TuyaMQTT

Listens on MQTT topic and routes requests to Tuya devices, based on a one to one topic translation.

MQTT Topics

tuya/<protocol>/<device-id>/<device-localkey>/<device-ip>/<dps>/state
tuya/<protocol>/<device-id>/<device-localkey>/<device-ip>/<dps>/command

MQTT state

State payload values can be set in tuyamqtt.conf. Updates on command, or on state change on device (5 second polling)

• Default values: ON, OFF

MQTT command

Valid values are true, ON, 1, false, OFF, 0

MQTT dps attributes

Returns dps state, via state and timestamp

MQTT attributes

Returns all device attributes, via state and timestamp. Updates on command, or on state change on device (5 second polling)

MQTT availability

Availability payload values can be set in tuyamqtt.conf. Updates every 15 seconds.

• Default values: online, offline.

Via state

The via state can be used in your home automation system. i.e. a state change with via tuya could be a strong indication of presence Returns mqtt when a state change comes in via a mqtt-request Returns tuya when a state change is detected in status polling

Home Assistant Example

switch:
  - platform: mqtt
    name: "Living Socket Left 1"
    command_topic: "tuya/3.3/34280100500194d17c95/e7e9339dd82abe61/192.168.1.50/1/command"  
    state_topic: "tuya/3.3/34280100500194d17c95/e7e9339dd82abe61/192.168.1.50/1/state"

    availability_topic: "tuya/3.3/34280100500194d17c95/e7e9339dd82abe61/192.168.1.50/availability"
  - platform: mqtt
    name: "Living Socket Left 2"
    command_topic: "tuya/3.3/347550642cf432a2cbaf/314c6b7f3f44f979/192.168.1.51/1/command"
    state_topic: "tuya/3.3/347550642cf432a2cbaf/314c6b7f3f44f979/192.168.1.51/1/state"
    json_attributes_topic: "tuya/3.3/347550642cf432a2cbaf/314c6b7f3f44f979/192.168.1.51/attributes"
    availability_topic: "tuya/3.3/347550642cf432a2cbaf/314c6b7f3f44f979/192.168.1.51/availability"
  - platform: mqtt
    name: "Living Socket Right 1"
    command_topic: "tuya/3.3/347550712cf432a2b04a/f9b80165db5e06bd/192.168.1.54/1/command" 
    state_topic: "tuya/3.3/347550712cf432a2b04a/f9b80165db5e06bd/192.168.1.54/1/state"
    json_attributes_topic: "tuya/3.3/347550712cf432a2b04a/f9b80165db5e06bd/192.168.1.54/attributes"
    availability_topic: "tuya/3.3/347550712cf432a2b04a/f9b80165db5e06bd/192.168.1.54/availability"

• Note: availability only works for devices known by TuyaMQTT.

Testing with Mosquitto

Use mosquitto_pub to make TuyaMQTT aware of the device. TuyaMQTT needs a topic ending with command to discover a device

mosquitto_pub -t tuya/3.1/34280100600194d17c96/e7e9339aa82abe61/192.168.1.50/1/command -m ON

And run mosquitto_sub to listen to updates (in another terminal).

mosquitto_sub -t tuya/3.1/34280100600194d17c96/e7e9339aa82abe61/192.168.1.50/#

It might take a few seconds to get a state update.

Note: that TuyaMQTT only pushes status message when there was a change. The availability topic should be published every 15 sec.

Debugging

python3 -u main.py -v
python3 -u main.py -vv
python3 -u main.py -vvv

TODO

• check config values
• device config via topic is rather crude
  • simple interface?
• implement https://www.home-assistant.io/docs/mqtt/discovery/

Changelog

• replaced entities.json with sqlite db
• only publish onchange
• added via mqtt/tuya
• thread per device
• pytuya replaced by https://github.com/TradeFace/tuya

Acknowledgements

• https://github.com/SDNick484 for testing protocol 3.1 reimplementation
