Log data to clouds
Remote logging can be used to post data to a HTTP server that BrewPiLess can connect to.The format field in log setup page is like the format in printf but uses the following specifiers:
| Specifier | output |
|---|---|
| %b | Beer temperature |
| %B | Beer setting |
| %f | fridge temperature |
| %F | fridge setting |
| %r | room temperature |
| %g | gravity |
| %t | tilt value from iSpindel |
| %a | auxiliary temperature |
| %v | external device voltage |
| %u | UNIX timestamp of last gravity update |
For example, let beer setting be 20.0 and beer temperature be 18.3, if the format is api_key=TheRealApiKeyHere&field1=%B&field2=%b,
the data will be api_key=TheRealApiKeyHere&field1=20.0&field2=18.3.
If the method is GET, the data will append to the url with additional ?, so the result will be
http://api.thingspeak.com/update?api_key=TheRealApiKeyHere&field1=20.0&field2=18.3.
(GET is usually not recommended.)
The Data Type field is used as "Content-Type" in HTTP protocol. When it is left blank, the default value of application/x-www-form-urlencoded will be used. The default type is good for content like A=V1&B=V2.
Example setting for Thingspeak.com
Example setting for ubidots.com
Due to the memory limitation, HTTPS is not supported. Therefore, if you want to send data to a service that supports only HTTPS, an additional proxy is needed.
