Try the white connector on the side, the three pin one! Usually this is the serial and power connector. The middle should be the RX pin.
View Instructable »CN2 in the back of the module can be used to connect this module with Arduino Pinout 1=Vcc 5V2=RX (this should be wired to pin 7 of Arduino board) 3=GndUse external power supply because the module requires up to 0.8A which cannot be supported by Arduino 5V PIN

You have to forward the web server port (8080 in my example) and access it from anywhere.http://YOUR_IP_ADDRESS:8080 (or you can setup a dynamic DNS and use the dynamic DNS instead of IP)

It's not so hard.. you can add an if statement to the codesomething like :if (temp >22) {// enter your action here} is just fine.

Great and straight forward approach! Than you mate.

Sorry for replying late to your messages... It seems that notifications went to spam folder.As I can tell you are OK with the firmware. It is strange, nodemcu-build is quite stable service I'm using it for a long period without problems.Please notice that UDP server part is going to be changed soon so rebuilding the firmware in the near future will cause "PANIC" messages with the current lua code. I will update the source files with new compatible version. As for the moment he code is working.

Well, I thing your are OK!You can issue a print command to see the time on the serial output on SELENE.That is: print((gmthours)..":"..(gmtmins)..":"..(gmtsecs).." "..(gmtdate).." "..(gmtmonth))If you experience any problem just restart the module and check if it is connected to your wifi correctly. A get ip (that is: print(wifi.sta.getip())) command it will return ether your IP details either nil, which is actually means no connectivity.If you like to get every second a line with the calculated time just un-commend the line 29 on "doloops.lua" file. or use the one provided in the link belowhttps://mega.nz/#!WQxXnIjZ!R90v-NWv9wu1TxK5QU5nssE...Keep on!

Probably because wifi module was changed and init.lua needs some update.Try to use the following init.lua file: https://www.dropbox.com/s/q47x4jb28w3c2zd/init.lua...

Thanks for you message.Modules required by the code are: bit, file, GPIO, I2C, net, node, PWM, timer, UART and WiFi.

Very good project! Congrats.I love lua and nodemcu, so it was fun to create the project and play with the code.I do have some comments, though:1. You should use nodemcu's the "float" build in order to get decimal values as well.2. The code (weather2.lua) can be improved, in order to display updated weather info. In current implementation the web request runs once and then you have to restart the module in order to get updated info. By splitting the code in two lua files, one for the request and the other for the web server you can run the request as many times you like (ok there are limitations applied by weather service). I personally have spitted the code in two files and I have created one more file (an init.lua) to setup the module at startup and start a timer. Wemos seems t…

HLK-RM04 documentation is very limited. you can't use it to avoid Arduino usage. If you like a different solution you should go to ESP-8266
VFD's are cool!
