Hello Im trying to collect data from my WEMOS D1 that read´s the temperature of my fridge and freezer. I have a simple webpage showing the temperature of the devices but can´t figure out how to read the data and use it to update a QA label I think I should be able to somehow just get the data of the three float tempSensor1, 2 and 3? What the HTML page look like: Webbserver part of the arduino code: //Webserver String SendHTML(float tempSensor1, float tempSensor2, float tempSensor3) { String ptr = "<!DOCTYPE html> <html>\n"; ptr += "<head><meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0, user-scalable=no\">\n"; ptr += "<title>Temperature Monitor</title>\n"; ptr += "<style>html { font-family: Helvetica; display: inline-block; margin: 0px auto; text-align: center;}\n"; ptr += "body{margin-top: 50px;} h1 {color: #444444;margin: 50px auto 30px;}\n"; ptr += "p {font-size: 24px;color: #444444;margin-bottom: 10px;}\n"; ptr += "</style>\n"; ptr += "<script>\n"; ptr += "setInterval(loadDoc,1000);\n"; ptr += "function loadDoc() {\n"; ptr += "var xhttp = new XMLHttpRequest();\n"; ptr += "xhttp.onreadystatechange = function() {\n"; ptr += "if (this.readyState == 4 && this.status == 200) {\n"; ptr += "document.body.innerHTML =this.responseText}\n"; ptr += "};\n"; ptr += "xhttp.open(\"GET\", \"/\", true);\n"; ptr += "xhttp.send();\n"; ptr += "}\n"; ptr += "</script>\n"; ptr += "</head>\n"; ptr += "<body>\n"; ptr += "<div id=\"webpage\">\n"; ptr += "<h1>Temperature Monitor</h1>\n"; ptr += "<p>Frysbox: "; ptr += tempSensor1; ptr += "°C</p>"; ptr += "<p>Kyl: "; ptr += tempSensor2; ptr += "°C</p>"; ptr += "<p>Sval: "; ptr += tempSensor3; ptr += "°C</p>"; ptr += "</div>\n"; ptr += "</body>\n"; ptr += "</html>\n"; return ptr;

I am looking for a propane gas detector. The only z-wave version I have found, is the one by eDomotica.com, but they seem to be going out of business. An alternative would be to buy a stand-alone gas detector/alarm, and connect some output signal to a Fibaro Universal Binary Sensor. A third possibility is to build one from scratch, buying individual components for the sensor, the control and the z-wave module.This link, using Arduino, could be a start. Please note that most combustible gas detectors cover natural gas (methane) as well as LPG (propane/butane), but CO detectors are different. Any thoughts (or better yet: experience) on any of these alternatives?

Hi there, I'm building a Nextion touchscreen with a arduino ESP8266 chip. I already can start scene's from the display. I'm now struggeling with a way to communicate back. Is there someone who can tell me how to send value's from a variable in Fibaro HC2 to the arduino ESPchip? I created a webserver running on the arduino and can make different actions on it i.e. /ledon runs a led on script on the arduino. But this way i need to make a different script for every single action/value of a variable. undoable when I want to send temp or lux to the arduino. Is there a way, so yes how, to send the value of a global variable in fibaro HC2 to a global variable in the arduino. Cheers, Damien

I need some help with json decoding. I'm succesfully got the data in HC2 from Rasspery/Pyton but I'm not able to decode that data in HC2. Any advice, please?! --starting LUA code here local smartmeter= Net.FHttp('192.168.1.10'); response = smartmeter:GET("/index.py") fibaro:debug('Answer: ' ..response) --this is the data response coming from Rasppery/Pyton: {"Amp": 13.29, "Volt": 98.01} if (tonumber(status)==200 and tonumber(errorCode)==0) and response~=nil then fibaro:debug('Decoding...') local harduino = json.decode(response) fibaro:debug('Decode: ', harduino) fibaro:debug('Or decode: ', harduino.Volt) else fibaro:debug('Not able to decode!') -- this is the executed code end --end LUA code here

Somebody noticed this arduino based z-wave board? I just ordered one for testing.... http://z-uno.z-wave.me/z-wave/interoperability-with-z-wave-controllers/

How to control Arduino nano from a VIrtual Device button?
