Trying to change units in WeeWx-MQTT not completely successful

[L B]

I have been using Weewx for some years, and decided to export data to MQTT to put into HomeAssistant. It has been successful on Weewx version = 4.10.2 from Debian with Matthew Wall's MQTT extension.

I have been following some instructions from a 2018 thread https://groups.google.com/g/weewx-user/c/MkP6Tacef7k and have managed to change units for rain on the MQTT extension but not for rainRate.

When I had rainRate set for mm_per_hour Weewx refused to start.

log excerpt for one cycle which was successful and the next try with mm_per_hour in the config is attached

offending part of weewx.conf also attached. Commenting out the three lines allows weewx to run

The 2018 post describes success with using mm_per_hour for rain rate. The designation seems to be a current unit in https://weewx.com/docs/5.0/reference/units/

Can anyone help me to get mm_per_hour not cm_per_hour outputted by mqtt?

Liz,

The log points to a config read error. Looking at what you posted, seems you have a fourth bracket missing after rainRate.

Thanks for that. Weewx has started, now to wait to see if the edit is successful.
