Zigbee Lighting being overwhelmed

I have had a lot a success with Zigbee for lighting but I have noticed a small issue. If I keep pushing all on then all off rapidly it overwhelms something and stops working until it catches up. This is a really minor issue and I do tell my customers to simply wait a few seconds between presses. In all reality this is never done expect to demo the lights and the system can take a few on/offs before it stops working.

This issue does not exist with the Lutron bridge Caseta or RA2 so it is probably related to the Zigbee module.

The zigbee radio is a serial radio that accepts/sends data with a max throughput of 250 kbps. I imagine that data transfer is asymmetric, so a maximum net rate of ~125 kbps in each direction. I would guess that rapid state changes can overwhelm the radio and increases noise from re-transmits etc.

However, as you correctly point out, this is a testing only scenario.

I would agree with you. It is not something I worry about other than telling people that with the ALL ON/OFF feature wait a few seconds between pushes.

Out of curiosity, What "ALL ON/OFF feature" are you referring to here?

In this installation; I use a Lutron Pico to turn ON and OFF/Change Color for all of the Zigbee lights; 10 INNR Zigbee bulbs on a dock posts....see picture above.

Are you using zigbee group messaging for this? Because it seems like an ideal situation to use ZGM. Using it will reduce zigbee traffic for the on/off commands substantially.

Yes. I love Zigbee Groups. The popcorn effect is not desired and a Zigbee group solves it.

Just be aware that ZGM is not a cure-all... It works great for all on or off, or setting all respective bulbs to the same color & level... ZGM shouldn't be used if you're doing unique things per bulb (power, color, level). I realize your use-case here is good-to-go; I'm just mentioning that here for posterity.

It keep my INNR bulb in complete sync. I can change levels and colors and it all works at exactly the same time without any delays.
