# TiVo Binding

This binding controls a TiVo (opens new window) Digital Video Recorder (DVR) that supports the TiVo TCP Control Protocol v1.1 (see TiVo_TCP_Network_Remote_Control_Protocol.pdf).

# Supported Things

Most TiVo DVRs that support network remote control can be managed/supported by this binding. Please note that beyond sending a full set of control commands, the network control protocol is very limited. The only feedback provided is the currently tuned channel number and whether or not the channel is recording.

It is possible to control a TiVo at a deeper level through an authenticated API. See the kmttg project for more details. There are no current plans to add any of the authenticated API features to this binding.

All TiVo devices must:

Be connected to a local area TCP/IP network that can be reached by the openHAB instance (this is not the WAN network interface used by cable service providers on some TiVos to provide the TV signals).
Have the Network Remote Control function enabled to support discovery and control of the device. This setting can be found using the remote control at:
- TiVo branded boxes - using the remote go to TiVo Central > Messages & Settings > Settings > Remote, CableCARD & Devices > Network Remote Control. Choose Enabled, press Select.
- Virgin Media branded boxes - using the remote select Home > Help and Settings > Settings > Devices > Network Remote Control. Select the option Allow network based remote controls.

# Discovery

TiVo devices with the network remote control interface enabled will be displayed automatically within the Inbox.

# Binding Configuration

There are no overall binding configuration settings that need to be set. All settings are through thing configuration parameters.

# Thing Configuration

The thing has the following configuration parameters:

Parameter	Display Name	Description
host	Address	The IP address or hostname of your TiVo DVR.
tcpPort	TCP Port	The TCP port number used to connect to the TiVo. Default: 31339
numRetry	Connection Retries	The number of times to attempt reconnection to the TiVo DVR, if there is a connection failure. Default: 5
keepConActive	Keep Connection Open	Keep connection to the TiVo open. Recommended for monitoring the TiVo for changes in TV channels. Disable if other applications that use the Remote Control Protocol port will also be used e.g. mobile phone remote control applications. Default: True (Enabled)
pollForChanges	Poll for Channel Changes	Check TiVo for channel changes. Enable if openHAB and a physical remote control (or other services use the Remote Control Protocol) will be used. Default: True (Enabled)
pollInterval	Polling Interval (Seconds)	Number of seconds between polling jobs to update status information from the TiVo. Default: 10
cmdWaitInterval	Command Wait Interval (Milliseconds)	Period to wait after a command is sent to the TiVo in milliseconds, before checking that the command has completed. Default: 200

Some notes:

If openHAB is the only device or application that you have that makes use of the Network Remote Control functions of your TiVo, enable the Keep Connection Open option. This will connect and lock the port in-use preventing any other device from connecting it. If you use some other application, disable this option. Performance is improved if the connection is kept open.
Poll for Channel Changes only needs to be enabled if you also plan to use the TiVo remote control or other application to change channel. If openHAB is your only method of control, you can disable this option. Turning polling off, minimizes the periodic polling overhead on your hardware.

# Channels

All devices support the following channels:

Channel Type ID	Item Type	Display Name	Description
channelSet	Number (1-9999)	Current Channel - Request (SETCH)	Displays the current channel number. When changed, tunes the DVR to the specified channel (unless a recording is in progress on all available tuners). The TiVo must be in Live TV mode for this command to work.
channelForce	Number (1-9999)	Current Channel - Forced (FORCECH)	Displays the current channel number. When changed, tunes the DVR to the specified channel, cancelling any recordings in progress if necessary i.e. when all tuners are already in use / recording. The TiVo must be in Live TV mode for this command to work.
menuTeleport	String	Change Special/Menu Screen (TELEPORT)	Change to one of the following TiVo menu screens: TIVO (Home), LIVETV, GUIDE, NOWPLAYING (My Shows), SEARCH, NETFLIX.
irCommand	String	Remote Control Button (IRCOMMAND)	Send a simulated button push from the remote control to the TiVo. See below for available IR COMMANDS.
kbdCommand	String	Keyboard Command (KEYBOARD)	Sends a code corresponding to a keyboard key press to the TiVo e.g. A-Z. See Appendix A in document TCP Remote Protocol 1.1 for supported characters and special character codes.
dvrStatus	String	TiVo Status	Action return code / channel information returned by the TiVo.

To change channels simply post/send the number of the channel to channelSet or channelForce. For OTA channels, a decimal for the sub-channel must be specified (ie: 2.1), for all others just send the channel as a whole number (ie: 100).
Keyboard commands must currently be issued one character at a time to the item (this is how the TiVo natively supports this command).
To send multiple copies of the same keyboard command, append an asterisk with the number of repeats required e.g. NUM2*4 would send the number 2 four times. This is useful for performing searches where the number characters can only be accessed by pressing the keys multiple times in rapid succession i.e. each key press cycles through characters A, B, C, 2.
Special characters must also be changed to the appropriate command e.g. the comma symbol(,) must not be sent it should be replaced by 'COMMA'.

The item TiVo_SetChannelName depends upon a valid tivo.map file to translate channel numbers to channel names. The openHAB MAP transformation service must also be installed.
See [this discussion thread] (https://community.openhab.org/t/bogob-big-ol-grid-o-buttons-is-this-even-possible-yes-yes-it-is/115343 (opens new window)) for an example of setting up an advanced UI to simulate the look of the TiVo remote.

This example does not use the 'Current Channel - Forced (FORCECH)' channel. This method will interrupt your recordings in progress when all your tuners are busy, so it is omitted for safety's sake.

tivo.rules:

This rule was used to overcome limitations within the HABpanel user interface at the moment when using transform/map functionality.
The following rule shows how a string change to the item TiVo_KeyboardStr is split into individual characters and sent to the TiVo. The method to send a keystroke multiple times is used to simulate rapid keystrokes required to achieve number based searched.
A simple custom template widget can be used within the HABpanel user interface for tablet-based searches. See [this discussion thread] (https://community.openhab.org/t/tivo-1-1-protocol-new-binding-contribution/5572/21?u=andymb (opens new window)).

when
  Item TiVo_Search received command
then

then
    if (TiVo_KeyboardStr.state != NULL && TiVo_KeyboardStr.state.toString.length > 0) {

        // Command to get us to the TiVo search menu
        sendCommand(TiVo_MenuScreen, "SEARCH")
