Set datapoint value via mqtt

ESPHome
1

Struggling with this one, any pointers much appreciated:

I have a WiFi Tuya (esphome flashed) siren, the issue I am having is setting the tone option, I wish to send a value to a known datapoint but cannot for the life of me make it work.

These are the data points availaibe:

siren_2/debug [C][tuya:023]: Tuya:
siren_2/debug [C][tuya:032]:   Datapoint 104: switch (value: OFF)
siren_2/debug [C][tuya:032]:   Datapoint 113: switch (value: OFF)
siren_2/debug [C][tuya:032]:   Datapoint 112: switch (value: OFF)
siren_2/debug [C][tuya:032]:   Datapoint 114: switch (value: OFF)
siren_2/debug [C][tuya:036]:   Datapoint 101: enum (value: 4)
siren_2/debug [C][tuya:036]:   Datapoint 115: enum (value: 0)
siren_2/debug [C][tuya:036]:   Datapoint 102: enum (value: 0)
siren_2/debug [C][tuya:036]:   Datapoint 116: enum (value: 0)
siren_2/debug [C][tuya:034]:   Datapoint 103: int value (value: 10)
siren_2/debug [C][tuya:034]:   Datapoint 105: int value (value: 311)
siren_2/debug [C][tuya:034]:   Datapoint 106: int value (value: 28)
siren_2/debug [C][tuya:034]:   Datapoint 107: int value (value: 18)
siren_2/debug [C][tuya:034]:   Datapoint 108: int value (value: 27)
siren_2/debug [C][tuya:034]:   Datapoint 109: int value (value: 45)
siren_2/debug [C][tuya:034]:   Datapoint 110: int value (value: 80)

And this is my base setting:

uart:
  rx_pin: GPIO3
  tx_pin: GPIO1
  baud_rate: 9600

tuya:

switch:
  - platform: "tuya"
    name: "alarm"
    switch_datapoint: 104
    
sensor:
 - platform: wifi_signal
   name: "WiFi Signal"
   retain: false
 - platform: "tuya"
   name: "power"
   sensor_datapoint: 101

I know datapoint 102 is the value I need to change, I require a method to send it an integer value via mqtt, every option I have tried had not gone well, would be very grateful if somebody with greater esphome fu could help guide me…

alrighty… in case someone else happens across this, I made it work like this, it’s ugly but functional -

There HAS to be an easier way to set a DP in the Tuya integration…
