Hello,
So recently I had some issues changing my IP address from a static one to DHCP (as I was hoping that I could assign the device a 'static' address from my router). However, I feel like the issue I have now is one that I can't resolve myself (which is why I emailed support with no response other than the canned one).
From the hubitat's web portal, I changed static IP assignment to DHCP, expecting that my router would be able to assign it a new address the address range I specified from my router's admin page. After waiting awhile for my hubitat to reboot, I looked over my router's page for new devices that it gave an IP to. After waiting (say) 10 minutes, I unplugged my hubitat from the router and power and tried again. This didn't change anything to which I tried another dummy router I had laying around which also didn't give it an IP. I also tried connecting to the old IP address to no avail.
I eventually tried connecting the hubitat to my computer to do more troubleshooting after giving my computer's ethernet interface a static IP address and having Wireshark listen to it. I also set up a DHCP server on the computer to see if that would give it an IP for some reason when the routers did not. I would have thought that the hubitat would have broadcasted something to the computer's interface, but the only thing Wireshark picked up were messages my computer was broadcasting, not the hubitat.
Out of other options that I could exercise myself, I used an ARP scanning tool to scan a number of IP ranges that the hubitat could have obtained, including the 168.254.0.0/16 range as well as most in the private sector (I wasn't going to wait for all the addresses on 10.0.0.0/8 to scan; I doubted this was going to solve anything at this point anyway). This didn't give any useful results either.
After reading some community posts here, I'm wondering if at some point something on the hubitat was corrupted, but I don't know if I can do anything personally to fix it. I can't talk to the hubitat, so I can't exactly factory reset it, and I don't know if that would be something that I would want to do anyway. Side note there are (were?) only two devices connected to the hubitat, so it's not like I have some elaborate home automation setup that I would loose otherwise.
The hubitat model I have (according to the sticker on the bottom) is the Hubitat Elevation Hub Model C-7. The MAC address is also printed on the bottom, but that didn't seem too helpful other than a way to confirm it was, in fact, the hubitat that was talking if I could actually get an IP address out of the thing.
Any help would be appreciated.
