Hi there
I’m starting from scratch so there’s no need to integrate into an existing setup.
I’d love to power the OS3 from solar but am trying to decide:
A) latching or ‘regular’ DC solenoids (are there significant advantages one over the other, particularly with my solar preference in mind?) The attached (latching) has some appeal but a more modular standard setup would perhaps be more flexible?
B) whether anyone can advise on battery type/capacity and necessary solar panel/controller for either/both latching and standard valves.
Attachments:
The best option is probably OpenSprinkler 3.0 Latch, which operates latching solenoid valves. Due to WiFi, it still draws a fair amount of current (like 100 to 200mA) so it’s not meant for battery operation without any re-charging settings. However, if you have a solar charged battery it should be feasible.
The other option is OS Bee, which is a smaller controller also for latching valves — it operates only 3 zones so is good for small-size projects.
