Room temperature & humidity on Home Assistant using ESPHome and NodeMCU

In this episode we are connecting NodeMCU to the Home Assistant using ESPHome add-on.
Temperature and humidity are metered based on DHT11 sensor connected on NodeMCU and send wireless to Home Assistant This is one of the easiest and cheaper sensor with wifi capability that you can use.

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.

[@PoseidwnTech]

Thank you for your comment! I am glad that our tutorial help you!

[@andrejsersen59]

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

[@PoseidwnTech]

You are welcome! Thank you for your nice comment!

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.

[@PoseidwnTech]

Σε ευχαριστώ για τα καλά σου λόγια!

[@markmacherey4744]

Awesome video, thank you..

[@PoseidwnTech]

Glad you liked it!

[@JaydenThorup]

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"

[@PoseidwnTech]

Indeed endless possibilities!

[@nicklefevere2084]

thank you for your video, worked perfect

[@PoseidwnTech]

You're welcome!

[@lucasassetto]

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.

[@fazrulrusdi3709]

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

[@AndrzejSQ9PKW]

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

[@venkatesanmurugan3931]

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

[@NormRasmussen]

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

[@PoseidwnTech]

Unfortunately we don't have a tutorial for this but we will try to make one!

[@nev0076]

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

[@PoseidwnTech]

Yes first time you have to flash it manually

[@PowerMeep]

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.

[@PoseidwnTech]

With the nodemcu approach you can have multiple sensor around the house that sends measurements over wifi to the home assistant that is hosted in the rpi.

[@gardenredplanet4381]

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

[@ariel3680]

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

[@PoseidwnTech]

It's very simple. You just need to plug + connector of sensor to a 3.3V in nodemcu, - to ground and choose a pin of nodemcu as input.

[@ariel3680]

@@PoseidwnTech can you do the code variation for esp32, i bought the wrong board and somehow unable to flash it

[@holijames82]

WHICH IS MORE ACCURATE THE DHT22 OR XIAMOI AQARA?

[@PoseidwnTech]

DHT22 is very accurate sensor. I have not used xiaomi aqara

[@holijames82]

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

[@PoseidwnTech]

Yes of course you can. You have to use a different pin per sensor and setup accordingly in the yaml file on esphome

[@kalvinwui1154]

Can I connect multi DHT11 sensor on 1 nodemcu device?

[@PoseidwnTech]

Yes you can have more than one sensor. You need to use different pin.

[@billunder7959]

are you from greece ?

[@PoseidwnTech]

Yes we are from Greece!

[@Kostaris7]

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)

[@bag-stg-kft7445]

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....

[@dablet]

looks like your github link is dead.

[@PoseidwnTech]

We checked it and it works!

[@fazrulrusdi3709]

You 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
