Added Value Logger on SD Card

[JK-de]

This optional feature writes an Excel-confom CSV to the SD card for all device values

Workflow:

• Add a SD card to the ESP (SPI...)
• In hardware-tab check "Init SPI" and set the "SD Card CS Pin"
• In tools-tab enter advanced page and enter NTP settings (for correct time stamp)
• In tools-tab enter advanced page check "SD Card Value Logger"
• In device-tab add your sensors with corresponding delay times

A file named "VALUES.CSV" is written on the SD card. It can be imported by any spread sheet program (e.g. Excel)
The file can also be downloaded in tools-tab -> "SD card" -> "VALUES.CSV"

Would it be possible initiate export using command?

[Grovkillen]

And maybe use systime and date in the file name?

i'm missing error checking in case the write fails when the sd card is full for example. (or broken)

@Grovkillen - You can already download file with http://<yourIP>/VALUES.CSV

@Grovkillen - At first I used a filename with date but then I see that the SD-lib supports only 8.3-filenames

1 Great (the download link), is it written to constantly or just on request?

2 I understand the file name now when you explain that. I will inform about this on wiki.

Would be great to be able to setup it in a way as local temporary spool no ?? all my ESP modules are connected to MBTT broker. If connection goes down (wifi dead, network issues, mqtt broker unavalaible), then it stores all local values in file. Once connection is back, it sends all spool file values stored to broker and continues to update in live time till connection goes down again and so on :)

this would be a nice feature indeed, but requires a bit of planning. maybe in a future release?

[Grovkillen]

Should we make a "future release" milestone for good ideas that are a bit longer into the future. These can then be merged in to a proper vX.Y.Z milestone once it is planned to be implemented?

[psy0rz]

that sounds like a good idea, will do that.

How do I enable this in ESPEasy-mega-20191028? I have an SD connected up to NodeMCU SPI but the "SD Card Value Logger" is not available (not even visible). Any help would be greatly appreciated.
