Rain meter query

I have a weather station working with 1mm per bucket tip
The unit reports both total rain and mm/h

If I add a wider funnel, I can effectively decrease the mm per tip, so increase unit resolution

My query is can I then simply scale the total rain and rain rate reported via RFXComm to HA by the ratio of old tips/mm vs the new…?

Yes, you could use a template sensor to do that.

Thanks. I wasn’t sure whether if:

I add a wider capture funnel, so the mm/bucket_tip is divided by X thanks to wider tunnel
The rain rate is thus divided by the same factor, as is the total rain

I think the answer is yes

Oh sorry, I see what you mean now. Yeah as long as the rain rate period stays constant it scales with the total quantity.
