It is a little hefty for a homelab-level setup, but the impressive bit to me is that they've kept compatibility with it longer than we've replaced UPSes at work (it looks like the RMCARD205 and 305 were introduced in 2018), so instead of paying for that hardware built into each unit, the RMCARD has been a one-time purchase we can bring from unit to unit.

APC UPSes that support their network management card add in - then the cards can frequently be purchased on eBay for $30-$100, you have to make sure the UPS supports the card, but they are excellent. Model numbers like ap9631 (if i recall). I run about 10 of them across different locations and they work great , some of them for 8+ years now. ( about a year ago when I got a new ups, Apc still offered the older firmware for download, however after a certain FW version it started going to a cloud subscription model - so be sure to keep the old firmware. If you’re worried about the firm or not being updated on the non-cloud version, just be sure to vlan/firewall control access to them which you should be doing anyway)
