V2/V3 Hub Firmware Beta 51.X

Hub Firmware 0.51.2 Beta

Hey everyone!

We are excited to announce the start of a new SmartThings Hub Firmware Beta. Version 0.51.2 will be our first release for 51 and will begin rolling out in batches starting early this week. This will be a phased rollout so that we can keep a close eye on any issues that arise so your hub may not be updated immediately. The hub will be offline for about a minute during the update. See below for more specific details about the update.


  • 0.51.2

Hub Target

  • Samsung SmartThings Hub 2015 (Hub v2)
  • Samsung SmartThings Hub 2018 (Hub v3)

Release Date

  • **Release Date: Nov 14, 2023

Might there be a similar beta program for Smartthings WiFi hubs? Any reason to be optimistic that those hubs will be updated to a suitable firmware that will enable them to utilize the hub-replace feature?

Hey @henrypscott - I really appreciate your question. We too see the value of a Beta program on the different hub types. Currently, we do not yet offer this, however, I will save this message and if that changes I will personally reach out to you and let you know.

Thank you for this question.

I signed up to the beta on centercode and put as much info on it that it allowed at the start of the previous one but still not been accepted, is this for specific people or am I doing something wrong?

@alissa.dornbos due to repetitive instability in my Zwave / Zigbee network, I’d like to leave the beta program. But I do not remember the account password on https://smartthings.centercode.com/
And it seems the “forgot password” button is not working, is there another way to opt out?

Hello @veonua.

We are sorry to hear about your troubles. Please private message me your email address and I can help you with the password reset steps.

All users who enroll in this program, temporarily get a pre-production release. Then when the production candidate rolls out, those hubs update to the production candidate. If you are having Z-Wave or Zigbee Network issues, please feel free to provide additional information and we could take a look.

Thank you.

I’m seeing a lot transmit failures on the z-wave network with the this beta firmware (it’s not happening on the 0.50.x release firmware)

Hi Alissa,

Same as Veonua, I would like to opt-out from the beta release program as well. One of my hub is now on 51.2 and most , if not all, of my physical devices are going offline for no reasons. But just like Veonua, I am not able to login in Centecode. Please help. Thanks.

I just hope the issue on this beta release gets resolved soon.
