Weather adjustment is non functional on Pi v2

[Sean]

• I have tried everything that I can think of to get the weather adjustment working to no avail.

When it is turned on, no wattering occurs at all. The weather diag always says 0%.

Its network connection to the Internet is good because I can successfully do apt-get commands via remote ssh.

The only way wattering occurs is if I desable weather adjustment on the program settings.

App version = 1.4.0, Harware = OSPi, Firmware = 2.1.3

My Raspberry Pi is version 2. This may be important as I may be one of only a few that are running this on a Pi V2.

I have…

• Wiped and reinstalled OpenSprinkler
• changed the location to a differant personal weather station, the local airport station and my zip code.

Here is my program export.

First, did you select to use Zimmerman method for weather adjustment? From your configuration files, the ‘uwt’ option is 0, which means it’s set to use manual adjustment.

Second, I tried your location (zip code 80538) and as of today the watering adjustment is indeed 0%. You have an average of 50% humidity, and your temperature is 48 F. According to Zimmerman’s algorithm, the watering percentage is 0. So I guess today’s weather is not a good test case.

Given that your temperature is quite low these days, the watering percentage is probably coming out to be 0 anyways. For testing, I suggest 1) change the weather adjustment to use Zimmerman method; 2) change your location to Sydney,Australia. See if this will result in a non-zero watering percentage.

Now I feel really ,really silly.

The program dump showed manual. Becaus that is how I left it after I had come to the false conclusion that weather control was broken.

I set it to Phoenix, Az (because I couldn’t figure out how to set Sydney AU) and golly gee, look at that. The % watering changed to 80%.

Face, meet egg.

 

so my lesson this evening. Is that I need to chill, have a beer and trust the the program.

ok I’ve had my beer.  Better.

 

thanks

Well, I guess you are right — sometimes you’ve just got to trust the algorithm 🙂 To be fair, the algorithm is a pretty simple, heuristics-based one. For example — it uses the average temperature, which in your case is pretty low. But your highest temperature during the day may be quite high, and you would be wondering why it doesn’t decide to water during the day. Well, all I can say is it’s after all not a real gardner, so it can’t make very intelligent decisions. But hopefully the ups and downs will be averaged out, so that it does the right thing over time.
