ESPHome Knock out Home Assistant OS on an RPi

ESPHome

Hi!

in most cases if I want to use ESPhome on my Raspberry Pi running Home Assistant OS, the OS is totally frozen. Only hard reset helps.

When I added the first nodemcu, the OS is frozen.

After restarting. the esphome found the nodemcu. I sent the first yaml that just set up the wifi connection. The OS frozen again.

Restart, I tried again. Now the esphome wrote yaml (over local usb) and the nodemcu connected to wifi.

I tried to load an LED flashing program to nodemcu over OTA. The OS frozen again.

That’s hard enough to work with ESPhome. What could be the problem? What can i do?

If need information please tell me, and i provide it.

Thanks!

It’s quite normal as ressources on PI are quite limited :wink: If you had done a search in forum before posting you would have noticed quite few guys have already complained about that in the past !
If possible try to use a PI4 with an SSD and not an SD card, it’ll help reduce the problem !
Side note: the frozen system should appear only when compiling, not downloading/flashing !

How do you know?

How is the Pi and the NodeMCU powered?

Lower ram pis commonly freeze up during compilation. You don’t say which model you are using.

Run esphome on a different computer.

Hi!

The RPi is powered by a 3A RPi labelled adapter. The nodeMCU is powered by 500mA computer USB slot.

The frozen: The web page is unavailable, SSH too, ping is working. I’m waiting almost 1 hour to response, but this ha is responsible my house water supply si can’t waiting more.

Hi!

The freeze is not complete, the ping is working. BUT the first 2 “freezing” is not in compliing mode, but only searching the device with ESPHome’s “new device” button. (Clean ESP32 on my computer’s USB slot).

The first “compile” is only:

esphome:
  name: test-esp

esp8266:
  board: esp01_1m

# Enable logging
logger:

# Enable Home Assistant API
api:

ota:
  password: "a13a977ab0008d5905acc27c5d2fa07c"

wifi:
  ssid: hassid
  password: hassidpass

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Test-Esp Fallback Hotspot"
    password: "jQubGxZc9Fi0"

IMHO a weak computer is done this in a half hour… (but i don’t know how ESPhome works in the background) i’m remember that time when a linux kernel compiling lasted for 2 days. That computer is a quartz watch compared to an RPi.
