+# node-red-contrib-meross 
+
+This provides nodes for locally controlling e.g. Meross Smart Plug (without cloud!). It's requiring a Merross token and a corresponding timestamp to be provided by you. You should get this data via network sniffer or traffic interception between your Meross app and your Smart Plug. node-red-contrib-meross delivers 2 nodes:
+
+## Meross Config
+Meross Config is a config node to set the token and timestamp for being able to locally communicate with your devices.
+
+## Meross Smart Plug
+Meross Smart Plug can be used to set smart plugs state and/or poll its current state. For setting smart plugs state to on|off you simply provide a boolean value (true|false). To request its current state you send any non-boolean payload.
+
+# Currently supported devices
+- Meross Smart Plug MSS210(EU)
+
+# Requesting additional devices
+To be able to implement additional devices feel free to provide sniffed communication between your app and devices.
+You might also feel free to directly contribute in this project.
