@ian Belated thanks for your comments. Did you ever get an answer to your question “If anyone can point to instructions on how to “run a script that periodically sends command to OpenSprinkler” I’d be grateful.” in your reply to me above?

I see and understand the syntax HTTP GET command for changing the percentage. My question is, how do you actually send this command to the firmware to affect a change. I’d like to park such a command in a cron job(s) to send a percentage update at various times of year. But, what is the sytax in the cron job OUTSIDE of the command itself. EG, it seems like a URL is needed, maybe aport. Perhaps there needs to be a command to set a temp userid.

Thanks.

…. Note. a while back suggested I’d somehow use the HTTP GET command, but I’m not sure how.

Hi Franz. I’m glad you got the API call working.

I’d like to ask you how you make the API call. What I’d like to do is call the API 3 or 4 times a year via, say, a cron job, to change the water % setting according to the season. I’m somewhat familiar with making cron jobs, but I’m not sure how I’d create the file (that the cron job would run) that calls the API.

Thanks in advance

Hi. I just found this thread. Thanks for the information.

I’m wondering: Aside from the “evapotranspirational” calculations and weather prediction approaches, are there not solutions that rely on using moisture detectors placed in various parts of a garden to determine if watering is needed or not? If you recommend this approach for some situations, and also recommend particular hardware, I’d be interested in your comments.

It seems to me that direct moisture measurement (eg via say a device calibrated to measure electrical resistance in the soil) would be quite effective in stopping or reducing sprinkler activity during the a rainy period.

Thanks in advance.

Thanks Mike. Apart from my ideas for a DIY pressure sensor, do you know of any inexpensive (under $10) commercial pressure sensors that will flip a switch when the circuit pressure goes above or below a preset amount?
