 For this reason our wrapper is still maintained. Even if its documentation is not any better than original library, it still
 provides basic operations in less confusing way.

 ## Supported features
 
-This project is aimed to offer simple facade thus it is limited to following bacnet object types:
+This project is aimed to offer simple facade thus it is limited to device and following bacnet object types:
 
 * analogInput
 * analogOutput
 * analogValue
-* binaryInput (not tested)
+* binaryInput

-* multiStateInput (not tested)
-* multiStateOutput (not tested)
-* multiStateValue (not tested)
+* multiStateInput
+* multiStateOutput
+* multiStateValue
+
+As of 1.2.x there is support for additional object types, however they are considered experimental:
+
+* calendar
+* pulseConverter
+* schedule
+* characterstringValue
+* dateTimeValue
+* largeAnalogValue
+* octetstringValue
+* timeValue
+* integerValue
+* positiveIntegerValue
+* datetimePatternValue
+* timePatternValue
+* datePatternValue
+* accumulator
+
+Most of them is still commendable and supports access through `present value` property, but some of them bring additional properties
+which are not visible through wrapper APIs.
 
 If you are interested in adding other types of objects to API feel free to submit PR.
 
-Each property of type enlisted above can be read and attempted to set via `client.getPropertyValue` and `client.setPropertyValue` method calls. There are two variants of set/get property methods - with and without converter argument. If you know type of property then you can convert it upfront to bacnet4j structure. By default library will try to guess, however in most of cases it will fail.
