In the on-going battle between the fun of the homelab and trying to save some money, I've been looking at energy usage more. So I put a smart outlet between the wall and the UPS that holds most of my equipment. I'm seeing faily consistent average of 240W, which ends up being about 15-20% of my total house usage each month. Here is what is all there:
- Juniper EX330P: Powering:
- 4 TP-Link EAP245 APs
- 2 Amcrest IP5M-T1179EW-28MM IP Cameras
- One of those mini, 4 2.5GBe port, no-name PCs (Celeron N5105) running firewall/router
- 2 HP EliteDesk 800 GS Mini (i5-6600 using NVMe drive) - Running Proxmox
- Dell OptiPlex 7050 Micro (I5-6600T using NVMe drive) - Running Windows
- HP Pavilion P6520y (AMD Athlon II 625, PS replaced with Thermaltake Smart 430W) - Running TrueNAS
So I assume the old HP Pavilion machine and the Juniper switch are my two main contributers. I shut down the HP and power dropped to about 160W. Can't really shut off the Juniper as it will take all the sensors with it.
My questions are:
- Would I really gain enough to outweigh the build costs, by rebuilding the TrueNas machine with something newer like one of the builds here (https://nascompares.com/guide/recommended-jonsbo-n3-nas-builds-for-300-500-1000/)
- Is there something <$150 to replace the Juniper that would still give me PoE, VLAN, and SFP+ ports? Or is the gain there, also not really going to balance out?
