Just this morning, I was reading mail from SoCal Edison about rebates for having a Water-Based Irrigation Controller and I thought to myself, “too bad I bought my opensprinkler so long ago, I missed out on a rebate!” And then looked further and found the EPA list.
I will be converting my front yard into a drought tolerant landscape and will be applying for a rebate through my city for the work. In order to qualify for the rebate, my city (Sacramento, CA) is requiring applicants to use EPA WaterSense controllers. So this will effectively require me to retire my OSPi. Glad you’re on it. Hope it pulls through.
It looks like OpenSprinkler still isn’t on the EPA WaterSense list. I contacted the WaterSense department and asked if there is anything we can do to get OS added although I haven’t received a reply yet. Does anyone know what needs to be done to get OS EPA WaterSense approved?
According to our readings of the WaterSense documents, it seems implementing ET is necessary. We do have an initial ET implementation in the opensprinkler-weather github repository. We are doing some final testing right now and hoping to release it as soon as possible.
On a related note, I still don’t quite understand how some of the ‘dumb’ (i.e. none Internet connected) controllers are WaterSense certified, maybe they use just historic ET data without real-time weather data. Any ideas?
