How to add information from dht11 sensor that is connected to pi 5 which hosts my home assistant?

[formal oar]

I am trying to somehow display information about humidity and temperature in my room on web based interface so it looks nice but I don’t know how to do that so I would need full guidance. Would anyone be willing to help me?

[sterile flax]

have you connected the dht11 sensor into home assistant already?

[formal oar]

No, I don’t know how

[formal oar]

It’s connected to server that hosts home assistant

Hi @formal oar,
That usually doesn't go well because adding code to HAOS backend is not supported.

Maybe you can find a Custom Integration or Add-on to do that, but I don't know of any.

You'd be better connecting it to an ESP

[formal oar]

I am using normal Linux and not home assistant os

[formal oar]

How would I do that?

[sacred sorrel]

With an ESP and ESPHome or Tasmota

[formal oar]

Still don’t know how and what does esp mean

But I do own arduino uno

Something like a ESP32 or ESP8266. They are microcontrollers similar to your arduino but with WiFi.

[formal oar]

I don’t own those things but I own another raspberry pi

Exactly raspberry pi zero 2

You can get it for 5 bucks on aliexpress. Personally I'd just get a zigbee hygrometer instead.

[formal oar]

Well, I want to do it myself

Arduino doesn’t support WiFi but I could use pi zero as thermometer

[sacred sorrel]

If you want to do it yourself then ESPHome + supported hardware is the easy DIY route

[formal oar]

How do I configure it?

[unique rune]

ESPHome is a system to control your ESP8266/ESP32, with a native integration for Home Assistant.

You can find their documentation here, and get help with ESPHome itself here in the #diy-archived channel (#integrations-archived for the Home Assistant side integration with it). They also have their own Discord server too.

Ready to use custom firmware for ESP8266 devices (including Sonoff)

Docs:

They have their own Discord server or you can ask in #diy-archived

[formal oar]

My raspberry pi zero 2 isn’t listed on website

[sacred sorrel]

That's expected

Pi != ESP

[formal oar]

Well, I plan to use pi zero 2 as thermometer and pi 5 as server which would collect data

[sacred sorrel]

That's the hard DIY route, is there a reason you want to go that way?

[formal oar]

Because I already have pi zero and hardware needed? I don’t want to overpay

[sacred sorrel]

Then you're going to have to find/write something to read from the sensor when you connect it to the Pi Zero, and send that data to Home Assistant (eg over MQTT)

Or spend some $5 to buy an ESP

[formal oar]

Would this work?

Maybe... hasn't been updated in 2 years

How did official gpio addon work?

Because I managed to find custom verision of that addon

And that addon is updated
