Some of you may remember my post on the Boat Command remote monitoring system. It lets us monitor things like battery voltages and shore power while we are away and sends alerts should something go amiss. It’s nice to be able to track the battery voltages or get alerted to an intruder when our boat is shrink wrapped for the winter back in RI, but we are somewhere warm and sunny.
Well we also have a similar device on our motorhome, called RV Command. Actually, the hardware is identical to the Boat Command, but the nomenclature is changed to reflect RV functions. For example the Bilge Pump run time tracking is renamed to Engine Hours. The RV Command is the same price as the Boat Command (currently $299) and ongoing cellular based (AT&T) communications service is still $8.99/month.
When wired as described below the RV-Command will monitor and alert us via text and/or email for all of the following conditions:
- House Battery Voltage (configurable low voltage alert)
- Start Battery Voltage (configurable low voltage alert)
- Generator Engine Hours
- Shore Power (alert sent when disconnected)
- Temperature Inside via Sensor (configurable HIGH & LOW temp alerts)
- Temperature Outside (from web based data)
- GPS location with GeoFence (configurable alert radius)
Since I have already done a previous review, this post will provide details regarding exactly how the RV-Command was installed in our 2017 Entegra Aspire motorhome. The Onan generator and control module equipment is the key to making this an easy install and this gear is very common on all types of RV’s, so this information is likely to have a much larger audience than just Entegra owners.
Basically, it was a really simple install. Our Entegra has a 10KW generator made by Onan and it is controlled by a remote panel called the EC-30. The EC-30 provides generator control, status monitoring, error reporting, auto start configuration, etc. It just so happens that all of the most important signals needed by the RV Command are present in the EC-30 wiring harness.
The location of the EC-30 on our coach is in a wiring compartment over the entry door. Turns out this is also a good place to put the RV Command because it has good access to cellular radio signals and it’s built in GPS chip can see the sky.
The hookup was straightforward connecting the RV Command sense wires into the appropriate EC-30 signal wires. The diagram below provides the details.
