Cannot connect to WiFi

Open gergelyz opened this issue 1 year ago • 8 comments

I have 4 EP1s, when suddenly one of them disconnected from WiFi and could not reconnect. I tried reflashing and updating the firmware via USB which was successful. However when I am prompted to enter my WiFi credentials and the ESP is trying to connect I receive an "Unable to connect" error message: Screenshot 2024-05-01 144815

I tried to connect multiple times but still receive such error. All my other EP1s are working seamlessly and can connect to my WiFi.

Try unplugging and plugging back in and then connecting to WiFi again (no need to flash again)

Hi, it seems I have a similar problem.

Yesterday I noticed that the LED of my EP1 was flashing in red. I've unplugged and plugged back in, but it didn't change anything. I looked at Home Assistant and I saw that no information is reported to HA (probably because he couldn't connect to the network).

A few days before the issue, I've flashed the EP1 to have the latest firmware, so I've tried to flash again to see if it changes anything. The flashing process was successful, but when I'm prompted to enter my WiFi credentials, I have the same "Unable to connect" error message.

For information, I have a Ubiquiti Networks, with a U6 Lite wifi access point. I didn't change any parameters in my network config. I have several wifi networks and my IoT network has a space in the name, so I tried an other network with a simple name => same error. I've just tried to enable an access point in my phone on Android and then the EP1 successfully connects to wifi.

Unfortunately I can't leave this configuration with my phone but it might help to identify the problem.

Thank you @Ptitpim, I had the exact same experience as you described and went through the same procedures.

  1. LED was flashing and no data was reported to HA
  2. Tried unplugging & plugging back in which did not resolve the issue
  3. Tried to flash the firmware again which was successful but could not connect to my WiFi. Same as you, I could connect the EP1 to my phone's access point. As a last resort I tried flashing a generic esphome web to the EP1 which allowed me to connect to my wifi successfully. Then I tried to manually OTA install EP1 firmware which was successful, as it was reporting values to HA again. However when I unplugged it and plugged it back again, it could not reconnect to wifi so I was back at square one.

Same issue for me, tried flashing firmware from repo site and ESPHome integration in HA, can't connect to wifi. Logs below.

Is this still an issue on newer versions of ESPHome?

The issue has just started happening for me on the everything presence lite

I'm experiencing this issue with both of my EP1s. They have been working for years, I noticed within the last couple weeks they went offline. Unplugging/re-plugging doesn't not fix the issue. Re-flashes them with through the web flasher via EP1 docs, they connect the first time and work tethered to the PC on initial setup, but once I disconnect them and move them back to their assigned locations they no longer reconnect to WiFi or home assistant.

Have you changed anything on your network recently? New router, mesh node? Or changed any seemingly innocuous settings? I had the issue with the EP Lite after adding a new AI Mesh node then after changing some settings (and changing them back again) it worked!

Shadyfox911 avatar Aug 23 '24 15:08 Shadyfox911

@EverythingSmartHome i bought 3 presence lite in december. I booted the first and connect it to home assistant and wifi with no problem. It worked some days and then I installed the last firmware update via home assistant (1.0.6 -> 1.2.0). Now i see the integration to add the esp to home assistant, but I can´t connect to Wifi - i´m getting the message, that I have to press a authorization button to connect image

I disassembled the lite and tried both buttons, but it did nothing (which button is reset and which is boot?).

For the second one I tried to flas the newest firmware 1.2.0 first. With the esp-tools on your website I flashed the newest firmware (multiple times with and without bluetooth proxy). I had the same problems in home assistant and when I try to connect with yout esp-tools on the website, I am getting the same "unable to connect" like above.

Then I created an guest wifi-network and i can connect to this wifi. But I can´t use it because of the network seperation.

What can I do to fix this problem? I have the newest firmware installed but I can´t use them anymore. Are there maybe some character in the ssid or the pdw that are not supported? It would be very painful to change one of them for me.

The firmware doesn't need an authorisation button so if your seeing that message then I'm guessing you might have installed another blank firmware possibly?

The real issue is most likely this: https://github.com/EverythingSmartHome/everything-presence-lite/issues/246#issuecomment-2496173013

Please post over in the Lite repo in future, this is the EP1.

EverythingSmartHome avatar Jan 12 '25 17:01 EverythingSmartHome

I flashed the firmware from your website: https://everythingsmarthome.github.io/everything-presence-lite/updating.html#manual-setup-and-factory-resetting I try to find issues with my dns and will continue in the other repository. Thanks :)

MrBeats avatar Jan 13 '25 21:01 MrBeats

Just an short update - I tried an differend dns but this also doesn´t work. After I flashed the firmware 10-15 times without any result, I installed arduino studio to see the logs throught the serial port. The logs looks good but next time I flashed the firmware it worked without any problem and connect to my wifi. I don´t know why but maybe it help other persons.
