Great video KP. love the simplicity. I have them in every room of my house, also In the attic, outside under a covered porch, and in the garage too. They work great. I keep the sensor away from the board because the module gets a bit warm and I wanted open-air temp and humidity. Also, don't forget to back up and save each ESPhome device config just in case...

Great tips & Great comment! Thanks :) Are you using exactly DHT22 sensors?

Thanks for the video. I did have some initial difficulties and learned 2 important things: 1) if you are using a raspberry pi with Home automation already, and are using Zigbee, you may need to disconnect the zigbee dongle while first configuring the ESP. The SB ports on my Pi were very noisy. Once configured and running on wifi, no problem. 2) I needed to add a 4.7K pull up resistor (as suggested by some others if I was having difficulties. That helped the reliability of the DHT a lot.

Great tutorial for people still scared of ESPHome and boards. FYI, you couldn't do an OTA install because your board wasn't on your Wi-Fi yet. After the first flash you can do all updates OTA.

Thanks for the comment and for the tip 👍

I use to make my own sensors., adding light sensors, motion and the temp and humidty all in the one device. Some even had LED's I could use as night lights. I loved it in many ways, but these days a lot of ZigBee sensors, like the little Xiaomi ones, are just as cheap and also local (no cloud needed) so I stopped doing it. Not to mention the fact the ZigBee ones can be battery and last a while between changes. That said, really great to see a new video on how to do all these sort of sensors. Most of the videos on KZread are not very recent

Yes, battery sensors that are working with HA locally are no brainers. Thanks for the comment Brendan!

Thanks for this, I had a great fun setting it up. Mine was giving me very wrong readings. I had to add this line to the ESPHome config and reflash it to fix the issue: "model: AM2302"

DHT22 is good for temperature readings, the humidity though started to fail on me after a year, reading 99% almost all the time. Probably because i smoke in the room, gonna try some methods to revive it. Nice video as always, Peyanski, thank you very much!

Hi thanks for the video, very usefull. Sometimes you need to add this line: "model: DHT22" too, otherwise you will get strange readings (at least for wemos D1 pro).

I couldn't get my temperature readings to go off. I realized you needed to "install" the changes, if you edit the yaml afterwards. Did an update or install, and got the temperature/humidity readings right away.

Great video Kiril! Last week my wife asked if I could make a temperature sensor to put in my daughter's school bag to track how cold the classroom at school was getting. Sure I said... thinking about how best to power a pi or an esp. Gee it grew into a major exercise! If I go esp I need a sd memory module and a clock module on top of figuring out power... This might take me until the summer! I will keep you informed :)

Just got into Home Assistant, have been using your videos for guides! Thanks for the help! 2 questions. First, the dht11 appear to be slightly cheaper (I'm prefering amazon for now so I don't have to wait so long for shipping). Will these work/is there a draw back to these? Question 2. Instead of powering these with micro usb, can they be spliced into say an led strip that's running off 5volts? Thanks again for all the help!

@@KPeyanski Haha, thank you very much :) I do have one problem. Initially, when connected to my Raspberry Pi, right after installation, the sensor reads pretty accurate data. But as soon as i disconnect it from the Pi and reconnect it to the Pi or use a Power Adapter to plug it into my wall outlet, it reads temperatures at -10°, which is far from correct. So it seems like, disconnecting and reconnecting somehow "destroys" the readings permanently. I have tried different wall outlets and different Power Adapters. But they are all 5V adapters, which should be fine according to the ESP documentation. Any Idea what is wrong here? :P

Could not connnect to board through ESP Home with any method. I always run into problems lol. Can use Arduino IDE software with no issues tho. Any way to integrate my device into Home Assistant after setting up with IDE?

Might be a dumb question, but I'm learning so maybe others have it as well...I've set up a few ESPresense esp32 devices and those have been fun to play with and add automations for. I've gotten this now thanks to your video (thanks, as usual)...can 1 single esp32 board (or any of them) manage ESPresense and Temperature and Humidiity, or not possible? Just curious, thanks as always for the great videos!

Decided to build this and was surprised that in my yaml pin: 2 is entered yet the physical wire is on D4, why is this working thought the data pin was supposed to be D2? Also can't type in D2 under pin it doesn't like that so I have to enter just 2?

¡Gracias!

What if i wanted to connct more than one temp sensor for accuracy? How do i connect it?

I did this same setup. I tried out 6 different dht22’s and 3 different boards. The temperature was consistently lowat about 14 Celsius. And humidity stayed around 5-15%. When in reality temperature was 22 Celsius and humidity was 49%. What could be the problem?

Hi i don't have raspberry pi. can we use arduino uno instead?

I want to add pH and EC sensors in esp8266/home assistant

When I place my device in a case, the temperature reading is higher than it actually is. Can I adjust this in any way?

Can I use DHT 11 sensor?

This may be crazy, but what i really want is a body temperature sensor to turn on the air conditioning if I myself get too hot

Nice tutorial, I made 3 sensors like this, they only work after pressing the reset button on the d1 mini once (if not they read completely off values like negative temperature and 20% h). And also they become unresponsive after some time or I think after a certain number of reading. Do someone know why ? (I don't use resistors)

@tartine3966

So I found that adding "model: DHT22" after "platform: dht" makes the sensor read correct value right from the start without pressing reset. No more negative values. If the time out issue persists I will be able to toggle the usb power because I plugged them on a smart switch.

In ESPHome 2023.3.1 it is not possible to choose "Pick specific board". Only ESP8266 and ESP 32 is available. IS there a work around?

@@KPeyanski the thing is, I don't use a home assistant, only a homebridge ... I want to make a table control with 3-4 switches and a thermometer. This method with ESPHome in HA seems quite simple to me, but if there is a homebridge or homekit device, I am referred to the finished FW on github ... I found something, but not exactly what I want ... only to make each device special and that seems unnecessary to me. 2x ESP, 2x networked devices, and all in one box. One board does it too ... in creating FW for homebridge or homekit, I don't know that at all ... is there a similar guide as for ESPHome in HA? or another option how to make a simple DIY FW? thank you and apologize for the unnecessary questions 😇

No pull up resister used. According to the document there needs to be a pull up resister between data pin and esp
