Resideo Pushing Automatic OTA Updates for AT&T LTE Communicators

Resideo is currently in the process of pushing automatic OTA firmware updates to all active AT&T LTE Communicators. The updating process is ongoing, and we are not sure how long it will last. You should not notice any changes to your monitoring service or your Total Connect 2.0 account.

If you recall a few months ago, we announced that Resideo was pushing down automatic over-the-air (OTA) firmware updates to LTE communicators. Resideo started with the Verizon LTE Communicators, and now they are updating the AT&T LTE Communicators. This is a very similar update with no major differences.

Just like before, Resideo is expected to perform this update cycle in batches. Units that were registered first will have the update performed first. This will continue in sequential order until all active Resideo AT&T LTE Communicators have been updated. Any new AT&T LTE Communicator activated during this time will be placed at the end of the queue. If an update fails, that communicator will be pushed to the next batch to try again.

Remember, the communicator must be active and connected with the AlarmNet360 Servers in order for the update to go through. Any communicator that is not active will not be able to receive the update. This includes any communicator installed inside a panel that is currently powered off. Try and keep your panel powered on at all times to ensure that the update can go through successfully.

The following Resideo Communicators are affected by this update:

• Honeywell LYRICLTE-A for Lyric Controller
• Honeywell LTE-L57A for L5210 and L7000
• Honeywell LTE-IA for VISTA Panels
• Honeywell LTE-XA for VISTA Panels
• Honeywell LTE-L3A for L3000

It is possible that your panel may reboot as part of the updating process. However, you should not notice any other changes. Additionally, the following Contact ID messages may be generated during the process:
