The MySensors Arduino library handles the wireless radio link and protocol
|
|
between your home built sensors/actuators and HA controller of choice.
|
|
The sensors forms a self healing radio network with optional repeaters. Each
|
|
repeater and gateway builds a routing tables in EEPROM which keeps track of the
|
|
network topology allowing messages to be routed to nodes.

DESCRIPTION
|
|
|
|
This is an example that demonstrates how to report the battery level for a sensor
|
|
using the internal measurement method.
|
|
Instructions for measuring battery capacity are available here:
