A wifi sprinkler controller could be rigged to do this. I've used https://rachio.com/ for a few years and it has worked well from anywhere on the planet. Source: about 1 year ago

I would highly recommend getting a Rachio smart sprinkler controller. It will automatically adjust watering based on weather, sprinkler type, grass type, etc. Source: about 1 year ago

There is a rental we are moving into. I noticed in the garage, it appears to have an active internet modem. It also has a Rachio smart sprinkler system, so it might just be set up for that. But it also has a Ring Doorbell camera. Source: over 1 year ago

If you don't already have a 'smart' controller for your system, I can't say enough good things about a Rachio controller. I think mine paid for itself after a year . . . It looks at the weather patterns and won't run if rain is in the forecast. During times like this, you can 'fine tune' so it runs more often. (I don't f with mine - it runs the same program all year). Source: almost 2 years ago

You could definitely outsource this math to a smart sprinkler controller. I’m also in Massachusetts, 6b, and I use a Rachio - it’s done a very good job of scaling the water amount up as the weather has warmed up, and pulls the local weather data to run its calculations with.

Maybe it's on the internet connection, try Facebook Lite and it should work. Source: over 1 year ago
