Sample no longer works

[asantaga]

Sample in the code no longer works, also affects the wiserHA components

`import draytonwiser
manager = draytonwiser.Manager(wiser_hub_ip=HUB_IP_ADDRESS, api_secret=API_SECRET)

devices = manager.get_all_devices()
for device in devices:

print("Type: " + str(type(device)))
print("Room ID: " + str(device.get_room_id()))
print(device.product_type + " ID:[" + str(device.id) + "]")
print("Battery: " + str(device.get_battery_percentage()))

# A measurement object is a related RoomStat or SmartValve. To make it
# easier to iterate the Device class abstracts some of this away for you
# so you don't have to always care if it's a RoomStat or an iTRV or a SmartPlug

if device.has_measurement():
    print("  Temperature: " + str(device.measurement.temperature()))

    if device.product_type == "RoomStat":
        print("  Humidity: " + str(device.measurement.measured_humidity))`

results in
