Starting a new thread as this was getting lost in the Hints, Tips & Troubleshooting thread.
Post details of your integration with Home Assistant etc.
Ohh thats a neat little box!
Are you sure on power consumption? Looking at specs some are 90 watts?
Pretty sure. 😉
Power above is measured using a Kasa KP-115. The T series CPUs are pretty efficient at low CPU, with the ability to burst when more horsepower is needed.
EDIT: it's also running a Coral TPU, Sonoff ZigBee dongle and a Bluetooth dongle.
Likely a 90W power supply, But general "idle" consumption i can see it being in the 10-20w range (of actual use)
Thanks.. I'm looking at a optiplex 7090 micro. Should be similar?
I have a similar device.
Is there a step by step guide to set up home assistant.
I made a balls of it last year and gave up.
Is it a T series CPU? Should be similar.
If you're looking at that one on adverts for €330, I'd suggest that is overkill for what you need... Unless you want to run something like Proxmox and run multiple different VMs on it.
Going from a RPi to an old Optiplex Micro is going to be like going from a Lada to a Rolls Royce.
It's that spec but not that price from a friend who's selling one
Have a look at this and come back to us if you get stuck.
How easy is it to image the Rpi and restore to the Optiplex 7060?
Did you go the Proxmox route?
Also @Jonathan do you have a UPS for your setup?
Full backup the the home assistant on the RPI from home assistant, Download
Install HA on the new server(whaterver way, Proxmox, Kvm, bare metal) and restore the backup.
No. Vanilla Debian install and run HAOS in a VM on top of KVM. Went that way because it gave me more options, but tbh, if I was starting over, I'd probably just use Proxmox (which is Debian under the hood anyway).
No UPS (joys of a very stable urban grid supply). 😋
I'm running the same type of thing - a Lenovo M73, like this

Those are animal. I use a 7040 here as a desktop. Fitted with an NVMe and then an additional SSD too. Running HA in Docker and also using Portainer and Shinobi CCTV. I'll share my docker-compose.yml if it helps. With a reasonable backup of the home_assistant folder, I had a restored instance up and running in 25 mins after a crash (lightening induced, blew the motherboard) recently.
I'm looking for some help with a Shelly pro 3 em. It's an energy monitor with 3 clamps.
The electrician installed the device in my fuse board but when I connect to it, 2 of the clamps are returning 0 watts. The em is for 3 phase but can be used for single phase. I assume that I need to setup the device to tell it to monitor single phase but I can't find any instructions to do so.
Has anyone gone through this before and offer some guidance on it? Thanks
Hi! Are you using it with Home Assistant or how do you plan on collecting/aggregating the data? A screen-shot of the landing page on the Shelly might help here, but as I understand it If it's a three-phase EM and only one of the CT clamps was installed then you only need to look at the current and voltage for that one clamp, ignore the remainder on 0W.
I will be using HA eventually but at the moment I am just trying to get the clamps to read anything.
When I connect directly to the EM attached is what I see. The third clamp has data, the first 2 has nothing. I think I'll have to ask the sparks to come back as maybe it's loosely wired or something l. I can't see any setting is the Shelly that I am suppose to setup
But what are the first and second clamps attached around, nothing or other circuits?
First is around mains, second is around solar
Ok up and running with the Dell 7090 micro. Installed proxmox and ha and restored and flying it. Power consumption seems to be hovering around 5 watts which is perfect. So I'm not a proxmox expert. I followed this guide.
I'd two issues. Machine disk was set to raid configuration so proxmox couldn't find the disk during the installation. Changed the settings in the bios and all good. The other was the script to install ha had a version number in it. Changed that and worked fine.
Couple of questions...with proxmox can I do a backup of the machine easy enough? I feel like I might have opened up another potential rabbit hole.. ha does seem to be a lot zippier
Welcome to the club.🥳
You can snap the HA VM through proxmox but you're as well off using the HAOS backup for day to day backups. Take a proxmox snap if you're doing any major upgrades or risky changes and you can roll back immediately.
The only concern I have is during power cuts my ha on pi used to become corrupt. I was using an external SSD drive. I'm hoping the dell might die more gracefully? I had a pi juice hat which kept the pi running during outages. What would ups options be for the dell?
Backup port on the inverter?
Have it plugged into that but there seems to loss of power for a couple ms during a power cut
I think you'd need an automatic change over switch to get an uninterrupted switch, not 100% on that though.
I suspect it might be something to do with the fireman switch.. givenergy have a ups mode on the inverter which is supposed to be seamless
I had my fireman switches removed but it seems to be debatable as to the actual regulations to have them apart from the SEAI grant requirements.
Change-over duration is the key thing. For consumer electronics it's sometimes ok to be 50ms to 100ms, but with IT equipment it's supposed to be 15ms to 25ms. Some of the larger Optiplexes have bigger capacitors in the PSU's and they can withstand a higher change-over durations. Look out for a second-hand 800VA UPS, should do it.
I'm going to guess here, but I suspect that the 3EM isn't wired into all three circuits.
See the second image in the wiring diagrams above... it shows that L is wired into inputs A, B and C and I guess that your unit is only wired into C; hence EM1 (input 2, or C) is showing a voltage and power while the others don't have a voltage reference so can't calculate the power.
I accidentally simulated a power cut on it last night. Had it in an energy monitoring smart plug and forgot I'd a schedule set on it. All powered on fine this morning. Hopefully means no need for a ups..
