Updated to BETA. Same issue
As for the change in error message to POST. I did try various things (removing tag-keys, changing names, changing to BETA and changing back). I believe the change from “query failed” to “post failed” happened when I changed the measurement name to “test” as a test. After changing it back the new “post failed” remained.
So interestingly. As I mentioned the error occurred at 20:48. After looking at the log, that was when the IotaWatt unit did a six week routine restart. After this reboot it was no longer working.
12/07/21 01:34:14 Updater: update tables from invalid to 0.0.4
12/29/21 20:48:16 timeSync: Six week routine restart.
