RVC-Proxy ========= A collection of code to communicate with [RV-C devices](https://en.wikipedia.org/wiki/RV-C) on a [CAN bus](https://en.wikipedia.org/wiki/CAN_bus) network. For more information on the RV-C protocol, please visit [www.rv-c.com](http://www.rv-c.com/). Download the complete [RV-C specification](http://www.rv-c.com/?q=node/75) for details on the commands and their parameters. This PDF file is critical for understanding how to communicate with RV-C devices. Prerequisites ------------- * A computer with a canbus network card configured on interface `can0`. * An [MQTT](http://mqtt.org/) message broker. We recommend the [Mosquitto](https://mosquitto.org/) message broker. Programs -------- Our RV-C programs are being added individually after reviewing each. More will be added over the next few weeks. ### rvc_monitor.pl Listens for RV-C messages on a canbus network, decodes them, and publishes summary information to an MQTT message broker on the local host. Most decoders (e.g. DC_DIMMER_STATUS_3) publish to MQTT and print to STDOUT an ordered, comma-separated list of values. Newer decoders return a JSON object containing key-value pairs to eliminate the requirement to know the order of returned values.

This is typically used to control lights, but can also be used to turn other items on and off, such as a water pump or fan. ### ceiling_fan.pl Sends a combination of `DC_DIMMER_COMMAND_2` messages (`1FEDB`) to control the bedroom ceiling fan. ### vent_fan.pl Sends `DC_DIMMER_COMMAND_2` messages (`1FEDB`) to the CAN bus to control the ceiling vent lids and fans in Tiffin motorhomes. Turning fans on and off is handled via a single command, just like turning a light on or off. Opening and closing a vent lid requires a pair of reversing commands with a duration value. For example, to open the galley vent lid on a 2018 Tiffin, the following sequence is sent: ``` Instance 27 Brightness 0 Command Off Duration 0 Instance 26 Brightness 100% Command On Duration 20s ``` To close the galley vent lid, the following sequence is sent: ``` Instance 26 Brightness 0 Command Off Duration 0 Instance 27 Brightness 100% Command On Duration 20s ```
