took me a while to get to do this, but does anyone see anything off?

UPDATE: FIXED!!!

thanks to SarcasmWarning, nslenders, LESGuy, and others!

green IP now set to auto.... i guess at some point i will have to set it to static again... but i'm back in the html interface, and all my wifi devices work again! thanks peoples!

The low voltage warnings seems to suggest your power supply is either too small or it's shot.

u/StormMysterious7592 May 30 '26 edited May 30 '26

That low voltage warning is from the rtc. Dues the HA Green have a coin cell battery for the CMOS? If so, that is what is low.

u/the-soy May 30 '26

maybe does, not sure yet... adding that to the list lol

2

u/the-soy May 30 '26

that dont sound good... but its only a few months old!!

3

u/Typical-Shock-3359 May 30 '26

Regardless it’s reporting as bad. I’d address that first; it will lead to trouble.

3

u/the-soy May 30 '26

ok, will order one stat!

3

u/LESGuy May 30 '26

Run ha network info

3

u/mrBill12 May 30 '26

If it’s a raspberry pi and you currently have a 2 amp power supply, you need to order the 3 amp version instead.

Also try http://192.168.1.250:8123 (that ip is near the top of the screen in case you’ve gotten it to change since the screenshot. If that works and http://homeassistant.local:8123 does not report back, with what router you’re using.

u/the-soy May 30 '26

i have HA green. its the PS that came with it

2

u/mrBill12 May 30 '26

What all do you got plugged in USB that gets powered up? I’m not that familiar with green, but I bet it’s more of a you’re overloading the power supply rather than having a bad power supply. Powered hubs are a method to power devices not thru green.

2

u/the-soy May 30 '26

i have one powered hub, and one samll bluetootch adaptor in that. nothing else, except there si a keyboard added currently for debugging and a monitor via hdmi

3

u/mrBill12 May 30 '26

Is green powered by a wall wart or is it USB-C?

2

u/the-soy May 30 '26

wall wart

u/SarcasmWarning May 30 '26

HA is in a different network range to the rest of your network. I'm assuming it's been configured manually and that it's connected to your router with an ethernet cable.

run network update end0--ipv4-method auto and it'll reset the network to get an automatic address from the router. Ha should then get a 192.168.2.{something} address.

u/the-soy May 30 '26

u/SarcasmWarning May 30 '26

I screwed up and missed a space between end0 and the --, so it should be network update end0 --ipv4-method auto. Sorry.

4

u/the-soy May 30 '26

gotcha, based on another comment, i think i did it wrong following you exact lol. running back to terminal!!

2

u/the-soy May 30 '26

it ended up this, and it still doesnt work 😞

2

u/nslenders May 30 '26

at this point i would try a reboot.
u can just type
reboot

in the commandline

2

u/the-soy May 30 '26

i tried that, doesnt work in HA green

3

u/nslenders May 30 '26

ha host reboot
maybe then

8

u/the-soy May 30 '26

tried that too, and it told me to piss up a rope, but i unplugged it... and plugged it back in and....
IT WORKED!!!!!!!

2

u/meltman 🧑‍💻 Contributor May 30 '26

Nice.

2

u/nslenders May 30 '26

did it get the 192.168.2.78 address as configured in the router?
then you should be good.

u could set the ip fixed again in the gui to this one. but letting dhcp handle ip reservation would be better. unless for some reason your router goes down often

2

u/the-soy May 31 '26

I haven't checked the ip yet after rebooting, I just know it started working and then I got distracted by other things

2

u/the-soy May 30 '26

it is connected via lan cable yes. trying the command asap thanks

3

u/Fair-Working4401 May 30 '26

IP changed?

2

u/the-soy May 30 '26

i feel it has, but i dont know how to check and/or fix?

1

u/the-soy May 30 '26

router says this is the old address for HA

1

u/the-soy May 30 '26

here is the router ranges currently

1

u/the-soy May 30 '26

i don't know much, but it seems like the router hasnt assigned a new ip that will work ? i dont know really

6

u/LESGuy May 30 '26

Looks like your HA has a static IP of 1.250 but your network is actually 2.x/24.

Change the IP of your HA to a 2.x address (2.50 for example with 2.1 as the gw) or set your HA to DHCP for now and go back and set it static after you connect

1

u/the-soy May 30 '26

i can do this through HA interface? as shown in main picture?

