2 x Hub 2's and multiple devices.

Hi to you all.

i have a new BT hub 2 and I've just signed with BT Broadband. my connection speed is a measly 10mbps at best so im already punching above my weight with what I'm trying to do. 

due to disabilities my whole house is automated with  tyua bulbs, switches and amazon Alexa all running on the smart life app.  Every room in the house has a cat 6 data port off of a tp link distribution box. . i think I've to many devices (50+) and the hub 2 is struggling. The house network just about worked with my previous sky hub but this one from BT is not coping so well. i have a second older BT hub 2 here from a previous contract, can this be connected into a data port the other end of the house to share the load? I've still 20 more bulbs to connect. can i simply plug it into a data port and use it for Wi-Fi access for all the bulbs? the old hub 2 was running 2 separate signals, a 5 ghz and a 2.4. i used to run all the bulbs at that time on the 2.4 and the phone amazon dots etc on the 5. this new hum doesn't split like the older one. 

How can I use the old hub 2 as a slave to the new one. I'm sorry I'm not very techy so I'm trying to make sense. 

is ther an alternative router to cope with so many bulbs and switches? id like to connect up to 80 devices to really assist my freedom in the house.

Link to setting up a Smart Hub 2 as an access point

If you find that post useful, remember to give its poster a thumbs up!

As you have everything already, you may as well try this.  Modern Tuya bulbs aren't exactly WiFi hogs but, that's a lot of light bulbs!  I might have chosen a system that used a (433 or 866MHz) smart hub in your situation.


I only learn by making mistakes and owning up to them - boy do I learn a lot!

Re: 2 x Hub 2's and multiple devices.

I’d recommend joining a network oriented forum than an isp support one. Most of the devices you referred to are low bandwidth.
I would very much doubt that your broadband or router is going to be the bottleneck and it sound as though your wired network is up to scratch which means any issues you have could well be down to wireless congestion and/or overlapping channels.

Re: 2 x Hub 2's and multiple devices.

Unfortunately, there is no way to actually share the load between the hubs as such.

There are a couple of options that might help though but there are downsides to both.

You can configure the second hub as explained in the link posted by @Crimliar but your prime hub will still be doing all the routing and may struggle with the number of devices.

Alternatively, you could configure the second hub as a router in a separate subnet to the first but that will have the downside that devices connected to each won't be able to talk to each other so if you control the devices with a phone for example, the phone would need to be connected to the same hub as the device you are controlling.

It might be worth considering a third party router rather than using a BT hub

@spile as you say, I doubt the bottleneck is bandwidth related but could well be the sheer number of IP addresses for the hub to handle.
