The app works well

We used OnCue for the first few years we had our whole house generator. I liked it, but was only able to monitor it from my laptop while traveling (RV). I like that we can both monitor using OnCue Plus from our phones and iPads as well as laptops. We use it to monitor the generator when we are away but rarely (if ever) use it to control the unit. My only issue does not appear to have anything to do with OnCue Plus. Occasionally the generator fails to start and then sets an “Over crank” fault. This fault requires using the keypad on the generator to put it back in AUTO mode. This always seems to happen under extreme weather conditions when we are away from home. such was the case a couple of weeks ago when temperatures where in the minus teens. One of the main reasons we have this generator is to ensure we have power under exactly these kinds of circumstances.

Useful but lacking in several key capabilities

A must-have if you have a Koehler generator but... it’s lacking several key capabilities that would make it so much more useful.

1. You cannot set the controller time from OnCue. You have to get the key and go to the generator.

2. You cannot set or reset the exercise time from OnCue. You have to get the key and go to the generator. If you remotely start the generator, that becomes the new exercise start time and resets the exercise interval.

3. You cannot see the output current of the generator.

4. You cannot read the engine oil pressure. At least on the 20RESA - just the oil temperature and the temperature is not even close to accurate.

5. It randomly looses the network connection and will not always reconnect without a hardware reset which requires removing AC power and disconnecting the genset battery. Then it will immediately reconnect but this is a lot of effort and could be fixed in the controller firmware.

I’m a retired electrical engineer with extensive experience in embedded control and software development - I know what I’m talking about here. As I said, it’s a must-have but it could be a lot better.

Embarrassing Technology

Koehler should be embarrassed by how poor their technology is. Being in the tech industry, including User focused cloud applications, its like Kohler doesn’t test their technology. Simple things just don’t work - or don’t work consistently, and you never know if its broken or the service down. Additionally, I’m not sure what industry they hire out of, but their app and technology is incredibly NOT user focused.

Thank goodness this is a nice to have feature and you don’t have to rely on it for anything. If you did, Kohler generators would be going out of business - though I did recently read an article about poor quality control of Kohler generators. Maybe QA of manufacturing and QA of tech report to the same person.

In today’s world, they should simply be embarrassed. Kohler - hire some decent people to your tech team. You’ve had long enough to get this right...and you still haven’t.
