Here’s my take on OpenHAB Irrigation Automation. I’ve tweaked the Spilota approach of referencing recent past & predicted weather. To that I added final control based on the reading of a home made soil moisture sensor (instead of various timers)
My version uses a Gateway <-> Node approach, but probably could be adapted to an ESP8266 wifi node. See this thread about using & calibrating the soil moisture sensor node. See this thread about irrigation automation that uses the weather data AND the soil moisture sensor node.
I tried to set up your way of doing irrigation control with openhab. But I have some difficulties.
I can successfully control the ESP8266 manually with the buttons on the sitemap you have on github.
But with the irrigation program it doesn’t work. I think there is a problem with the irrigation.rules.
First of all I always had an error in the log which was saying:
2018-10-30 22:12:36.523 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Rule ‘ScheduleProgramA’: The name ‘sendTweet’ cannot be resolved to an item or type; line 203, column 3, length 96
I got rid of that by commenting the sendTweet in the irrigation.rules file with // out.
But it still doesn’t work. In the log I can find:
