Understanding VLANS & HA networking + managed switches + Frigate

Hi folks,
I am looking at two new switches and am unsure if I need managed switches to run a HA device VLAN, or if a VLAN is ‘necessary’.

No. VLAN is not needed
firewall rules get same job done with less problems

@darrenismyname

My routers do not support VLAN and I cannot yet afford to upgrade them. I think it is down to the choice in switches.

I took an old PC and installed Opnsense. Best ideal i ever had.
OpenWRT is another option.

also there is this

@Sir_Goodenough

Segmented networks are not officially supported within HA.

HA is designed and expects a flat subnet to work as intended.

Just learn about firewall rules and subnet masks and use them instead of VLANS otherwise you will get nothing but pain.

This is because every segmented network is different for IP’s and number of segments and firewalls and sharing rules and about 650495849085 other things.
This does not mean you can’t use them or that they can’t be made to work, it means that to get them working you are the support structure on your own subnet(s). Consider it Advanced mode…

For another opinion, there is this: The enterprise smart home syndrome
