EventMachine.run do
# Construct device
device = LosantMqtt::Device.new(
device_id: "my-device-id"
key: "my-app-access-key",
secret: "my-app-access-secret")
# Connect to Losant.
device.connect
# Listen for commands.
device.on(:command) do |d, command|
puts "#{d.device_id}: Command received."
puts command["name"]
puts command["payload"]
end
# Send temperature once every second.
EventMachine::PeriodicTimer.new(1) do
temp = call_out_to_your_sensor_here()
device.send_state({ temperature: temp })
end
