Sorry, can't remember....  I've gone over to micropython on esp32 now so can't even go back to check - good luck!  Cool

I had this working a few weeks ago.
an extract from my notes ...

Can send over MQTT by using
Publish - ESP/cmd with payload/message - LCD,Lin,Row,”text” or value
where ESP is the NodeMCU device name 
Tested by sending from MQTT app on my pc.

Can also publish using Node-Red flow
  1. Config ESP controller to publish data to local or public broker as vessels/self/%tskname%/%valname%
    e.g BoatyMcboatface/electrical/batteries/house/voltage

  2. Use MQTT In Node to input data from broker
    Set Topic to BoatyMcboatface/electrical/batteries/house/voltage
  3. Wire MQTT In node to Function node
    Function node Properties
    msg.payload = "LCD,2,1,WiFi..." + msg.payload;
    return msg;
  4. MQTT Out Node with topic set as ESP Device name/cmd
I plan to fit the LCD2004 to display my tank sensor values
Fuel, Fresh and Black - read by ADS1115/ESP8266

Anyone succeeded in getting sensor data from ESPEASY into SignalK using UDP?

EDIT: I'll answer my own question - Yes I just did !
