Best Way to Monitor Your RV House Battery Over WiFi

Question

Question:

I have a 2021 Winnebago Travato. I would like a Battery Monitor for my house battery that will send me a message via WiFi if the Voltage s below a certain level. I cant find any WiFi Monitors on your web site. Do you sell them? Thanks, Tim

Welcome back Timothy,

You're right that you won't see any standalone WiFi battery monitors on our site. All of the battery monitors we carry use Bluetooth, so they're meant for checking your battery when you're close to your RV. If you want to keep an eye on it from anywhere and get it online, the best way to do that is with a Victron SmartShunt, part # VN92ZR, paired with the Victron Cerbo GX, part # VN23VR.

The SmartShunt does the actual battery monitoring, and the Cerbo GX is what connects everything to your WiFi so you can check your battery from your phone, tablet, or computer through Victron's free VRM app.

I think that's going to be the closest match to what you're looking for, and it's a really solid setup if you like being able to check on your RV even when you're away from it. One thing I did want to ask is whether your Travato has a reliable WiFi connection whenever it's parked?

Out of curiosity, do you usually leave your Travato plugged in while it's stored, or are you keeping an eye on the batteries when it's sitting off grid?

Hi, My Use Case is that my Travato is my daily driver parked in my driveway with plenty of sun, and not plugged in. In the summer, I usually keep the Refrigerator on. However if there is a heat wave, I don't leave my house. We had a heat wave of five days, and my house Battery got down to 11.8V. The Batteries are only a year old. It would have been nice if I had an alert when that happens, so I can drive it and charge the battery. I do have good WiFi in my driveway. One other solution, mentioned is that some GPS Monitors also monitor the Battery. I haven't got confirmation of which ones. Thanks, Tim Walker

I totally get it. I had to laugh because we've been dealing with the same kind of heat here in Missouri. When it's that hot outside, the last thing you want to do is go for a drive just to charge your batteries. I did some digging on the GPS trackers too. I wasn't able to find one that can monitor external batteries. The ones we carry, including the PingMaster models, only report the status of their own internal battery, not your RV's house battery. Since you have reliable WiFi in your driveway, I really think the Victron setup is going to be your best bet. I also checked the SmartShunt documentation, and it does support low battery alerts through the Victron app, so it should do exactly what you're looking for by letting you know before your batteries get run down. I think that setup would give you a lot more peace of mind, especially during those stretches when it's just too hot to want to leave the house.
