Automatic Freeze damage protection

I have a product improvement request.

We had more than two weeks without frost at night and very dry and sunny days. So I started the irrigation system last week.
Now we have two nights with temperatures [at 5am] around freezing and a little below by [7am].

If temperatures are that low and since I use sprinkler heads with check valve, it would be a desired feature that my Rachio 3 waters all lines for 1 minute every 30 min once it is as low as zero degrees. Currently I got to set this up manually and 1 minute is more than what is needed.

If I could tell my Rachio3 which line’s how long, it could water the lines, just as much as needed to replace the freezing cold water with warmer water from the well or house.

Who’s in support of this feature???
