Chamber temp not being used to preheat chamber

I have a BME280 running as my temp sensor in my chamer. It shows up in the on the dash, but RatOS wont wait until this sensor reaches the temp I provided in the filament. I get the feeling it still relies on the hotend thermistor as a chamber sensor. I have double-checked my slicer settings against the documentation. In the how to, its not really clear to me, if I configured the cfg correctly.
1. Bed Heater By default, RatOS uses the bed heater to heat the chamber. Either the hotend thermistor or a chamber thermistor will be used to monitor the initial chamber temperature. If no temperature_sensor chamber is defined, the hotend thermistor will be used. Configuration Use these exact device names in your configuration: [temperature_sensor chamber] sensor_type: ATC Semitec 104GT-2 sensor_pin: PF4
It throws an error, if I add a pin to my cfg. At the moment my sensor part of the cfg looks like this: [temperature_sensor chamber_temp] sensor_type: BME280 i2c_address: 118 i2c_bus: i2c1a It started printing at 38.6° C even though I put 45° C in the filament config in the slicer. It even relays it to RatOS:
"RatOS: Preheating chamber to 45°C..."
Can anybody point me in the right direction?

Drop your printer.cfg in here maybe

OK, I think I figured it out: The sensor must be named "chamber", then RatOS will see it.
