Meshtastic-python
A python client for using Meshtastic devices. This small library (and example application) provides an easy API for sending and receiving messages over mesh radios. It also provides access to any of the operations/data available in the device user interface or the Android application. Events are delivered using a publish-subscribe model, and you can subscribe to only the message types you are interested in.
