![]() This has worked fairly well for 3-4 years. Then I manually run a script which adjusts the fudge factor so that watering will occur the next available time. This might result in a week and a half of no watering, and I start to notice the grass withering. Every now and then, after a very heavy rain, the Sprinkler_Moisture_ Balance will be too high, because most of the rain ran off and was not absorbed by the soil. If that expression evaluates to TRUE it runs the sprinklers. At sunset, midnight, and 5 AM Indigo runs a script to check (Sprinkler_Moisture_Balance 35F) ^ (10MIN_AVG_Windspeed < 5 mph) ^ NOT Sprinklers_Running. It is equal to (yearly rain + yearly watering) - yearly evapotranspiration - a fudge factor. I maintain a variable in Indigo called "Sprinkler_Moisture_Balance". I use the Davis to control my sprinklers as follows: First, I have determined, over several years, that one run of my sprinkler system is equivalent to about 0.33" of rain. They tell me, for example, that although it snowed last night, the soil temperature is still ~60F, so I can leave my sprinklers on. The associated soil temperature sensors work fine. Currently their readings are as follows: 170, 56, 200. I've had 2 of them read near zero while the third reads in the 100-200 range (out of 255). The data don't change consistently after a rain or a lawn watering. ![]() They deliver inconsistent and useless data. They are in a line about 10 feet apart 6"-8" deep in my front lawn. I installed 3 of them from Davis a few years ago. You WILL need to have a basic understanding of scripting if you want to log the weather info, but it's less than half the price of the Davis for the basic wind/rain/temp/humidity sensor suite, and OSI compatible Radio Shack temperature senders are under 20 bucks a pop, although I haven't actually tried using the waterproof ones on a long term basis the one I use to monitor the bbq pit meat temprerature works great to let us know when the brisket is done, but not well done.(triggers are a wonderful thing ) However, (short term) I have been impressed with the RFX/OSI package I set up from Homeseer (and now available from SimpleHome, I hear) two months ago. I plan to pull it down, disassemble and waterproof it with vasoline next time the CR123 battery dies (about a once in 18 month maintanance procedure, even with the solar panel). I think it's because of the design of the connector they use, which can get shorted out when it's damp. I've had the VantageVue (the all in 1 wind/rain/temp station that uses the Vantage Pro console, which means it could accept the additional sensors) for nearly 4 years, and it is a pretty rugged unit however, I do have an issue with the rain sender every once in a while it simply quits counting in the middle of a rainstorm. I would be open to suggestions of weather (pun intended) to use the Scientific Oregon sensors and the RFXCOM, or to go for the Davis. The system would be used with Weather Snoop or perhaps WeatherCat with Indigo / Security Spy. I plan on having a external temp sensor in my fish pond. I have been researching the same thing, seems like the Davis Vantage Pro2 is the unit to get, although pricey, it seems (from the reviews) to be the most robust & offer the most features / options of any weather station in the sub $1k price range. I would love to hear about everyone's set-ups. models w/ best reliability in extreme heat īasically, what do I need to know to move forward in buying a station. Rainfall is not important since we don't get any! Sounds like there is no need for WS until I get my own station. Great! I have data on port 8000 Thanks Jay
