Anyone using an APC UPS in Aus?

Has anyone bought an APC UPS in Austria and been able to integrate it in some way with HE? I don't want to spend over $400 for one of the ones marketed as a smart model.

In the end it doesn't have to be an APC, it's just I have read about some HE drivers and other methods for interfacing with them.

If you are willing to tinker a little bit you can use a Raspberry Pi and Node-Red to integrate it. I had a working example for some time. Still have it working for my unraid server.

Basically you hook up the UPS to the Raspberry Pi via USB. Then put the pi on the network and enable access to the APC Dameon on it. Now with Node-Red setup the pallet for APC and have it query the raspberry pi APCUPS dameon to get the stats. Lastly use a virtual device in HE to pass all the UPS Data.

The hard part is getting the flow to send the status info HE right as doing it wrong can overwhelm the HE hub.

If you want more details let me know.

Does it matter too much which model?

I think as long as the APC UPS has a usb connection probably not. That would exclude some of the really small ones, but other then that any regular retail one should work. I think the ones I test on are like a 1300 kva and a 1500kva which aren't small but certainly nothing special either.

They are also close to 10 years old now.

The pallet in Node-Red I use is "node-red-contrib-apcaccess"

Below is the flow I setup in Node-Red

If you have a Linux server or Synolgy NAS connected to your UPS, you can integrate NUT with Hubitat.

I've decided on a different approach at the moment. I just grabbed a cheaper CyberPower UPS, and using IP Monitoring to monitor lan device for power outage, and then I can guestimate remaining time. Not super accurate, but enough for me to trigger hub shutdown, or record an outage.

Edit: Sorry Cyberpower not Eaton.

I have a couple of cyberpowers (SOHO series) monitored by NUT on my pi 4. (the APC/Eatons that I tested - admittedly many years ago - gave off an annoying hum in use. The cyberpowers were dead silent except when actually running on battery or charging from less than 100%. )

If the APC has a USB B port it will be able to communicate its status (NUT does support APC). The status (battery level/online/mains voltage) is read by node-red which has a NUT node and then sent to HE.

Aye, the CyberPower is nice and quiet. I've got a small one of them, got the brand wrong above.

Thanks guys. Apart from having been interested in stepping into this space for a while, I had noticed that some of the APC UPS' were on special over here. I have ordered two of these at 25% off (2 x $173)

Does that have a built in network card or will you be using the USB port?

From what I've read it has protection for an ethernet connection, but I assume that does not nessecarily mean you can communicate using it via that.

Yeah I meant for the communications interface. I have several APC 750va's that I have the com card in (the cards are pretty cheap on ebay) so I use the LGK driver for them. Works well. I'm looking forward though to @dJOS 's UPS that he's putting together. I don't know if you've read the this thread but this is what he is building with a couple of mods...

yep - surge protection only. All comms are done via the USB port.

looks different than us models, but i have not had good luck with the back ups us models.. either noisy or battery works and only fails with no warning during load ie when wine fridge kicks in.. even if it is not drawing more than the rated watts.

that is why now i only get the smt1500 models, replacement batteries myself every couple of years or when it tells me during the self test.. Those do not seem to fail without warning under load.

also at least in usa you can get the network cards for them reasoneable on ebay for around 40-50 bucks with an offer.. My telnet based driver works for these network cards to get the relatvant info. apc 9630 or 9631 work well.

ie

hopefuly the au models of the backups works better than the us ones...

if you can find an smt1500i cheap/resoneable and add your own batteries and net card i hightly recommend it. i have about 10 between 3 houses.

The problem with this for me is i need a regular outlet in my ups as almost all of my devices i use them for has a kasa/tplink wifi or zwave/zibee switch on it.. The ones for my main network on a backup att access point network.

i like the kasa as they remember state if the ups ever really shuts down with a long power outage and come back in the last state.. many switches i tried do not.. One house is empty and i need to be able to reboot stuff like the hub and wifi etc remotely if they freeze up etc.

Recently i had my main private ip wifi router freeze up .. now i have a spare i can kick in.. but since that is my default gateway I also now had to put all my network switches on a kasa/wifi switch on the backup att network as when i kick in the backup main wifi router the default gateway ip stays the same but the nic address changs and nothing works if the switches are not rebooted.. Way too fricking complicated.

I hope they perform as well. I looked at the SMT models, but at least on Amazon there aren't any available below $1K, about 5x what I paid for the back model. I'm sure there are other options in that SMT range that may become available, or I could look elshewhere, but for now I am happy to give this a go.

Hi @mavrrick58,

I noticed the reference to EventGhost in your UPS driver. What are you using that for, or what does this cater for? I've started using EventGhost on my laptop.

Trust a storm to be rolling through while my UPS is in transit.... No issues yet, so here's hoping it stays that way....

Let us know if it's silent during use. I probably wouldn't mind getting another UPS :slightly_smiling_face:

Will do.

By use are you referring to when I am running on battery, e.g. during a blackout? From what I've seen I am expecting a "hum" when running on battery and when running the regular test. At least before receiving it, that doesn't bother me too much, if nothing else it's an indicator of the fact you are operating on battery, but I guess I'll find out soon enough.
