Cummins EC AGS+

Great concept and works well but it keeps logging me off even when I go back to the app within 30 minutes. There is no way to keep you logged on or Face ID. I have to put my password each time, very annoying.

Update: gateway firmware update (via this app) on April 13th, 2023 appears to have addressed the issue of the auto start changing from a/c activation based on temperature to battery monitoring. In a test run today, I ran the AGS and air conditioner long enough on a hot day for the generator to start. Cool the van by running the a/c, then stop when target temperature was reached, and start again when the temperature rose. The rest of my feedback on this app continues to stand. Cummins took a good step forward, but there’s more to do. —— The auto-start module is sold as a way to keep batteries charged, interior of the RV at a safe temperature, or both. The software in the gateway and that in the app are unreliable. After one cycle of temperature-activation, the gateway then thinks it is supposed to only monitor batteries (even if set to NOT monitor battery voltage) and the RV interior is allowed to overheat. The app constantly asks for passwords and reauthorization rather than simply reconnecting to the generator. It gets tiresome and could so easily be fixed. There is no way to reset the “hours to service” after doing an oil change on the generator, making the maintenance interval reminder completely useless. It’s not just the app that’s flawed, it’s the firmware in the gateway.

THIS PRODUCT IS UNRELIABLE AND UNSAFE FOR PRODUCTION, DO NOT BUY! Onan Cummins is still stuck in the 80’s thinking they are the god of all. Nope. This product is a scam! Look at Victron Cerbo GX. You get real data and control and historical analytics plus true remote/cloud control. This product only reads in 33% increments on the SOC side. Seriously, even your gas gauge is more granular. I hope this product is recalled. It’s created serious safety hazards. It’s auto start turn the generator on even at 100% soc. It is a gamble if you will get accurate reads in the voltage side. Generator hours after numerous factory resets never shows. Maybe 50% of the time after reset you get a voltage reading. It’s sad that the included temp sensor lets you see the battery volts, yet it’s not possibly on the generator house or starter, only very questionable reads at 33% block that never shows accurately to all the other SOC readings outside their crap hardware. Flagship product. Most certainly not. Creating the next titanic, 💯!!! No gold function for remote checking on your system, also absent. The fact they didn’t implement an basic iOT cellular or WiFi option let alone canbus shows how removed from basic industry standard their engineers must be. Can’t wait for the recall and class action. I think I’ll head the start of that.
