### Conclusion ### Conclusion
This was a fun little staycation project that I'm certain has great expandability. Next year once the garden is arranged I'll probably start work on a larger, multi-zone version to better support the huge garden. But for today I love knowing that my hose will turn itself on and water the garden every night if it needs it, no involvement from me! I hope you find this useful to you, and of course, I'm open to suggestions for improvement or questions - just send me an email!

### Errata
*2018-10-03*: I realized that 4.0mm of rain as an automation value was quite high. Even over a few days of light rain, it never reported above 1.0mm at any single ~2h interval, let alone 4.0mm. So 0.5mm seems like a much nicer value than 4.0mm for the "it's just lightly showered"/"it's actually rained" distinction I was going for. The code and descriptions above have been updated. One could also modify the templates to add up the 24h/48h total and base the condition off the total, which is a little more clunky but would be more accurate if that matters in your usecase.
