Flow Details

This nodered flow will get the bitcoin price in USD from the coingecko API and shows it on your awtrix light matrix.


  • Modify the MQTT broker (Server) in MQTT Out Node: awtrix/custom/bitcoin
  • Keep the inject node around 10 minutes to not trigger the API limit from coingecko.
  • It is possible to change the currency from USD to another currency by editing the change node in the flow. Modify the msg.currency value. All possible currencies can be found here
