So, I have successfully been running TIG to collect some climate data from Tasmota devices. All has been good. Running Telegraf 1.13.2-1 on Ubuntu
Said Tasmota devices sends data in the following form
{
"Time" : "2020-01-27T06:38:05",
"AM2301" : {
"Temperature" : 17.7,
"Humidity" : 51.3
},
"TempUnit" : "C"
}
The publish to the topic “tele/+/SENSOR”, and i see good stuff in my database
> show series on telegraf

1562523952000000000 93 13.1 server01 tele/Klimatsensor_Street01Lagt/SENSOR
Soo, i thought i would be clever and use the same database for a NON tasmota sensor, which published messages in the form of
{
"Time" : "2020-01-27T06:40:10",
"SEN0232" : {
"SoundLevel" : 47.14285714
},
"SoundLevelUnit" : "dBA"
}
to the topic dBA/Dansgolv
To me, these seem pretty much the same as the ones from Tasmota. But they do not make it into the database for some reason that baffels me. I thought i would see SEN0232_SoundLevel in my database. But no…
At the bottom of this post is my telegraf config before adding the new sensors. After adding the new sensors i changed my topics, and restarted telegraf.
I feel I must be missing something very silly, and very fundamental… But what?

After adding the new sensors. my topics are as follows. (Again, i DID restart telegraf after making the change)
topics = [
"tele/+/SENSOR",
"dBA/Dansgolv"
]
