    You can do this with the API if you want to. Should be quite easy to set up on it.

    I just automated some motorised blinds I have. I ripped apart the remote control and wired an 8 relay board to simulate button pressing. I can now raise and lower the blinds depending on events.....works magic :-)

    Neopixel

    Would it be possible to implement neopixel control? This is a rally easy way to get some rgb lighting

    Small bug if with latest beta 142 (i think it's been there since before 103 as the only reason i figured it out was i remembered i had to do it last time i updated)
    it only for the few of us that use a USB Connection
    in the arduino code for serial boards
    the first time you list Serial.begin(9600); where 9600 is the value it takes from the config page but the second time you list Serial.begin(115200); where its hard coded to 115200 so it won't connect unless you happen to have selected 115200 as your baud rate for the board in the config

    Integrate DHT11 Temperature Humidity Sensor standard sketch

    Hi Greg,
    Would it be possible to integrate the DHT11 in the standard sketch? I have several boards with this sensor on it. I do not remember now but I had to use the custom sketch to integrate this DHT11 sensor to the board NodeMCU. Since I was successfully integrating the LCD display with this board, it would be great to gather the value from the DHT11 sensor as well. This feature would be fantastic. By the way, I was impressed by the ability to easily use events to send notifications on the LCD, great job.

    Thanks,
    Aldo

    Are you using the API sketch or the standard sketch?

Do a search on ESP8266 OTA and you should find some descriptions and examples. I'm not sure it would run on the wide variety of Arduinos and ESPs in this community. If I remember correcty, you have to have enough extra memory to hold the entire new flash. I've been lead to believe the ESP8266 nodeMCU has enough.

    I currently have 10 nodeMCUs installed. 9 are in production and 1 is always on the bench for testing and development. It is a real pain to go to each one and load a new sketch.
    There a couple of videos that show how to do the OTA.

    Andreas is very knowledgeable and makes great videos. He is my "goto" guy for 8266 and soon to be ES32 information. I have not done the OTA, but it is definitely in my plans.

    I get mine at aliexpress. They are currently $3.48 with free postage. The only downside is that you have to wait for the order to arrive, as much as a month.
    That's why I stock up on these things

    I once got some of the LoLin V3 nodeMCUs. They were too wide to breadboard but I still used them. Seems to me their wifi is not as strong nor as reliable. Might have just been the batch I got.

    Actually really simple and works for what I wanted. I use mine to monitor the plastic overflow pan that the water heater sits in.

    I took a piece of sponge about 1" square and about 1/2" thick. Then I took a piece of speaker wire (2 wires) and stripped about 3/4" on them both on one end. Then tinned those 3/4" bare wires. I the wires into the side of the sponge about 1/4" apart. Then attached that to the nodeMCU on a digital pin. I treat it like a switch. Either HIGH or LOW.

    When everything is dry, there is no continuity between the wires in the sponge. When it gets wet, the water creates enough continuity to seem as though a button has been pressed. I tested it by putting a little water on the sponge. When it soaked in, it triggered.

    The only downside is it can take a day or so for the sponge to dry out.

    Which 8266 module

    I've really been having fun adding new boards through out my place. This environment is so cool. Thanks for your enabling.

    One thing that I don't look forward to is adding a new nodeMCU. I have this standard set of devices that get added but are not always used on each device. So far I'm up to 12 I think. Let me list them.

    Input 1 Motion (PIR or Ultrasonic)
    Input 2 Door/Window mag switch (HIGH or LOW) doubles as water leak sensor
    Input 3 Temp (DHT11)
    Input 4 Humidity (DHT11)
    Input 5 Heartbeat (updates each 5 mins)
    Input 6 Wifi dBm (updates each 7 mins)
    Input 7 Button1
    o
    o
    o
    Input 12 Button 6

    It would be neat if I could clone another board's devices instead of having to add each one. I do clone the sketch myself rather than downloading. I manually set the mac, ip, port, board id, ssid and pass. Quick and easy.

    Hope this makes sense.
