This is correct.
I wired mine as well and it is a “straight”. Confirmed with a cable tester.
My wired connection is connected to a ASUS mesh node that is also hardwired to my main router. The port is a 1gbps port.
I tried the first test of this. I disconnected the modem for 5 minutes. After reconnecting (5:45 total) no issue. I’ll try and get more tests over the next couple of days.
Thanks and apologies as I was confused about your topology. Here’s a picture of what I think you have.
You have disconnected #2 and connection recovered
Restarting the comcast modem caused the connection to not recover
We should try if not already done, unplugging 3/4 and 5/6
I have done 1- 2, 3-4, and 7. I was going to try 7 for 11 minutes next. Can do different if you think it would give useful data?
I would think 7 and 5 -6 would be the same? Not sure as I never studied networking in my engineering degree and don’t know if the router reacts differently from a cable disconnect vs a modem losing connection to the internet. I know my main router shows an internet disconnect (red led) with either cable removed.
Sounds good. Current state is all those tests worked - meaning it reconnects - and the only failure is when the comcast modem is reset?
One of the nuances is this. If for example, if cable 5-6 is disconnected. The routers hardware should immediately notice the loss of media AND it should remove Comcast’s Gateway from its routing table. If the generator then sends a packet to kohler cloud, the router won’t have a route for it and will return a TCP error to the generator,
In contrast, if we put a Ethernet hub in the middle of 5-6 and disconnected the cable from the hub to the modem; the router would still have media since it’s connected to the hub. If the generator then sends a packet to kohler cloud, the router will send it out the wire to the hub (and it goes nowhere), and then eventually the generator will timeout (or crash 
) when no response is received. By default TCP stacks have a 15 minute timeout. Of course most apps change this to a more realistic number like 30 seconds.
I’m going to run some tests on my generator this week. When it fails, what do you do to reboot it?
No failures in my tests(yet). Are you saying to disconnect for 15 minutes next?
The easiest way is to reflash the firmware. No power removal is necessary. Connection is the mini USB (old style) on the board. There is a rubber covering over it. Software utility and firmware is on the Kohler website. If you can’t find it, let me know and I’ll send you a link. Sometimes I have had to flash it a couple of times. You will know if you need this if the display does not come back on and the two LEDs are flashing. According to Kohler the board is stuck during boot and a reflash fixes it. Once back on you need to reset the time and schedule for test. Network setting remain. Who would have thought?
The other way is remove power from the PCB. Kohler recommends disconnecting the battery and the power to the generator. Much easier to remove the two screws from the board and then the connectors on the back. I believe you only need to remove the power connector but I have removed all three.
Wow, that’s nuts. Does the generator work when it’s in this state (meaning provide power)?
No it does not. It never took more than twice.
I had several internet outages last week. Longest one was 90 minutes. The generator reconnected every time.
We have had cold weather recently so I have not tested further. Interesting that you lost connection for 90 minutes and it reconnected. Never heard back from Kohler support.
Just had Comcast go down last night for about 35 minutes. No issue with the generator. Maybe it is fixed? I’ll let you know if I lose it again.
Thanks.
I just got two emails from Kohler indicating they lost comms with the generator and that is was restored. Never seen these before. So it seems like they have made some changes on the cloud side.
Just lost connection today. Does not look like Comcast went down as not issues from anything else. I can still ping the generator, but it lost connection to the Kohler website. Looks like another reset!
The oncue integration on my system lost connection at 10:50:01 ET and resumed at 11:06:01. How does this compare with the time of your issue?
I see a gap in the HASS data during this time, but the data did resume and seems current as of now.
I see no disconnect in the Ping sensor.
Yeah, I think they had an outage today. I got the same lost connection, and I’ve never had one before.
Oncue sent me a message at around 7AM EST that it lost communication with my generator. I had noticed this earlier but now it is working again. First time that it came back without a reset.
Ping was never lost unlike earlier occurrences.
Is this in Home Assistant or from something else?
