Note:
1. Please be sure you have read the Beta Test Agreement before upgrading the Pre-release firmware!
2. It is recommended that all Decos in the network be upgraded to beta firmware.
3. Please also check whether there is a firmware update for the Tapo device in the Tapo APP. If so, please update the Tapo device to the latest firmware.
4. How to update the satellite Deco units:
When the satellite Decos are offline, they may not be successfully upgraded through the Web UI. In this case, it is recommended to upgrade according to the following steps:
- Please temporarily power off most of the smart home devices and wait for the satellite Deco come back online.
- Once all the satellite Deco units are confirmed online, try upgrading to the beta firmware again through the Web UI.
-If the main Deco and satellite Deco units are on different models, you could also update the satellite units individually through its IP address.
- After ensuring that all Deco units have been successfully upgraded, power on the Tapo devices again and observe if the issue is resolved.

I have been trying to discover for over a week how I could get any of my 6 satellites to be on line.
I have loads of Tapo devices (plugs, switches, buttons, hubs, bulbs) plus Echo devices and Blink cameras and door bells - so the thought of disconnecting them from my M5 so I can install the patch was just a nightmare. However the easy way around was to block individual devices through the Deco App. This meant that they were not part of the network. Once I had blocked 12 I refreshed the deco app and it had proudly said "Everything looks good".
Installing the patch was just a case of downloading and unzipping the file. No problems. I had already read the instructions on this.
I then returned to the Deco app after the network rebooted and went through unblocking a few of the devices at a time and checking to see if everything was ok. Now everything looks good.

Hi, Thanks for the update.
You can check the email address in the message.
And there might be some useful tips regarding Deco firmware upgrades:
1. You could upgrade or downgrade 1.6.2 to 1.6.0 or 1.6.1 directly via web interface. But from 1.7.x to 1.6.x or 1.6.x to 1.5.x which has crossed different firmware platforms, a firmware recovery is needed(such as from the 1.7.0 beta to the 1.6.2 beta on Deco M4_V2 here): How to use firmware recovery
2. The beta firmware is usually based on the latest official firmware and sometimes it has the same version number as the official version, like the 1.6.2 beta for M4 and the 1.1.5 beta for Deco X10. The build number represents its release date, for example, 1.1.5_build_20240910 is newer than 1.1.5_build_20240719.
I see now you have removed Deco X10 from the Mesh system and left the 3*Deco M4 only. Is it because the 1.1.5_20240910_beta caused Deco X10 to fail to connect to the internet service?
Wait for your reply and best regards.

@David-TP After downloading the file according to your instructions, I see that the Deco X10 is updated but the mesh does not connect to the Deco M4 v2 and the main router is disconnected. It's an old version so it's not possible to update... Since I was using X10 as the main router and M4 3-router backhaul was connected by meshing, today it's not possible. I opened Deco X10 and set up Deco M4. When a device goes offline after a while when that device goes online or connects again, it takes a lot of time for IP binding or access is denied. Big brand may give more support to customers but physically I am disappointed.

Hi, Thanks for the update.
Since you are on the 1.7.0 beta, would you mind factory recovery to the 1.6.2 beta in the first post to see whether it helped:
I just updated a new beta version for Deco X10_V1, Please also test whether the beta firmware helps:
| Deco X10/X15/X1500/W4500_V1 | 1.1.5_build_20240910_Beta |
Wait for your reply and best regards.

Hi, since you commented on this post, do you mean the satellite Deco M4 units are solid white, connected via Ethernet cables, but Deco APP reported they were all offline?
Would the mobile devices still get internet connection from these "Offline" Deco M4?
Wait for your reply and best regards.

Hi,
Just to add my brick to the wall;
I encountered the exact same issue, and with this beta firmware, everything is back to normal.
So, I can't wait until it will be officially released :)
Thanks for the support,
Q.
