If you have a PWS that connects to your home network using an ethernet cable then click here.It is this "man-in-the-middle" device that will look for information heading from the PWS toward the WU cloud and redirect that information to the local Weather Service.įor more information on configuring a Raspberry Pi Zero W to act as a "Man In The Middle" solution follow these links: To do this intercepting, you place a physical device - such as a Raspberry Pi - in-between the PWS and the home network. For these PWS, it is possible to physically intercept the data stream heading to the WU cloud and redirect it to the Weather Service server instead. Many PWS already support the Weather Underground format and can be connected to the user's home network to send data directly to the WU cloud service. If available, the user documentation for the PWS should detail how to configure a custom GET request.įor more information on the RESTfull protocol click hereĢ ) Networked PWS that support Weather Underground For example, the MeteoBridge Pro allows for requests to be specified in a custom template that translates the PWS weather values and units into a format that the local Weather Service can accept. Some PWS allow the user to specify a GET request to send weather observations onto a local service for processing. The weather data can then be used by the Weather Service to calculate Zimmerman based watering levels. If you are running a local instance of the Weather Service then you may be able to send the data directly from your PWS to the Weather Service avoiding any "cloud" based services. ![]() You will need a 24x7 "always on" machine to host the service (this can be a Windows or Linux machine or even a Raspberry Pi device) provided it supports the Node.js environment.įor detailed instructions on setup and configuration of a local Weather Service running on a Raspberry Pi then click hereĬonnecting a Personal Weather Station to a Local Weather Service If you would like to choose between different Weather Providers (currently OpenWeatherMap and DarkSky are supported) or use your local PWS to provide the weather information used by OpenSprinkler then you can install and configure the Weather Service on a device within your own local network. Currently, only two exists for weather adjustment and logging a PWS observation. Routes/*.js contains all the endpoints for the API service. Server.js is the primary file launching the API daemon. The script is written in Javascript for Node.JS. The production version runs on Amazon Elastic Beanstalk (AWS EB) and therefore this package is tailored to be zipped and uploaded to AWS EB. It also provides timezone information based on user location along with other local information (sunrise, sunset, daylights saving time, etc). We often use them interchangeable depending on what we have in stock.This script is used by OpenSprinkler Unified Firmware to update the water level of the device. So a lot of common diodes can fit there: S1B, S1D, M2, M7, 1N4002. For example, D1 on OSPi is a standard rectifier with a minimum of 100V reverse voltage stand. Many rectifier diodes are interchangeable. The marking may differ somehow depending on the manufacturer, but in general the marking is not the full part number because there is not enough space to put the entire part number. For example, HC595 generally means it’s 74HC595 shift register. Markings on parts are often just part of the part number. You can even solder through-hole components onto surface mount pads, and this is perfectly fine for prototypes. ![]() For example, 32.768kHz crystals come in many different form factors, and they are mostly interchangeable. Some of your other questions really just require some familiarity in electronics. Also, I just simply forget to write them down. It’s hard to document all detailed changes partly because they are small changes that I am not sure if they are worth documenting. For that reason, the fuse is now replaced by a small resistor, which still provides the connection but will not trip if RPi starts to draw a lot of current. It replaces the fuse that was on OSPi 1.42+ because many users have started using RPi 3 which draws a significant amount of current that often triggers the PTC fuse. The resistor 3R3 is a 3.3 ohm power resistor. The difference is very minor (I believe the main difference is added PCB spark gaps at the back of the circuit board, and the components remain the same). The published files in Github is OSPi 1.42+ and the current version we sell is OSPi 1.43+.
