So I have been having issues as i started expanding my system with Smart thing v2.
Basically when i purchased the hub I only had 5 devices mostly zwave. After buying a new house I have been slowly replacing bulbs in my house with Sengled element classic A19 and BR 30 bulbs. What I have noticed is that after adding 30, 40 devices including 30+ bulbs my smart hub wont recognize any new bulb. Also some of my bulbs stopped responding properly.
I added a smartthing outlet which I believe works as a repeater as well. Once I added I noticed I could add few more bulbs( 5 to 6) But i still have over 20 bulbs that I am unable to connect. I got so frustrated I called home depot , Sengled customer service and got roiutine answers(Try resetting the bullbs) didnt help.
Out of frustration I removed all the devices from my app, deleted location, deleted routines and reset the hub to factory setting. Now one device that was especially painful to add when i had 40 devices was the smart things multi purpose sensor. I tried adding it as the first thing, It added without any issues. After pairing about 31 more bulbs (total 32 zigbee devices) my hub stopped looking for any more zigbee devices. Which was weird as earlier I had a lot more devices added, however until now I had not added the outlet.
I called smart things customer service and after some troubleshooting here is what the rep told me " There is a limit of 32 direct zigbee connection to SThub". I though that was strange as i Had about 40 + devices earlier. The rep told me to add a repeater, I removed one of the bulbs and then added the outlet. Then tried to pair more bulbs and it worked (for about 6 to 7 bulbs) now again its not adding any more bulbs. I have even tried adding bulbs literally next to the repeater and hub still it just does not want to recognize any new bulbs.
Has anyone else seen this issue? Is there really a hard limit of 32 connections with the hub? Any suggestions?
