ESPHome device wifi connection issue

phillie05 · June 26, 2025, 1:22pm

I’m having trouble getting my device to work. I flashed my config with the device connected directly to my Raspbery Pi running Home Assistant and it says it’s online, however it shows this error in the logs…

INFO ESPHome 2025.6.1
INFO Reading configuration /config/esphome/keg-manager-1.yaml...
INFO Starting log output from 192.168.1.154 using esphome API
INFO Successfully resolved keg-manager-1 @ 192.168.1.154 in 0.000s
WARNING Can't connect to ESPHome API for keg-manager-1 @ 192.168.1.154: Error connecting to [AddrInfo(family=<AddressFamily.AF_INET: 2>, type=<SocketKind.SOCK_STREAM: 1>, proto=6, sockaddr=IPv4Sockaddr(address='192.168.1.154', port=6053))]: [Errno 111] Connect call failed ('192.168.1.154', 6053) (SocketAPIError)
INFO Trying to connect to keg-manager-1 @ 192.168.1.154 in the background
INFO Successfully resolved keg-manager-1 @ 192.168.1.154 in 0.000s

wifi setup in yaml looks like this…

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  use_address: 192.168.1.154

Maybe my IP address is incorrect? If I remove that line the device appears offline.

tom_l · June 26, 2025, 1:24pm

Remove that. Replace with:

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  manual_ip:
    static_ip: 192.168.1.154
    gateway: 192.168.1.1
    subnet: 255.255.255.0

The “use_address” option does not set a static IP. It is for overriding a set static IP address when changing the address. e.g. if you successfully use the config above then decide you want to change the ip address to 192.168.1.42 you would do:

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  use_address: 192.168.1.154  # use this to contact old address
  manual_ip:
    static_ip: 192.168.1.42 # programs new address
    gateway: 192.168.1.1
    subnet: 255.255.255.0

After a successful OTA you then delete the use_address from the config.

Thanks for the quick response. I updated the file but I still get the error. This is what I get in the update…

Can you see what address the ESP currently has by looking in your router’s DHCP assignments?

Also is this actually your gateway (I guessed)?

gateway: 192.168.1.1

phillie05 · June 26, 2025, 1:44pm

Do these screenshots help?

It won’t let me upload more than one image. Router is 192.168.1.1

tom_l · June 26, 2025, 1:46pm

Good that is your gateway.

Is the ESP device listed?

phillie05 · June 26, 2025, 1:49pm

It’s listed under ESPHome Builder tab

On my router all I see are these…
homeassistant 192.168.1.151 DHCP
homeassistant 2600:4040:9ea2:6f00:9af1:2e11:b47c:be26 NDP

You are trying to update over the air (OTA) not using the serial/USB port. You need to direct connect the first time.

When you go to install do not select “wirelessly”. Select “connect to this computer” or whatever it says like that.

After that flash you can then use OTA.

phillie05 · June 26, 2025, 1:57pm

Okay plugged directly into the Pi again and ran an install…

tom_l · June 26, 2025, 1:59pm

Looks like it.

tom_l · June 26, 2025, 2:00pm

Check if your ESP is in your DHCP list now.

phillie05 · June 26, 2025, 2:06pm

I’m not seeing anything there that looks like it would be the device. Would it have the name I gave it? “Keg Manager 1”?

phillie05 · June 26, 2025, 2:21pm

I see a wlan0 device might that be it?

tom_l · June 26, 2025, 2:39pm

Is this the ip address?
192.168.1.154

phillie05 · June 26, 2025, 2:40pm

the ip address of that device is 192.168.1.190

tom_l · June 26, 2025, 2:41pm

Then no that’s not it. Did home assistant discover it?

It might help if you share the full device config.

phillie05 · June 26, 2025, 2:47pm

Here’s my device config…

esphome:
  name: keg-manager-1
  friendly_name: Keg Manager 1

esp8266:
  board: d1_mini

# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: "Umb+W4fVdaTt/VFFAsf3lHtO2QFzcWC7Yi4xyXxuKMM="

ota:
  - platform: esphome
    password: "f4f1932374cab6d47206b7c8c5fc29aa"

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  manual_ip:
    static_ip: 192.168.1.154
    gateway: 192.168.1.1
    subnet: 255.255.255.0

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Keg-Manager-1 Fallback Hotspot"
    password: "KODPzbaeusMI"

captive_portal:

    dout_pin: D3
    clk_pin: D2

    update_interval: 5s

switch:
  - platform: gpio
    name: "Low"
    id: low_led
    pin: D5

    id: med_led
    pin: D6

    
  - platform: gpio
    name: "High"
    id: hi_led
    pin: D7

How do I check to see if Home Assistant discovered it? Sorry I just started using it. I’m not seeing it under the Overview tab, just under ESPHome Builder.

tom_l · June 26, 2025, 2:48pm

Settings → Devices & Services. There would also be a notification icon lower down in the left menu.

phillie05 · June 26, 2025, 2:54pm

Yeah no notifications and not seeing anything there under discovered. I did add the Fios router though. which says my “External IP” is some value. Not sure if that matters

phillie05 · June 26, 2025, 5:08pm

Still no luck connecting. I can plug the device into my Raspberry Pi directly and flash it with no issue but I can’t seem to get it to connect via wifi once it’s unplugged.
