Welcome to the EDS One Wire Server Plugin for Vera

Discussion here: ​http://forum.micasaverde.com/index.php?topic=8381.0

Overview of OW-Server

The plugin implements an interface for the Embedded Data Systems OW-Server (see ​http://www.embeddeddatasystems.com/OW-SERVER--1-Wire-to-Ethernet-Server_p_152.htm). This is a low cost Ethernet to One-Wire system interface that can be used to interface to a number of environmental sensors. The OW-Server supports a line of advanced environmental sensors from EDS such as temperature, humidity, pressure, light, but also low cost Dallas sensors such as the DS18B20 temperature sensor. The OW-Server supports up to 24 physical devices, although many devices support multiple sensors - in this case, the plugin will provide an individual child device for each sensor.

Installation

Usage

Once the plugin is installed, it will show the number of devices detected on the one-wire bus. You can then click on the properties box, and you will be presented with a tab called "Add Devices". If there are any devices that have not been added as Vera devices, they will be listed here. It's worth understanding how this (currently!) works. In the case of the EDS-ENV range of environmental sensors, many sensors are available on a single device (e.g. temperature, pressure, humidity, dewpoint, and a control relay). You will be presented with a list of the possible devices, and you can select how you want these mapped into Vera devices. It's also possible to select "Ignore", in which case no device will be created. It's important to understand that (currently) once any sensors have been added to Vera from a physical on-wire device, they will not be listed in this window again. So - make sure you add all the variables you want at the beginning!

Once you've selected all the sensors you want added, click the "Add" button and the sensors will be created. It will take some time before the data is actually updated within the Vera device, this is because the plugin performs some averaging to limit the amount of noise on the data. Sensors are typically provided with a single decimal place output (e.g. 15.2 degC, or 45.1% humidity), so this is done to avoid unnecessary data fluctuations.

A Note About Sensors

EDS OW-ENV Sensors: LED and Relay Use

Both the LED and Relays inside the EDS OW-ENV sensors can be configured to provide a binary switch interface within Vera. For this to work correctly, you need to use the OW-Server web interface to set the LEDFunction or RelayFunction variables to value 2. This allows them to be controlled externally.
