I’ve been trying to see what I’m doing wrong with my IKEA TRADFRI remote control setup. I’ve linked the remote via Zigbee2MQTT, yet I’m unable to get any of the blueprints (including this one) to yield the mapped button behaviors.
This is my setup:
I am currently updating the firmware, but I’ve read the current update doesn’t impact the remote itself.
Do you see anything off with this config? Would appreciate any insights on how to troubleshoot! 
I have the same remote but am using it with ZHA and this blueprint…

I had several issues when 2022.5 was first released but it has been pretty stable since 2022.5.3
I’ve tried with ZHA as well, and I can’t get HA to recognize any information about the remote, not even the battery level. I just purchased new batteries and trying that now with Z2M.
Did you ever get this remote to work?
