Tradfri 5-button remote events not registering with ZHA

Configuration Zigbee
,
1

I am using HA core 2021.7 with sonoff zigbee controller using tasmota firmaware and ncp_uart_nsw version 6.7.9. I have other zigbee devices working fine and now I am trying to pair the IKEA Tradfri 5 button remote. The pairing appears to be successful but I only see a single entity for battery power under the device.
I tried listening to zha_event from developer tools but I don’t see any events while pressing buttons on the remote. I enabled all zigbee logging and I do see this on the logs:

2021-08-08 11:17:09 DEBUG (MainThread) [bellows.zigbee.application] Received messageSentHandler frame with [<EmberOutgoingMessageType.OUTGOING_MULTICAST: 3>, 65533, EmberApsFrame(profileId=260, clusterId=6, sourceEndpoint=1, destinationEndpoint=255, options=<EmberApsOption.APS_OPTION_ENABLE_ROUTE_DISCOVERY: 256>, groupId=0, sequence=183), 0, <EmberStatus.DELIVERY_FAILED: 102>, b'']
2021-08-08 11:17:09 DEBUG (MainThread) [bellows.zigbee.application] Unexpected message send notification tag: 0

In this log I do see the clusterId value of 6 which corresponds to the power button which is what I pressed, so something is working but the “unexpected message” is probably where something is going wrong.
Any pointers to get this remote integrated with HA is much appreciated.

Hello, I am having the same issue as you described above but with an another Chinese made dimmer switch. Were you able to resolve the issue?

The issue likely lies in how the Sonoff Zigbee controller with Tasmota firmware handles messages from the IKEA Tradfri 5-button remote. To resolve this, update Tasmota firmware, check for and apply relevant Zigbee quirks, and re-pair the remote.
