ESP8266 based  HomeKit Weather Station BME280

ESP8266 based  HomeKit Weather Station using Bosch BME280 temperature, humidity, barometric pressure sensor.

---

Other version also available that acts as the all new Eve Weather!

For Usage please read the Build Instructions Wiki page!

This HomeKit enabled sensor works the same as Elgato EVE Degree!

Features:

• Temperature Measuring
• Humidity Measuring
• Barometric Pressure Measuring (only in 3rd party HomeKit apps!)
• Custom characteristic for detecting your altitude (used for proper barometric calculation)
• Support for SSD1306 OLED screen
• Switching Temperature Display Units between Celsius and Fahrenheit (also Barometric Pressure between hPa/inHg)
• Downloadable User Manual (via Eve app)
• Reset button
• Data history (not reliable enough, so its beta)

If you don't want to use OLED screen, please install the latest 1.x.x release!

esp8266-homekit-weather-station-bme280-elgato-eve's Issues

GPIOs change

Hi, is there any chance to change GPIOs between wemos and BME sensor, so I can plug it directly to board? BME supports 5v, so I want to be able to connect:
5v <-> VIN; G <-> GND; D4 <-> SCL; D3 <-> SDA

Share main code

Why don't you share the main code?

devices not found

day after several attempts with both main.bin and otaboot I can't connect the device to homekit I tried various parameters like 0x0000 0x1000 0x2000 dio qio both with d1mini and
AZDelivery NodeMCU ESP8266 ESP-12F WiFi Lua Lolin V3 the problem remains with ota from the iphone settings makes you connect to lcm ... but then nothing even after 20 minutes of waiting does nothing with main immediately starts flashing the devices but from settings do not see what could be iphone with ios 13.6.1 thanks

ESP32 Support

Hi!

It is possible to compile this for the ESP32? I noticed there is no source code in this repo.

I'm especially interested in the 1.x version (so without an OLED).

How to turn the display off?

The display works all the time. How to turn it off? The switch connected to gpio0 and gnd does not work.

Adjust temp

My Temp is reading 26 but the room is at 24, I cant find any way to adjust the offset.

Also, Working perfectly, Thank you for your efforts on this, its awesome.

Question: Bluetooth active or not?

Hi, as the headline already says, my question is if BT is activated or not?
The reason why I'm asking is, I have a BT device which I neither cannot identify nor that I'm aware of one.
Thanks.

Share

how about some source code....

[Client 3] Failed to compute SRP shared secret (code -2)

Idea: Adafruit BME280 and i2c address 0x77

The Adafruit BME280 uses i2c address 0x77 by default and must be manually set to 0x76 with a jumper, or the weather steation won't work. I knew the problem and the solution, but maybe you should also scan for 0x77.
Great project and thanks a lot!

No visible access point

Hi i have flashed Wemos with >v2.0 soft and on any of them Wemos can't broadcast wifi signal. On v1.0.4 everything is ok. What is the problem?

Device stop responding after few hours

Hi, using the latest firmware I get “Not responding” in the Home App every few hours. I tried a different ESP8266, same result.
I can only get it to appear again by resetting the device holding GPIO 0 to ground for 10 seconds but after few hours I get the same problem over and over again.
If I use a serial monitor I can see the ESP8266 correctly getting the temperature and the humidity and no error whatsoever.
No HomeKit devices have this behavior. Any ideas? Thanks a lot.

Thanks for your repo!!!

Thank you very much!
I'm studying ESP8266 and Home Kit as a Chinese.
I can build my own temperature sensor through your ideas!!!
Through your project, I have learned a lot about ESP8266. Thank you!

非常感谢！
我是正在学习ESP8266和Home Kit一个**人。
我可以通过你的想法建造自己的温度传感器！！！

通过你的项目，我学到了很多关于ESP8266的知识，谢谢！

Newer version without OLED-display?

Hey there, first of all thank you so much for creating this! Is there a way to run the newer versions without an OLED-display? So far I haven't had any luck... Version 1.0.4. works perfectly.

Greetings, Lucas

3D printable case

My PCB's are coming in a couple of weeks.

Any idea on when the STL's files will be available so I can print it?

Really looking forward to building this 🥰

AP-wifi password for HomeKid-... with main.bin

Hello, trying to install this nice build.

Thank you!

2.1.4 - can not connect to my Wifi

After flashing my NodeMCU V3:

esptool.py -p /dev/cu.SLAB_USBtoUART erase_flash
esptool.py -p /dev/cu.SLAB_USBtoUART --baud 115200 write_flash -fs 4MB -fm dout -ff 40m 0x0 rboot.bin 0x1000 blank_config.bin 0x2000 main.bin

I connected sensor and display and powered up with USB adapter. Access point HomeKidd requie a password when I connect form iPhone, but MacBook can connect without pass - is it normal? Auto openning website not working. I opened 192.168.4.1 manually, choose my wifi and paste the password. After 20 min waiting for a connection device to my network - I give up. After some reboots and reflashing - nothing changed

History of data in Eve.app

Hi! 👋 I cannot see history of measurements in eve.app, could You add this functionality?

Question: Which BME280

Hi,
I'm now starting to order all parts for the PCB and I'm wondering which BME280 I have to take, 3.3V or 5V.
I think it is 3.3V but all parts I searched for have 5 pins instead of 4 as it is shown in your drawing.

Can you please help me out? Maybe add this information also in the parts list.

Thanks.

didn't work for me

Hi! I'm trying to copy you project with esp8266 NodeMCU. Did all as you wrot in wiki, but ...

Flash is allright, but ssid did't see.
Can you help me ?
Sorry for my English, just yet study.

1,3 OLED need to calibrate

I tried firmwares v2.0.5, 2.1.3, 2.1.4 but they not working with my 1,3 OLED display from diymore (aliexpress).
When device is powered up - there is a lines or somesing like on the screen. In few bottom rows image changes. I think, it just need to move up more than a half of screen.

Battery operated?

Have you tested this with any sort of battery?

SSD1306 Only?

Is it possible to use a different (bigger) display?

I would like to get a bigger display to view the data from further distance.

Optional second sensor?

Hello again, I just wondered wether it would be possible to add a secondary (optional) sensor? My use case would be:

1. Fridge/freezer temperatures
2. Inside/outside temperatures

I would be more than happy to help out if something is required!

Greetings, Lucas
