3. Create flow and publish tuya socket to HomeAssistant
Prerequisete is that you have MQTT working in HomeAssistant in order to publish the data to HA
Install this flow:

And configure it according to your data. Do not forget to configure MQTT IN and MQTT OUT with your MQTT settings (and password)
(I will add more detailed instructions next time)
4. Create sensors and switches
Put the following data into you HomeAssistant configuration.yaml and adjust it according to your data
switch:
- platform: mqtt
name: "Plug1"
state_topic: "devices/tuya/plug1"
value_template: "{{ value_json.dps['1'] }}"
command_topic: "devices/tuya/plug1/trigger"
payload_on: "true"
payload_off: "false"
state_on: "True"
state_off: "False"
optimistic: false
qos: 0
retain: true
sensor:
- platform: mqtt
name: "Plug1_Power"
state_topic: "devices/tuya/plug1"
unit_of_measurement: W
value_template: "{{ value_json.dps['19'] | multiply(0.1) | float(2) | round (2) }}"
- platform: mqtt
name: "Plug1_Current"
state_topic: "devices/tuya/plug1"
unit_of_measurement: mA
value_template: "{{ value_json.dps['18'] | float(2) | round(2) }}"
- platform: mqtt
name: "Plug1_Voltage"
state_topic: "devices/tuya/plug1"
unit_of_measurement: V
value_template: "{{ value_json.dps['20'] | multiply(0.1) | float(2) | round (2) }}"
Add sensors and switches to lovelace and use the created entities in your automations and flows!
