Hello, when trying to log into the HCS website, I am receiving the following error message after clicking the ‘Login via Athom’ button. Is this a known issue? Error: `{"code":400,"error":"invalid_request","error_description":"A client with the given ID doesn not exist."}`

It’s deprecated, Kenneth. I’m not sure why it’s still online… You’d use [https://homeycommunity.space](https://homeycommunity.space) instead.  
But certain apps can be found @ Github / Bitbucket and you can install them [by CLI](https://community.homey.app/t/how-to-cli-install-method/198)

Thank you. I have been trying to secure OwnTracks which I finally did but experiencing many rabbit holes trying set it up with AI guidance.

Is this of any use?  
‘Location and Presence’ is the new name for the app to use together with the Owntracks phone app:

This app is based on the Owntracks specification and available apps for Android and iPhone. With the Owntracks app on your phone, you can define regions / geofences. These geofences are coordinates and a radius. These can be your home, workplace or any other place. Based on your username and geofence you can define triggers for Homey (as an example Jo…

Thank you Peter. I have been able to get the Location and Presence app installed on Homey Pro, and it should serve my purpose. My only hiccup now is that I am having some trouble setting up the iOS app which apparently must be configured precisely to “coordinate” with Location and Presence on my Homey Pro. With full transparency, I have been relying on AI to guide me through that process and it’s been one rabbit hole after another because the information I’m getting is either out of date or incorrect. With that said, can you point me to some other source that can guide through the steps to create Home and Away routines for my Nest Learning Thermostat using a geofence. I actually have one set up using SmartThings which works quite well, but naturally my objective is to utilize Homey Pro for these types of automations. Again, thank you for reaching out.

YW!

Perhaps this is a clear(er) howto, and it includes ios screenshots, Kenneth (follow the link to view the full post); _it’s important to disable the ‘Authentication’ toggle_:

So with this post I will show my settings to help others (and I have documentation smiley ) Get HomeyID from settings in Homey Setup user in Location & Presence app in Homey and get user token Setup Owntracks. Fields that I use, see image: Tracker, DeviceID, UserID, URL Make sure the map in Owntracks is in setting SIGNIFICANT to have automatic updates. The URL is created as follows: https://{HomeyID}.connect.athom.com/api/app/nl.scanno.owntrack…

Can’t help out with Nest!
