Room temperature & humidity on Home Assistant using ESPHome and NodeMCU

I don’t see my device which is NodeMCU ESP8266 on Esphome. Do I have to flash firmware manually like you?

thank you for your video, worked perfect

I HAVE ISSU HELP ME PLZ ->Can't connect to ESP. Please make sure your YAML file contains an 'api:' line.

Can I connect multi DHT11 sensor on 1 nodemcu device?

hi, video ist super, nur es funktioniert nicht, seit upfate von esp home. Es gibt keinen "update" button und per USB kann es nur von RASPI geladen werden, nicht vom PC. ESP Home kann zu NODEMCU per WLAN, (als OTA) aber lehre NODEMCU kann nicht als OTA geflasht werden. Man könnte zwar die fertige Datei runterladen, aber wo ist die gespeicherte Datei? Im Ordner "ESPhome" ist es nicht....

Φίλε μου μια και είσαι Έλληνας μπράβο σου για την ενασχόληση σου με το Home Assistant. Ασχολούμαι και εγώ αλλά χωρίς βίντεο , μόνο κατασκευή. Φαντάσου τι διαφορά θα έκανες αν ότι φτιάχνεις στα αγγλικά το έκανες και στα Ελληνικά. Μπράβο για την προσπάθεια σου. Ευχαριστώ.

Well, this email answered all my questions and got me started on the right track! Despite some issues with Silicon mac and ESPHome Flasher GUI not working well together, the CLI got it taken care of.

My text step is I was already using the esp8266 to control some lights based off the temperature. Do you have a tutorial to show how to call “sketch.h” in the yaml file? EspHome’s documentation was a little confusing as to where their code examples should live in HASS

Fantastic video! Thank you so much as I am new to microcontrollers and Home Assistant and I now have temperature, pressure and humidity wirelessly streaming from my BME280 connected to my ESP8266 :) Very easy video to follow.

looks like your github link is dead.

Hey, would you tell me something about your power source? It seems to be some nice DIY power bank...
Btw... everything work perfectly!

I can recommend using ESPHome in Home Assistant, to flash the NodeMCU for the first time. Use the ESPHome Wizard to create the first program and just connect the NodeMCU to the Raspberry Pi. It is very easy :)

Thank you very much for your video: I've created my first project following your instructions! Just two things: EspFlasher doesn't work on osx Catalina (I've tried 1.2 and 1.3 without results), on Windows it's necessary download drivers to connect nodemcu.

Your tutorial are so good and easy to follow. My problem i cant start esphome add on in my home assistant. An error message keep popping up

hai, I connect mcu with relay when I switch ON through H A Relay was OFF and when I ON through H A it was showing OFF history logs also showing OFF kindly provide a good solution

Πολυ καλο το βιντεο, δυστυχώς ομως κατο δεν κανω εγω σωστα.. Και δεν εχω ενδειξεις απο τον αισθητηρα, μου βγάζει τα ακολουθα:
Requesting data from HDT failed.
Invalid readings! Please check your wiring(pul-up resistor, pin number)

Thank you so much for this video, it helped me out so much. My first experience with the nodemcu. I am using this to monitor 4 magnetic door sensors with Home Assistant. I did have a couple issue that I had to overcome if it helps anyone else. I had issues with my PC recognizing the nodeMCU as a serial port. To resolve that, I just had to update my drives for the CP210 uart, just do a search for CP210x_Universal_Windows_Driver. I also had issues compiling my code. This was because I had an older version of ESPHome, so all I had to do there was update from 1.13 to 1.15.3 and that solved my issues. The door sensor's work flawlessly in ESPHome and home assistant!

You can also add a GPIO switch right here in the code just below the sensor if you want. Then you just need a relay and you could control a heater or other device in that room along side tracking the temperature. Lots of possiblities:

switch:
- platform: gpio
pin: 5
name: "Living Room Switch"

Thanks man! My first esphome project was successful thanks to your exact and clear video!

are you from greece ?

Why not just attach the dht sensor directly to the pi's GPIO? That's how mine was set up. If I remember right, I just had to tell HA which pin to read, and it already has the capability to read it.

Hi, i want to try this, but im not sure which cable plug to where, im very new at this.

can i connect more than 1 sensor / relay on esp32?

WHICH IS MORE ACCURATE THE DHT22 OR XIAMOI AQARA?

Awesome video, thank you..
