HomeKit won't forget an accessory

This is about HomeKit, but there is no Topic called HomeKit and I had to choose something, so I chose "Using iPhone."

I removed an accessory (Sensi thermostat) and tried to re-add it, but Homekit insists the device is still added. I then removed all my accessories, deleted my home, and deleted the app. I reloaded the app, added a new home, and tried to add the accessory and it still says it is already in HomeKit. How can I get HomeKit to forget?

iPhone 12 mini, iOS 15

Hello Solstice2022,

It sounds like you've removed all HomeKit accessories, but when trying to re-add a thermostat, it says that it's already been added to HomeKit. We're happy to help.

To start, make sure the device you're setting up HomeKit on is running the latest software version:

1.) Back up your device using iCloud or your computer.

2.) Plug your device into power and connect to the internet with Wi-Fi.

3.) Go to Settings > General, then tap Software Update.

Update your iPhone, iPad, or iPod touch - Apple Support

If your device is already running the latest software version, you may want to try resetting the thermostat to factory settings. This article from the manufacturer provides steps for doing so:

One reset, let us know if you're able to add the accessory successfully.

Take care.

You're most welcome, Solstice2022,

Is the set up code you're using the code that appears on the thermostat screen? If so, you may need to also reset your Wi-Fi network. You can learn more here: Thermostat Connection Failure: "Couldn't add Sensi" Error

We hope this helps.

Cheers!

Yes, it's the same set up code as on the screen (I just take a pic of the QR code). And yes, I also did reset my wifi network. Right now, I've decided to give up on getting the thermostat into HomeKit until some upgrade happens. I still have the Sensi app and that works fine.

Thanks for your help!

Thank you. I did do that and was able to get past the "accessory already added" but then it told me the set up code was invalid. It's the same thermostat I had in HomeKit before.
