First of all please excuse my bad english!

I have ordered a CC2531 usb stick and want to add several Xiaomi sensors. Maybe later I am going to order some tradfri, osram or other devices. I want to integrate all of these zigbee devices to OH.

As far as I understood there are two possibilities after flashing the stick with the right firmware:

  1. use the OH zigbee binding
  2. use zigbee2mqtt

All of the mentioned devices should work with both variants. So, what ist the benifit of zigbee2mqtt?

Thanks for your help!

I have only used zigbee2mqtt so my input will most likely be biased but I like the fact you easily add any new device without a need for support.

This should also be the case for most ZigBee devices. The binding is designed to automatically detect the channels a device provides, and to add them. “Support” is only required if the device doesn’t report its services correctly.

So, as far as I understood, there is no advantage of zigbee2mqtt. On the contrary, I have to mess around with mqtt, rules and transformations…

Thanks @chris for the info on the zigbee binding.:+1: I’m more a DIY person, and like knowing/seeing all the in’s and out, hence the reason for choosing zigbee2mqtt route.

For zigbee2mqtt you will need to use mqtt and most likely a transformation. The rule option is completely up to you and how you plan to use the devices.

Here’s a zigbee2mqtt item example:

Switch MyLight "My Light"    <light> ["Lighting"] { mqtt=">[pibroker:zigbee/0xb0ce1814030ac279/set:command:*:JS(setZigbeeState.js)],<[pibroker:zigbee/0xb0ce1814030ac279:state:JSONPATH($.state)]", expire="120m,command=OFF" }
Dimmer MyLight_Level "My Light Level"    <light> ["Lighting"] { mqtt=">[pibroker:zigbee/0xb0ce1814030ac279/set:command:*:JS(setZigbeeBrightness.js)],<[pibroker:zigbee/0xb0ce1814030ac279:state:JS(getZigbeeBrightness.js)]" }

This is one, of about 7 mqtt items, that I haven’t converted to the new 2.4 mqtt version but I have plan to do so in the near future. I’ve already found and bookmarked a topic that provides a good example.:wink:

Notice at the end of the Switch item I’m using the expire binding to automatically turn the light off after 2 hours so no rules need for this device to do what I need.:grinning:

The great thing about OH is the flexibility to work and do whatever your home automation needs may be. Use a rule, the expire binding, zigbee2mqtt, the zigbee binding or a little of both.

Best of luck and hope you find what works best for you.
