TCPLighting

This plugin integrates a ​Connected By TCP LED lighting gateway with a Vera controller. Once a device for the gateway is created, the plugin in turn creates child devices (of type Dimming or SwitchPower, as appropriate) for each connected bulb. Since the bulbs are created as standard devices, they are available for control via scenes, mobile apps, etc.

Pre-Installation

Set up your Connected By TCP LED gateway and bulbs as per the instructions provided with the devices. Ensure that everything is working (i.e. lights can be controlled using the smartphone apps or gateway web interface) prior to installing the plugin.

Installation (UI5)

1. Download and unzip the attached zip file.

2. Upload all of the plugin XML, JSON and LUA files using the Apps / Develop Apps / Luup files page. Make sure to click the Restart Luup after upload checkbox.

3. Wait for the Luup restart to complete.

4. Once the upload and Luup restart are completed, use the Apps / Develop Apps / Create Device page to create a new device for the gateway.
   1. Enter D_TCPLightingGateway1.xml in the Upnp Device Filename field.
   2. To try out the experimental gateway auto-discovery feature, leave the IP field blank. See the notes on Auto-Discovery below.
   3. If you know it, you can also enter the IP of your gateway in the IP field.

5. Wait for the Luup restart to complete.

6. Refresh the Vera UI for good measure.

7. When the gateway device is initialized, it will poll the gateway and create child devices for each bulb. If a bulb's room name matches that of a Vera room, it will be automatically added to the room. Note that the device UI for the bulbs is often partially rendered when first created. A browser refresh normally fixes this.

Auto-Discovery

The Connected By TCP LED gateway supports a subset of the ​Simple Service Discovery Protocol (SSDP) which is part of the ​Universal Plug and Play (UPnP) architecture. In theory, this should allow this plugin to automatically determine the IP address of the gateway without user intervention. However, there are several reasons why this may not work in practice:

1. SSDP uses IP multicasts to search for devices providing UPnP services. Depending on how your Vera and local network are configured, the multicast requests may not reach the gateway. For example, your router may not be configured to forward multicasts from the wired to the wireless segments of your network. This is also discussed in the documentation for ​futzle's ​Wemo Plugin.

2. VeraLite controllers have a slightly odd network interface configuration which results in situations where the multicast responses may not come back on the expected interface. This is described ​here. A workaround is described ​here, but this pretty well defeats the benefits of auto-discovery, given the steps involved.

If auto-discovery doesn't work for you, then you can manually specify an IP address by updating the advanced properties of main TCP Lighting gateway device (click the wrench icon, go to the Advanced tab, and enter the gateway's IP address in the IP field). You may need to check the DHCP client table of your home router to find the IP address of the gateway. Another way of getting the IP address is to open a command window on a PC that is on the same network as the lighting gateway, enter the command ping lighting and note the IP address that the lighting host name resolves to.

v0.3 Release Notes:

• Better handling of unknown room names, i.e room names from the Connected By TCP Gateway that do not match Vera room names. The plugin will now only update the room name if a match is found. Previous versions erroneously set the room number to zero in such a case.

v0.2 Release Notes:

• Includes more robust handling of devices and gateways going offline and coming back online. Device numbers should now be retained so that scenes, etc. are not broken. Polling continues after a failed HTTP request to the gateway.
• Experimental and partial implementation of gateway SSDP auto-discovery.
• Gateway device will now get a default name assigned.
• Bulbs will have manufacturer and model attributes set.
• Logging is a little less verbose.

v0.1 Release Notes:

• This is my first attempt at a Vera plugin, so please do not hesitate to provide constructive criticism.
• This is an unsupported hobbyist project. I am in no way connected with ​TCPi (the makers of the Connected By TCP gateway and bulbs) or ​Vera Control, Ltd. Please do not ask them for support with this plugin.
• Code is based on an undocumented HTTP API.
• Only tested on a Veralite with UI5.
• Only tested with A19 dimmable bulbs.
• Default polling interval is 60 seconds. Therefore, any changes made outside of the Vera environment (using a remote or the Connected By TCP / Greenwave Reality apps) may take up to 60 seconds to be reflected in the Vera UI. Ditto for new bulbs.

To-Do:

• Store code in code.mios.com SVN repository. [Done]
• Gateway auto-discovery via SSDP. [Partial/In Progress]
• Additional gateway and light variables settings. [Done]
• Testing with multiple gateways.
• Energy metering (maybe).
