Video of the functional test with 8 solenoid valves (Rainbird 100-HV-MM 1″ 24 VAC):

Note: “Up to 8” as other solenoid valves from other manufacturers may have different performance specifications. Especially with the OSPi, the power supply also has to supply the Raspberry Pi, which further costs power. This information is therefore to be understood as a guideline value.

But the OpenSprinkler Ethernet adapter also needs power, which means there are “only” 7 left.

Cable lengths > 10m or with a small cross-section also dampen the performance.

The power supply is specified as 24VAC 1500mA. During my test I was able to measure a voltage of 23.9V at 1580mA. The power supply was just lukewarm even after 15 minutes of continuous load. By the way, only the solenoid valves “hum”, but not the power supply!

Further note: The power supply is like the OpenSprinkler not waterproof.
