Hi everyone - posting a new topic just in case people miss the update in the original discussion (Logitech's stance on local APIs),
I am on the Harmony team with Ian and Todd.
I’m pleased to announce that our latest Harmony mobile app update, version 5.6 for iOS and Android, along with Harmony firmware version 4.15.250, will begin rolling out this coming Friday, February 15, 2019. With this mobile app update and latest firmware release, XMPP is now an option in the Harmony mobile app. By default, Harmony firmware will keep XMPP disabled, but via this new setting, motivated users can enable it.
For those of you already using the special firmware version 4.15.210 with XMPP access, when your hub upgrades to 4.15.250, you can easily re-enable it by following the instructions posted here. You will not need to use the cumbersome firmware update process as you did in December. If you experience any issues, please let us know in our forums. We’ll do our best to respond quickly and sort it out.
Going forward, future firmware updates will respect your current setting, so this should be a one-time action on your part.
For anyone interested, on March 3rd, an engineer from cyber security firm Tenable will be giving a talk where he will describe his experience exploring potential vulnerabilities with Harmony Hubs. It was Tenable’s research and communication with us that originally led us to the potential risks.
Happy Home Automating, everybody
