TS004F - SmartKnob Payload - ERS-10TZBVK-AA

[alanmgomes]

I just bought a new smart knob (https://www.aliexpress.com/item/1005003723886310.html?spm=a2g0o.order_list.0.0.1a441802BbPzMC), its my first, so i dont know if its ok, but i found some weird behavior on action report.
Somehow all actions are reported with a weird payload, like this:

MQTT publish: topic 'zigbee2mqtt/SmartKnob/action', payload 'hold'

I think it should be like this:

MQTT publish: topic 'zigbee2mqtt/SmartKnob', payload '{"action":"hold","action_rate":null,"action_step_size":null,"action_transition_time":null,"battery":100,"brightness":192,"linkquality":167,"operation_mode":"event","voltage":3000}'

But sometimes I get it this way:

MQTT publish: topic 'zigbee2mqtt/SmartKnob', payload '{"action":"","action_rate":null,"action_step_size":null,"action_transition_time":null,"battery":100,"brightness":192,"linkquality":167,"operation_mode":"event","voltage":3000}'

This way, zigbee2mqtt reports an empty string instead of the value.
Does anyone have an idea how to fix this?

Here are some logs:

Hello @alanmgomes,

I am having exactly the same issue. I had no problem pairing the device but I can't do anything else with it. Every time I perform any action with the switch I get this in the zigbe2mqtt log:

Zigbee2MQTT:info  2023-10-31 22:39:34: MQTT publish: topic 'zigbee2mqtt/0x187a3efffefa84b4', payload '{"action":"single","action_rate":null,"action_step_size":null,"action_transition_time":null,"battery":100,"linkquality":57,"operation_mode":"event","voltage":3000}'

Zigbee2MQTT:info  2023-10-31 22:39:34: MQTT publish: topic 'zigbee2mqtt/0x187a3efffefa84b4/action', payload 'single'

I have checked in Home Assistant and it seems that with every action performed, the smart knob publishes 2 topics, one with the action performed and another one empty.

Have you, or anyone found the way to solve this?

Hi @jamferfer, yeah it´s a normal beahivour. After any action its is automatic reset, its not a bug, its a feature;
If you go to Homeassistant and check the logs, all the actions are send/capture.
U can make any automations using the states, single, double, etc, and should work.

It is a normal behaviour ;)
