We currently only have an OSBee Shield for Arduino. Within the US, 24 VAC valves are still pretty standard and common to find, so the 24 VAC version of OpenSprinkler will still be our main product. DC latching solenoids (which is what OSBee is designed for) are most suited in battery-powered controllers. But because our focus is on web-based controllers, which are pretty power hungry, they have to be powered from a wall adapter and batteries won’t be sufficient. This defeats the purpose of choosing latching solenoid valves. So unless if you can’t source 24 VAC valves (which may be the case for International markets), there is no strong reason to use latching solenoid valves.
In watering system for private use, Gardena is the most common brand in Sweden. The sprinkler valve is 24 V AC. I have 5 of those in my garden, wired of course.
The benefit with RF controlled DC valves is that I don,t need to prepare cables. So infact these could be used for watering temporary flowers, shrubs? during summertime, standing in pots at the terrace. Those pots are movable during season. When leaving for holiday or visit summer cottage the small amount of soil gets dry very fast.
Water connections I have several around the garden so then I can just connect a hose with “drip holes at each pot.
By the way, the input on OS i use for checking if lawn robot is at home for charging with a micro switch. When we’re not at home I then have control if it’s got stock somewere, over a longer period. Nice with friendly neighbours that can help you with just a call. I also use a output on OS to latch a relay so I can switch between 2 different inlet. Micro switch for robot or rain sensor.
