Question

What is everybody's opinion SORRY (factual limit)? what is the max amount of devices to have on one smart hub?  

Answer 1

I have about 80, I ha e 2 SmartThings hubs

Comments

Do you find it helps having the 2 hubs.

@howie the ground floor of my house is very spread out and we have some extremely thick walls made of stone, I found I had to put one at each end of the house to get everything to work properly. I'm sure if I had more devices I'd be OK as I'd have more of a mesh, but still everything works fine now, I'm very impressed with the stability and the fact that I didnt have to do anything special to mesh up a v2 and v3 hub in the same account

---

I had to do the same with my mesh wifi

---

@synthetic5778 whos mesh you using?  

---

Ubiqity, couldn't rate it high enough to be honest!  

---

Would have got SmartThings mesh if it was available in the UK, american WiFi uses channels that are banned in the UK so didn't want to get them imported

---

You made the better choice, I am running the Amplifi HD right now, but thinking of moving to the Amplifi UDM as the HD don't use MU-MIMO and its causing me problems.

@howie yeah, heard mixed reviews tbh on those, they look the part! I used install and configure Cisco Meraki in corporate environments, nothing better, but their licensing model is scandelous at best!  

Answer 2

SmartThings website says: Z-Wave: Up to 232 devices. The controller counts toward the total number of devices on the network; in other words, up to 231 devices could be connected with a single SmartThings Hub. ZigBee: ZigBee networks do not have a concrete limit on the number of devices. Some users may have hundreds of devices, or more, on a single network. However, larger networks will require wireless repeaters to ensure connectivity and optimal signal range and strength.  

Answer 3

I’m up to 110 with no issues.  

Answer 4

I think the v2 hub can have 32 zigbee devices connected directly to it, but you can expand that number with repeaters.

Not true. I have 40 Zigbee devices on my V2 hub. All working without a hitch.

@juxon Check your facts. At least 9 of your devices are connected to an AC Zigbee repeater and not directly to the hub. The limitations of Zigbee nodes are well documents.

@juxon He said with repeaters. Devices powered by mains will typically act as repeaters. Smart bulbs, smart plugs, etc. I can attest to the 32 device limit when I kept ramping up the amount of Sengled Zigbee bulbs in my house, not realizing that Sengled (for some unknown reason) intentionally stops their bulbs from acting as Zigbee repeaters. I was having devices drop off and not be able to reconnect them and was having a hell of a time figuring out what the issue was. Once I realized the issue, I replaced a few Sengled bulbs with SmartThings Zigbee bulbs (which are excellent repeaters), and have never had a problem since. I've got over 100 devices now (including a number of Xiaomi Aqara sensors which are very finicky about how they are connected) and I have no issues. If you go into the SmartThings IDE on your computer and click on the details of a Zigbee device, you'll see a "next hop" attribute, which tells you the device your thing is connected through. In your case most will say the Hub, but I guarantee that some will repeat through another device you may not even realize is acting as a repeater.

@parcenary894 That is an issue with most Zigbee bulbs, bulbs make terrible repeaters in the mesh. Even my Sylvania bulbs I had to make sure I had them at the end of the line or everything went haywire. Sengled was wise to just disable it by design.  

---

@supine As I mentioned in my post the SmartThings brand bulbs are excellent repeaters.  

Answer 5

I think I have about 150 physical devices and total of around 300 with smartthings. For the most part it runs well, but I think I have too many automations because some of my local automations sometimes take a couple of seconds to run. I'm thinking about getting a second hub or moving to a different system because its just too much for one ST hub to handle sometimes.  

Comments

I'm in a similar boat. I have 310 devices according to ActionTiles at last check.  

Answer 6

And counting

Answer 7

Max devices is not an “opinion” It’s a factual limit as @erotica said above.  

Answer 8

To the super brains that keep pointing back to @erotica thank you I have read it and don't need telling where it is smh

Answer 9

My car has a seating capacity of 7 people, but it drives much better with just one.
