Not enough values for deriving formula
To create a formula its required to have at least 3 measurements.
Error validating created formula. Deviation to large, formula rejected
The device will try to create formulas with different complexities. It will try to validate the formula using the supplied values. If the difference is more than 1.6 SG on any point the formula will be rejected. Check the entered values if they seams to be reasonable.
No valid calibration values, please calibrate the device.
The gyro needs to be calibrated at 90 degrees (flat). This is done on the configuration page.
Low on memory, skipping push
The arduino libraries sometimes leak memory, this only occurs when running in configuration mode. To avoid crashes the device will skip pushing data if the memory drops to much. Network connections seams to be connected to memory leaks.
Unable to set header, invalid value
Check the format for your custom header. This means it has not a correct format.
Influxdb push failed response
HTTP push failed response
All these errors are standard http error codes. This are the common ones;
400 - Bad request. Probably an issue with the post format. Check format in the format editor.
401 - Unauthorized. The service needs an token or other means to authenticate the device.
403 - Forbidden. Could be an issue with token or URL.
404 - Not found. Probably a wrong URL.
In some cases there can be negative error codes which have the following meaning:
-1 - Connection refused
-2 - Send header failed
-3 - Send payload failed
-4 - Not connected
-5 - Connection lost
-6 - No stream
-7 - No HTTP server
-8 - Too little RAM available
-9 - Error encoding
-10 - Error writing to stream
-11 - Read timeout
-100 - Endpoint skipped since its SSL and the device is in gravity mode
MQTT push on <topic> failed error
-1 - Buffer to short
-2 - Overflow
-3 - Network failed connected
-4 - Network timeout
-5 - Network read failed
-6 - Network write failed
-10 - Connection denied
-11 - Failed subscription
