Consider using Zigbee2MQTT binding before using this Node-Red flow (and probably only use this if your devices doesn’t support binding)
This is mostly about re-sharing the great work of NotEnoughTech (IKEA TRADFRI Wireless dimmer in NodeRED - NotEnoughTech), and also about some minor tweaks I did to:
- Make it work with the latest versions of software and/or hardware.
- Payload and button events did not work
- Be able to use it as a subflow with multiple lamps and remotes.
- Replaced hardcoded light and remote with subflow environment variables.
Here is how to use it:
And here is how the subflow looks:
And the code:
