+This package contains some fake lamps, power_relay, and bots:
     - lamp:         a simple lamp implementation
     - lamp_minimal: a simple lamp using schema devices
     - power_relay:  a power relay 
     - temperature:  a fake temperature sensor
     - autobot:      a bot than send turn_on/off and  set_brightness
+    - asyncbot:     same as autobot with asyncio
+    
 
 To run a module simply call: python -m xaal.dummy.module 
 Example: python -m xaal.dummy.lamp 8e1495cc-b98b-11eb-8432-d6bd5fe18736
