    Direct to Excel Measurement

    Dear AndreF85:I have repeated the steps and observed the following errata:- The web server defined by the program "Temper.lua" uses only cell A1, so it must be the range defined in the querry and in the reference of D1.- since the server writes a single line, the text that is received in A1 must be parsed by the function = VALUE (MID ($A$1; 6; 16); "."; ";"; 1)) And further, this formula must be defined in E1 and not in D2 as indicated. Note that this substitution is only necessary if the excel configuration uses "decimal comma" instead of "decimal point".- I observed as stated, the load of the operating system is a delicate issue since Windows is not a "Real Time OS".

Note that this substitution is only necessary if the excel configuration uses "decimal comma" instead of "decimal point".- I observed as stated, the load of the operating system is a delicate issue since Windows is not a "Real Time OS". So antivirus programs and updaters can interact negatively, causing freezes. If used within a local LAN, almost all unnecessary OS tasks can be turned off.- I have the impression that the system operates more stable with a speed of 9600 instead of 115200 as indicated. It is also difficult to read more than one sample per second.- It should be noted that the Querry function has many parameters that must be controlled.- It also seems important the LUA interpreter to be recorded on the ESP8266. In my case, I use float_0.9.6-dev_20150704.bin- Considering the above points, I could repeat the instructable from scratch so that, considering the errata, it should work well. Otherwise, please tell me more information about the programming environment of your system and if there is any message or behavior that can give indications of the reasons for malfunction.Thank you very much for your comment that motivates me to make a revised version.
