lock to Homekit though the Yale app BUT I entered the code. I did not use the camera.

10) After successfully adding to Homekit you can add the August Wi-fi adapter if you have one.

I've wasted weeks trying to get this thing to work in Homekit so I hope this helps at least 1 person :-)

Good luck!

Please help!!

I still haven’t found a solution, but I’m hoping if enough of us are having this issue that apple will help :(

Ugh that’s annoying, but at least it’s an answer. Appreciate your following up and adding info even after you got your own resolution!
