“In this program, the temperature and humidity values on the display remain static and do not update dynamically. To fix this issue, I recommend using the AJAX technique. This technique allows the browser to continuously retrieve new temperature and humidity data from the server without refreshing the entire page

Hi Sara, thanks for the tutorial! I followed it using a NodMCU with ESP8266 and DHT22, and works as described. However, after a while I cannot access the webserver because I suppose that NodeMCU goes in sleep mode. How can I keep NodeMCU awake without the need of pressing RST button to wake it up? Thanks a lot!

thank you for step-by-step tutorial which runs on my esp8266 with esp8266-20210203-unstable-v1.14.bin firmware. However, main.py exists frequently with the following message. I have searched via google, but it seems that it is hard to solve this. If so, can we use micropython in a stable product? Thanks

Hi.
If you reset the board it will boot up automatically. You can restart the board by pressing the RST button.

Sara

This might be ultra basic, but..
I have everything working, and now I want to power the chip just with a power supply and have it run the code without being connected to my computer. How do I power it and tell it to boot up and run?

Hi Sara,
I’m steadily working through the examples at your website, and they are proving very useful.
Thanks for all the help!
I’m wondering, are you planning on an article on using ESP8266/ESP32 & micropython with the popular Blynk app (which is widely used in Arduino-world).
there are some Blynk / micropython libraries at github and while I have managed to get some connectivity, it is very unstable and unreliable.
Would be great to see a project here.
Thanks & keep up the good work
Philip

Hi.
Use & # 37; (without spaces) instead of the % sign.
Search for its html entity : freeformatter.com/html-entities.html

If i put the humidity above the temperature the formatting is rather strange, anybody else having the same issue?

Thanks.

Well, I was doing a turorial by someone else and he was using a dht22. I only had a dht11 and kept getting invalid reading. After searching, came here to find dht22 data is float and dht11 is int. Changed the type and now my setup is working. Thank you for letting us know the difference between the two.