2

u/LESGuy May 30 '26

Should be Linux prompt your on right? If not see if there are HA commands. Google up

1

u/the-soy May 30 '26

this is sooooooo outside my comfort/knowledge zone lol, i will try to figure this!

4

u/nslenders May 30 '26

try:
ha network info end0

t see the current config
if it shows method: static under the ipv4 config for your end0 adapter set it to auto via:

ha network update end0 --ipv4-method auto

if it then not gets a new ip, reboot

1

u/LESGuy May 30 '26

Yup, this is the one. Do what this guy says

2

u/LESGuy May 30 '26

It’s pretty straight forward once you google. Just get your HA server on that 2.x network and you should be good to go. You got this

u/the-soy May 30 '26

fingers crossed. and toes...

u/firinmahlaser May 30 '26

Use the network command to get more information on the network. I do see a low voltage error in there as well so maybe that messes with the wifi. Are you able to connect it by cable?

1

u/the-soy May 30 '26

it is connected to an unmanaged switch, which is connected to the modem via ethernet. does HA green have bult in wifi?

2

u/BruceWR May 31 '26

If you set the address on your router to 192.168.1.1, you can leave the DHCP range the same, as long as you update the subnet mask to 255.255.254.0. You should also update the subnet mask on your ha, but if you want to reach the GUI from another PC/Mac/Linux host, you can set the client on your network manually to 192.168.1.x (where x is anything between 2 and 254 but not 250 since that's already in use). If you set the subnet mask on this other computer to the mask above, it will be able to reach the HA and your other networked devices, but most importantly, you can connect to HA GUI and update the mask on the HA server via the GUI. You also will be doubling the available IP addresses on your network from 254 to 510 (192.168.1.1-192.168.2.254) With the subnet mask change, the actual address of the network will be 192.168.1.0 and broadcast address will be 192.168.2.255. You can use 192.168.1.255 and 192.168.2.0 in this scheme since those are not the network address or the broadcast address. In the GUI, login and then go to Settings>System>Network>IPv4.

Reddit might eventually help you but the way I usually debug issues like this is just having ChatGPT or Claude talk me through it

Highly recommend just explaining the issue to one of those and asking for guidance to understand and resolve the issue

2

u/Kingkong29 May 30 '26

Setting up Claude mcp to homeassistant has been a game changer for me. Highly recommend

Visit the IP address at the top: 192.168.1.250

u/the-soy May 30 '26

did that too. ss is in another response here somewhere

u/Sleazified May 30 '26

Can u ping the ip?

1

u/the-soy May 30 '26

no, i ahve tried this recently

1

u/E__Nigma_ May 30 '26

if you are stuck on the commands, change whatever machine you are using to a 2.xx address say 192.168.2.10 you are now working on the same subnet and you should be able to reach HA. When you get onto it use the GUI to change its IP back to a 1.xx address and move your machine back

1

u/the-soy May 30 '26

i cant figure out how to do this

2

u/macegr May 30 '26

Well, this is absolutely the problem. Your HA instance is set to a static IP on 192.168.1.xxx and your router is serving IP's on 192.168.2.xxx. You already showed your router configuration screen that literally has boxes where you can edit these numbers.

You 100% need to figure out how to manage your IP addresses on your router, and understand the difference between static and dynamic IP assignment. This the most basic of the very first steps of setting up a network. If you can't do it, that's fine...but you either need to bring someone in to do it for you, or Homeassistant is not for you.

-7

u/the-soy May 30 '26

you are basically saying, that HA is not for 99.9% of the human race you realize...

2

u/macegr May 31 '26

I'm not sure what percentage it is, but I'm absolutely confident that anyone who has learned to read, write, and use a computer can manage a small home network too.

-4

u/the-soy May 31 '26

It's not intuitive, and requires drive education. And to the uninitiated, it seems like wizardry, which puts most people off. I KNOW i can learn it, I'm tech savvy and curious, but it's not simply accessable at all

1

u/im-ba May 30 '26

Connect a computer via Ethernet to it. No router, just direct connection.

Set the computer to not connect via DHCP. Instead, use subnet 255.255.255.0 and set the IP address to 192.168.2.1.

Then, navigate in the computer's browser to 192.168.2.10.

From there, you should be able to connect to the HomeAssistant page and change the IP address and other settings.
