Having issues since the newest version of the app was released.

Ever since the latest version app was released. Having several issues monitoring one of the multiple generators on the app. Also finding it impossible to find settings for that individual generator as far as notifications settings. I monitor many customers generators as a dealer for Kohler. Im sure as a great company this will be resolved sooner than later. Also I have notice the online version on Google chrome is identical and has the same bug of not allowing you to go back to the main page after viewing notifications. I have to log out and back in to get back to main screen. Both the I phone app and Chrome do the same thing. Furthermore I cannot get to the link via Microsoft Edge or Internet explorer anymore. They both are showing errors with credentials. Saying the connection isn’t private. NET::ERR_CERT_REVOKED. Be happy to update my review to 5 stars when resolved. Thanks.


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.
