RV Whisper Software Version 4.727 Available

As of May 26, RV Whisper software Version 4.727 is available for customers to upgrade to. This is the software that runs on your RV Whisper Monitor Station (RVM1 or RVM2) that is installed in your RV.

Software Update Instructions

This version includes major performance improvements, especially for customers with lots of historical data and lots of sensors.  It includes the new EasyStart integration, the updated Thornwave PowerMon X integration, and improved WiFi setup reliability.

Numerous bug fixes and the latest security updates are part of this version also.

Thornwave DCPM PowerMon X Firmware Support

If you are using a Thornwave PowerMon (DCPM) sensor to monitor your batteries in RV Whisper, you may need to update your RV Whisper software if you are using the new “PowerMon X” version of the phone app from Thornwave Labs.

Technical Background:

Earlier this year, Thornwave Labs, the manufacturer of the PowerMon battery monitor released a new version of their phone app that is called “PowerMon X”.   If you are using the PowerMon X version of the phone app, that means the firmware running on the PowerMon device is running “PowerMon X Firmware”.

In February, 2022 RV Whisper worked with Thornwave Labs to add support for the new “PowerMon X” firmware by RV Whisper.

This applies to both the “PowerMon 5S” that includes a 500 Amp battery shunt, as well as the classic PowerMon that can connect to an external shunt.
