Smart Hose Watering Timer. This is the best timer I have used. I can use it from inside the house when connected to bluetooth. As an example, if it starts raining, I can go to the app and put it on rain delay from my bed.

There are 3 different versions with 1,2 or 4 ports. Additional ports are for watering different sections at different times, days and different durations. I have mine set up for my vegetable garden, bushes, and trees. Each of these need a different watering schedule. You could even schedule one to water your grass.

You set up different watering programs and you can change and adjust the programs or add a multitude of programs so you only have to select a different program.

Examples for Vegetable garden watering programs you can set:

1 - Seed starting in garden. To keep the seeds moist you will need to water for a couple minutes several times a day until the seeds sprout.

2 - Spring/Fall watering

Water every other day

3 - Summer temps in mid 100s

Water daily

4 - Summer temps 110 and higher

I change the frequency to 2 times a day

5 - Winter watering

Water every 2 days
