Hi Ray,

Thank you.

In the OSPi the 5V dc is only used to power up the PI? Not used in another “option” ?

If not i can cut the power pin oof the Raspeberry PI…

Hi,

Im working in big project too. My goal is to have an OSPi and 11 extension boards. Each extension board is 50 m from each other, with an distance of 550 m

I allready tested at the midle of the distance and i noticed that i have signal to extension boards but is not enought to turn on the valves.

With the FTP cable that i use to connect each extension board i use 2.5 mm power cable for 24V AC.

This power came from the same power supply.

So if i connect the 3x GND from FTP cable to GND at 2.5 mm power cable (24V AC), in this way the valves work fine. Tested with 1x extension board at 300 m from OSPi.

But now i having some trouble, when i try to connect the 5x extension board there is no answer from OSPi.

My question: using the interval program is there any limitation of extension boards? We need to change the code?

Hi,

Thanks for the repply,

When i change the MAX_EXT_BOARDS macro define in defines.h from 3 to 4 the Opensprinkler reboot from time to time. If i put 5 it reboot faster, and so on.

Hi,

First thanks to all that spend time to this app.

I made the upgrade and still have the related problem, only solved with new install.

But i found another issue, when we have Master Station the programs at program preview only apear once, do not repeat. If i remove the Master Station it repeat with the Every time option.

Best Regards
