==== E+E Temperature & Humidity driver ====

=== Description ===

This driver is design to allow communication with E+E Elektronik's EE210 humidity sensor, via the ezeio MkII's Modbus serial port. The driver may be compatible with other E+E humidity sensors with Modbus connectivity, such as EE072, EE150, and EE211.

==== Settings (center panel) ====

**Name** - The name is up to the user. Our suggestion is to choose a naming convention that makes the viewing the device list intuitive. Such as referring to the sensor and/or application. Keep the name short as it will be combined with the register name to create the default "Field" name (if added to "Fields")

**Active Check box** - Check this box and "Save changes" to run the driver. The driver program can be suspended by unchecking the box and clicking on "Save changes". 

**User Notes** - This space can be used to store information specific to the device and your application, such as: location, wiring, scaling, etc.

**eze System Notes** - In this space we provide: wiring instructions, product image, product details. 

 ----

**Modbus Address** - Enter the devices unique Modbus address (device ID)

**Device model Units** - Select "Metric" or "Imperial" as your preferred units of measure.

==== Status & Registers (right panel) ====


=== Device Status ===

**Driver info** - Typically this is the name from the program file

**Driver updated/version** - Date loaded or updated and the version of the driver

**Battery & Signal** - Signal indicates the progress through the script. If driver fails to operate, signal number indicates progress 

**Driver status** - Color and text of status bubbles give a quick visual reference of Communication, Operation, and Application

**Communication** - Com count indicates number of successful and unsuccessful data packets received
