 | Ecobee thermostats | "As of March 28th, 2024, ecobee is no longer accepting new developer subscriptions, nor are existing developer accounts able to create new API keys. There is no ETA for when they will be allowed again. Existing API keys will continue to function." | 2024-11-15 | Their HomeKit integration still works, so your HA can connect via that. It's less robust than a real connection, though. |
 | Eufy cameras | Per [reddit](https://www.reddit.com/r/homeassistant/comments/1graane/comment/lx4jo79), the community integration is hit or miss due to flakiness on the Eufy side. Disables RTSP if you don't let it phone home for more than 48 hours. Requires disabling a bunch of security stuff to access the RTSP stream even when it _does_ work. | 2024-11-15 | None |
 | Genie Aladdin Connect | Removed their API access citing licensing issues, supposedly a fix is on the way, but it's been months now and they seem to be letting it [die quietly](https://www.reddit.com/r/homeassistant/comments/1dutam5/aladdin_connect_integration_removed/) | 2024-07-02 | If you don't want to replace the opener, there are two add-on solutions to smarten the opener:<ul><li>[opengarage.io](https://opengarage.io) - Their hardware design and software code (including both firmware and app code) and API documents are publicly available in the [OpenGarage github repository](https://github.com/OpenGarage)</li><li>[ratgdo](https://paulwieland.github.io/ratgdo/) is another solution with open source firmware that works with Security+ 2.0 openers.</li><li>Konnected.io [Smart Garage Door Opener](https://konnected.io/products/smart-garage-door-opener) is based on ESPHome and has an HA integration></li></ul> |
+| GM OnStar | GM changes or voids API keys, which makes it really hard for the integration developers | 2024-11-15 | [OnStar JS](https://github.com/samrum/OnStarJS) is an unofficial NodeJS library to make OnStar requests. Instability is because the devs have to chase GM changes. |
 | iRobot Roomba j7 | Per [reddit](https://www.reddit.com/r/homeassistant/comments/1graane/comment/lx4d50k), cannot be added directly through the HA integration. | 2024-11-14 | Reportedly you can use [koalazak/dorita980](https://github.com/koalazak/dorita980) to hack it into compliance, but it doesn't work with the stock roomba integration |
 | Mazda. Yes, Mazda. | The Home Assistant Blog has the [details](https://www.home-assistant.io/blog/2023/10/13/removal-of-mazda-connected-services-integration/).<br>TL;DR they sent a cease and desist order to the Mazda Home Assistant Integration's Author | |
 | Philips Hue | Philips is forcing users to "upgrade" to a version of their Philips app that requires login to a cloud account. See [How-To Geek](https://www.howtogeek.com/philips-hue-will-soon-require-online-accounts-to-control-lights/) | 2023-11-07 | Use a generic Zigbee coordinator instead of the Philips one |
