So how is a person suppose to operate/manage a FLIC HUB without a mobile device?

Well I think my initial suspicion was correct. Yesterday, 01/28/2021, I had a visit from my ISP's threat prevention group, and a law enforcement officer who asked that he/she rather not disclose which agency they were with at this time. What ever. Since I personally know both people from the ISP, and the fact one of them is married to my cousin I was not concerned about it being a scam.
They informed me they had tracked and were monitoring suspicious traffic coming from my residential gateway. Specifically they were looking for a device that was active in a botnet currently under federal investigation.
I was asked if they could monitor my local network to further identify the actual device that was appeared to be using a fake MAC address. They showed me the MAC address 9A-AF-B1-1A-08-A7. Hmmm? That's the MAC of my FLIC Hub. I handed it over to them to use gather additional surveillance.
Will I get the device back? Maybe? Probably not, but I really don't care. I still hadn't got it to work. Now I know why.

Interesting thing I could not find a OUI/OID registry for 9A-AF-B1. I tried 15 different resources including CISCO Systems, Fluke Int'l, and the standards-oui.ieee.org websites. No listing. Not even when searching by company name.

Now I have to sift through roughly six weeks of internet logs to see if there was any malicious traffic other than just the botnet.
I can hear my father's word ringing in my ears right now, "Well son, are those modern inconveniences really worth it?"

@Emil Well I finally got back to playing around with the FLICHUB again. I have configured the hub to use wifi instead; however, before that I configured the access point nearest the FLICHUB with a new virtual SSID that has both Network and Access Point isolation enabled. Then all DNS traffic for that network is force redirected to OpenDNS preventing access to all known malware and botnet command & control servers. I think that fairly well sandboxes the FLICHUB to a point where I really do not care what the hub does other than send out traffic to other services such as IFTTT.

@Emil, Well no, that behavior has now proven to be nothing more than an annoyance, since a new problem has developed when my Ubiquiti Security Gateway received a firmware update today. Now the SG keeps flagging the flichub as infected with malware and denies all access to the flichub.

I disconnected the flichub from my network. Besides I have not found a way to integrate my Tuya/SmartLife compatible wifi smart plugs with the FLIC2 buttons yet.

I'll revisit this problem after the holiday.

I recently purchased a FLICHUB LR. It is hooked to my network via ethernet since the FLICHUB does not support WPA3. It has a static IP address assigned with a DHCP lease time of 1440 minutes (24 hrs).

For that past couple of weeks I have found the flichub is sending a DHCPREQUEST roughly every 62-67 seconds.
Shortly after 12am the interval is every 62 seconds. At some point that interval increases usually by one second until it reaches 67 seconds 2-3 hours before 11:59pm. I tried power cycling the HUB multiple times with no change. I have tried resetting it to default four times then reconfigure it, but it still does not change.

How do I make the flichub stop this behavior?
