|
|
|
The ``mqtt_subscribe`` sensor platform allows you to get external data into ESPHome.
|
|
The sensor will subscribe to messages on the given MQTT topic and parse each message into
|
|
a floating point number.
|
|
|
|
Please note this component only works with MQTT topics that have numeric data! Each time
|
|
a message that is not a number is published a warning will be shown. Please use the MQTT subscribe
|
|
text sensor for importing arbitrary text into the ESPHome ecosystem.
