After troubleshooting for months now I hope the community can help me. I have home assistant running satisfactory except once every couple of weeks. Usually during the night it looks to me that some kind of DHCP server in home assistant takes over. It ruins my whole network including the wired connections. The only way to reset it is disconnecting and rebooting home assistant. Obviously I can not read the log file after that so I have no idea what caused it.
I am using a nightgear nighthawk R9000 with firmware v1.0.5.38. Behind that is a Orbi system (one main, two sattelites) configured as bridge with DHCP off ofcourse.
Sorry for using that language, but not being native English caused it I think. Not trying to offend anybody but trying to describe my problem in one title!
It looks like 90% of the devices are “taken over” when that happens. One of the wired devices out of 9 stays online (a camerea where I have 5 of the same camera’s). It looks like they get their IP adresses from some kind of DHCP server starting with different numbers than I have configured my network. When I disconnect HA from the network and reset the router (Nightgear Nighthawk) everything comes back online again.
I understand the information is limited. If I was able to look at the Log file I would have lots of information and figured it out by now I guess. As stated it happens only once every couple of weeks and usually during th night. I have not caught it happening “in the act” yet.
I use a variaty of integrations. TuyaV2, Shelly, ewelink, Mosquito MQTT, Bose none of which I can think off will take over my DHCP server… I do not use Pihole
Is it possible that these compete for dhcp somehow?
I would do new install and resetup if I truly believed HA was cause. It is unlikely but if it was cause I’d expect any attempt to restore backup would have same result and new install was only option. Again, HA Not do dhcp but some addon can.
