Shopping advice: 48 port non-poe switch with good/great HA support

Hardware

Hi all,

I’m looking for some shopping advice … I need a bigger switch for my home and want to upgrade from my Zyxel 24 to 48 ports.

One feature I would really like to have is control how many devices are attached to 1 of the ports. This is quite usually possible with smart managed switches and I have that in my zyxel at the moment as well.

I would also like to monitor if a port goes down/up. I was hoping to do this with Home Assistant so I would not have to dive into SNMP monitoring, which might even require an additional device. I know I could in theory do this with HA as well, but … This is really a deep dive into SNMP …

Any idea what to look for? Zyxel, dlink, tp link, netgear, hp? Anybody done this before?

I would probably go for SNMP instead of hoping that a device has HA support.
It’s not that hard to set up a few SNMP sensors.
I think it will be easier to find good information about what switches has good SNMP support than HA support, especially 48 port.
Not hat many need 48 ports home, and not that many has HA at work. So this is a very niche area.

I’m very happy with my ZyXEL switches, although 10 ports is the biggest I have (GS1900-10HP).

I actually have a zyxel 24 port, but SNMP is really slow on the updating process. It just took 8min until it recognized that a device was disconnected :thinking:

TP-Link Omada switches have an open API and there is a HACS integration that might (might!) provide the additional port status you’re looking for (over the built-in integration, which only has minimal info). Unfortunately a 48 port SDN-managed switch is around $400. For comparison, you can get a used Cisco 2960-48 for around $120 which supports SNMP and in my experience updates pretty quickly, but I don’t know how much detail you will get about connected clients, just port up/down and bits in/out.

PS - if I were using SNMP for status I would consider a tool like this snmp2mqtt which supports HA autodiscovery so you not only don’t have to manually create dozens of sensors, but they would all get grouped into their parent device(s).
