UPDATE: Aqara has found a few problems with the 2.2.2 update so decided to remove it to avoid further problems but now a new problem has started - 2.2.3 - which solves the problems that have arisen for those who managed to update to 2.2.2 before it was removed, while adding the extra features and compatibility with underlying devices as originally intended.

akara started rolling out a new one today firmware update for their very popular Smart Camera, the G2H Camera Hub. The new update, which appears to be global, is listed in HomeKit as version 2.2.2, or 2.2.2_0002.0526 in the Aqara Home app, offers the usual bug fixes, but now states that additional devices are now supported. One such device that has since been released internationally was the Aqara TVOC sensor (read our review HERE), which wasn't really fully compatible with the G2H until this latest update, allowing the multisensor to be added to the hub, but unfortunately not being exposed to HomeKit.

With the new update, the TVOC sensor is now exposed to HomeKit and thus fully compatible. Other devices that can now be added to the G2H and exposed to HomeKit include the H1 Wireless and H1 Wired EU Switches, the upcoming Roller blind drive E1, and the Wired and Wireless E1 Switches (the latter two are currently "China only" products).

To update to the latest firmware, login to your Aqara account, click 'Profile' and select Firmware Update to check. If it's not listed yet, it's just a matter of waiting for it to roll out to your region, which should be very soon.

Thanks to Richard B Line for the heads up.
