Hub Firmware Beta 0.26.x

Hey everyone!

We’re excited to announce the start of a new SmartThings Hub Firmware Beta. Version 0.26.x will begin rolling out in batches starting June 4th; we will send out an email when we start updating Hubs. We will be paying close attention to any issues encountered by users so your hub may not get updated right away. The hub will be offline for about a minute during the update. See below for more specific details about the update.

Hub Targets

  • Samsung SmartThings Hub 2015 (Hub V2)
  • Samsung SmartThings Hub 2018 (Hub V3)

Release Date

  • June 4th

Release Notes

This still planned for tomorrow?

Yupper! We’re still looking good over here.

@schulz so you’re aware, there seems to have been some kind of cloud side change/issue recently that is causing masses of devices going into HUB_DISCONNECTED status. I don’t know if you guys want to wait for this beta until after this is resolved so the waters aren’t muddied trying to debug problems.

Flip the DTH to reschedule the device check.

rebooting the hub always brings them back. Flipping the DTH on 40+ devices would be a PITA.


Thanks for the heads up. We’ll look into it.

How long has this been going on?

A couple days ago is when I first noticed.

I hear ya. Never had more than a few. Hub reboot didn’t seem to fix it for me, but I’ll try it again tomorrow (after the new rollout :wink: - that’s when mine usually flip to HUB_DISCONNECTED)

Remember that they are rolling out in batches so you may not get it right away

My hub is wide open, they can do it whenever they want to, …wait, I have no control over that LOL

Technical difficulties have delayed the release until tomorrow. Sorry for the inconvenience - we’ll be going first thing in the morning (U.S. Central Time)


Received my update

Just received 26.5.

Any details on which models so we know what to test?

I had to hit refresh on Hue bridge, as it showed offline and so were all my Hue bulbs. But other than that no HUB_DISCONNECTED devices.

It includes recent products from Innr and Aurora Lighting


received the update, all looks good so far, no disconnect status here…

One hue bridge and all associated lights are showing “unavailable “. But I can still control the lights. :slight_smile:

I think those are european brands?

What about makes/models for testing this?

See my post above yours, just hit refresh on the bridge tile in ST classic app.
