ALERT ! Harmony Hub firmware v4.15.206 breaks/removes local network control

stay at or downgrade if possible to vers .201

Hey guys and gals caught this on reddit. Luckily mine had not updated yet. so i blocked access into as well as out of my network from the address at the following links via tomato router firmware . I am sure any firewall rule would work as well. Hopefully this works as i can’t find a way to turn off auto updates on the harmony hub.
Hope this saves some of us some headaches!

Do you have the reddit source?

This is not cool. I just brought a new harmony elite that came with a hub purely cause Home Assistant can control it. If this is the case, I’ll be returning it as it’s no longer fit for use.

Mine must have upgraded over night as they are now at .206 and no longer work. I am going to try downgrading and then blocking those URLs.

For what its worth I opened a harmony support case that will likely go nowhere. I am also following this thread which also will likely go no where:

Had to call home and have my wife unplug it before it updates. Not happy with these clowns.

I just finished reading through that. There’s a lot of cranky people there. Someone from Logitech has acknowledged what’s going on, but as yet, not update from them.

I really hope they fix this one way or another. I love the Harmony product line and have just brought a Harmony Elite with a hub cause it work with HA. Worst case I’ll be getting a refund and buying a Broadlink RM Pro.

My hub is still on 4.15.193 and luckily still working as I wanted.

I wasn’t aware that it autoupdated. As you can see, I’m a few versions behind. Is there a setting for that?

I’ve blocked myharmony in Pi-Hole. Should that do the trick when just entered as a wildcard?
