    Hi gerryr1gerryr1

    Your Power supply confuse me,and i am no guru either….

    Here are some presumptions:
    1. Power Supply is 24Vac
    i. In that case D3 will do half rectification for your load.
    ii. No power will get to your voltage regulator as D2 block the positive half that was allowed by D3.
    iii. D1 is not doing anything.
    iv. I see no power getting to your OpenSprinkler

    2. Power Supply is 24Vdc
    i. D3 does nothing and your load has 24Vdc
    ii. No power will get to your voltage regulator as D2 block the positive that was allowed by D3.
    iii. D1 is not doing anything.
    iv. I see no power getting to your OpenSprinkler

    You need to understand that the “AC” unit can not work properly on a “DC” supply as the Triacs require AC to switch off.
    If you require a “DC” to drive your load, then you need to place a AC-DC circuit on each output to drive you relays, you still have to supply the OpenSprinkler with 24Vac to make it work

    Hi Ray

    I am no software guru, but if you can point me to some examples of what i need to do and how the script work, i can see if i can get it to work on my local server.

    Hi Robert / PollieXmas

    My Open Sprinkler has been working 100% since 2013 without issues.
    I did not experience any issues where the WiFi went to sleep.

    My issue only appeared after my Raspberry Pi were unable to connect to my access point for an extended time, 07:00 to about 17:30.
    I had to reboot the RPi to get it working again, since then my RPi has been online without any issue.

    So it seems that if you lose connectivity to you AP for a extended period, the RPi does not re-connect to the AP once the AP comes back on line.

    I had similar issues before on another project and the only way i was able to fix this was to get my RPi to ping the router every 10Min.
    What i have noticed is that my unit worked 100% unit i lost wifi connection to the unit for an extended time.
    I had to switch my AP off for a day when i had work done in the room where the AP was based, from 07:00 to about 17:30

    One the AP was back online, i was unable to see OSPi, the only way to get it back on line was to power down and power up again.

    Anyone with some idea, else i shall edit cron and add my 10Min. ping

    Hi LeighGr

    I am in Duynefontein, next to Melkbosstrand.
    As you know this side of the West Coast there is only sand and it does not retain water very well and to top it all the hot summer winds will dry anything to a crisp.

    Is it possible to include the current wind speed and “inhibit” the schedules if the wind speed is above value “X”?

    Brilliant, Thank you.
    My plan is to add a DS1307 on the I2C so if there is no internet connectivity after a re-boot, the PI can still get the time from the RTC and the schedule will still work as normal.
    Power is NOT that good and reliable down there in South Africa.
    Then only thing i would like to see is to add I2C support for MCP2317. I would prefer to use the I2C I/O instead of the direct R-PI I/O.
