One group not displaying

I have been gtrying to group my sensors by function, but so far I can’t seem to create a Humidity Sensors group. My groups.yaml file doesn’t show ant errors, and all the other groups work fine except for the humidity one. Anyone have ideas on what I’m doing wrong?:

Well, to answer my own question it seems HA didn’t like the name humidity_sensors_group. I renamed it and all is well now.

For next time you have a problem, you will need to format your text/code, as per the blue box at the top of this and every page.

Hi @Cee, I thought I had used fences, but I obviously did it wrong! Thanks.
