And with this configurations in the switch:
- platform: mqtt

value_template: "{{ value_json.dps['1'] }}"
command_topic: "tuya/switch_1/set"
payload_on: "true"
payload_off: "false"
state_on: "True"
state_off: "False"
optimistic: false
qos: 0
retain: true
and this in the sensors:
- platform: mqtt
name: "Aquecedor_Power"
state_topic: "tuya/switch_1/status"
unit_of_measurement: W
value_template: "{{ value_json.dps['19'] | multiply(0.1) | float(2) | round (2) }}"
- platform: mqtt
name: "Aquecedor_Current"
state_topic: "tuya/switch_1/status"
unit_of_measurement: mA
value_template: "{{ value_json.dps['18'] | float(2) | round(2) }}"
- platform: mqtt

state_topic: "tuya/switch_1/status"
unit_of_measurement: V
value_template: "{{ value_json.dps['20'] | multiply(0.1) | float(2) | round (2) }}"
