Installing gpsd Alternate Method w/o Enabling IPv6

This is an alternate method to install gpsd daemon on a Raspberry Pi running CoachProxy or eRVin version 0.2 and older. eRVin version 0.3 and newer already has the gpsd daemon installed. This method allows the dependency error to occur during installation, describes a fix, then allows the install to complete. This method was how I originally resolved the problem and is just here for reference. The newer install method fixes the dependency issue (whichLearn More

Adding GPS to your eRVin System

  Adding a GPS Receiver to eRVin Adding a GPS receiver to eRVin is very straightforward, especially for eRVin version 0.3 and newer, all you need do is plug a USB GPS receiver into one of the eRVin USB ports!   So why does eRVin need a GPS? eRVin is an automation system, the more things it knows, like location, the more useful the things it can do. Here are some ideas: Set specific lightsLearn More

Installing an eRVin Software Image

What’s an Image? An eRVin image is a data file that contains all the necessary software for your eRVin hardware allowing it to control your RV, this includes the operating system (OS) as well as all the application and configuration files. The uncompressed size of the image is about 3.5GB, the zipped download is about 1.1GB. This post describes how to download an image and flash it to a micro SD card. The download mightLearn More

Connecting eRVin to your RV

At this point you should have assembled the eRVin hardware then downloaded and flashed the eRVin OS image.┬áThis tutorial assumes you have an existing wifi network aboard your RV, preferably with full time internet access. Connecting eRVin to your RV-C Network Step 1 – connect your eRVin system to the RV-C network on your RV. The easiest and most accessible place to do this is on the front of a Firefly panel. You may haveLearn More

Downloading and Installing eRVin Configuration Files

Now that you have the eRVin hardware built,┬áthe image installed and have it connected to your RV, the first thing you will want to do is download and install the proper configuration for your RV. eRVin OS v0.5 or later adds the ability for you to easily download and install new or updated configuration files via a simple tap or click operation from the eRVin “app” (aka “dashboard”). No complicated computer knowledge needed! A fewLearn More

Accessing Node-Red Flows

Accessing and using Node-Red may be needed to complete many possible tasks to customize eRVin for your RV. Tasks such as configuring Virtual Smart Home Alexa Account integration (eRVinOS v0.6x and above), or customizing the lighting buttons to match the configuration of your specific RV, or updating a particular “flow” with a new version. Don’t worry, it’s a graphical point and click environment and easy to work with. This post describes how to connect toLearn More

Accessing the eRVin Raspberry Pi Desktop

eRVin runs on a Raspberry Pi microcomputer. In some instances it is useful to connect directly to the Raspberry Pi (RPi) to accomplish specific tasks, for instance installing a new program or doing some updates. Sometimes it is just a desire to explore what is happening behind the scenes. If you have no interest in those sort of things this post isn’t for you, otherwise read on for detailed instructions on how to get aLearn More

Add SeeLevel Tank Status to eRVin

Already have a Garnet SeeLevel system aboard your rig? If you are using eRVin it’s a fairly simple matter to add tank level status for the Fresh, Gray and Black tanks to the eRVin dashboard. This requires replacing your current SeeLevel monitor panel with an RV-C version. The existing SeeLevel sensors and wiring remain as is so it’s a fairly straightforward swap. Cost is about $210 all in. The new monitor also comes with aLearn More

Adding Aquahot Control to eRVin

Controlling your Aquahot with eRVin can be fairly easily accomplished with some minor wiring additions using unused channels on your Firefly G5/G6 panel. While some of the photos of the wiring may look complex, don’t let that throw you, this is actually a fairly simple project.
