Don't you find that the DHT11 reads why high when mounted to a board, especially beside a voltage regulator? I tried this with the little $4 China DHT11 ESP8266 modules, and was getting very high readings until I unsoldered the DHT11 and moved it away from the board on a short cable.
Yes that is true I did not realize this until after I had made the video and left it on for a while. This device should have a thermal barrier or something to keep heat away from it. I found that standing the device upright instead of having it lay down on the board helped a bit but it still got the heat through the connections. I would suggest some copper pours on the bottom side of the board and some via stitching to relieve the heat and move it away from the device. Good catch. I hope everyone sees this comment.
Thank you for your video I know it's passed some time but have you, by any chance, updated your software to ArduinoJson 6? I am having a migrane to debug the publishData() Help!

Did JLCPCB provide you with a fully assembled board (headers, resistors, chips and USB plugs) or you had to order them and solder yourself? I'm also thinking that the ESP requires 3.3v and the USB provides 5v so a step down converter is also required.
Thanks for the comment. As of now JLCPCB does not have assembly service but I asked them about it and they said they would maybe have it in the future. Currently they just do PCB fab and then I soldered the components on them once I got the PCBs. You are correct and there is an on board linear voltage regulator to take the 5V down to 3.3 so as not to damage the ESP.
Well I was not able to find a specific command, of course I did not look extensively lol, so I simply just made a conversion and stored it in a different variable and then I sent that fahrenheit variable over MQTT instead of the Celsius one. Hope that helps.
HI, is it possible to do the same with the Aqara Zigbee temperature and humidity sensors? I mean, these ones: it.gearbest.com/access-control/pp_626702.html?wid=1433363 Used with the following controller: it.gearbest.com/living-appliances/pp_344667.html?wid=1433363
I have not used these and thank you for mentioning it to me. I love seeing new devices. I would imagine that you could use them as well since there are Zigbee interfaces and I just now checked on home assistant and found that they support these devices as well. I have reached out to the company to see if they would like to send me some of their devices and we can take a look at them on the channel. Thanks again for the question and the idea.

is there away of editing the temp settings form web page ??

thank you, just automated our bedroom fan
Nice! I am glad you found the information useful. Thanks for the comment!

How do you get it to display Fahrenheit not Celsius?
