SolVecConMon

Read full description

SolVecConMon stands for Solar Power and Vehicle Control/Monitoring. Have all important solar and loadpoint values on your Apple Watch with a finger tip - IN REAL TIME. With the appropriate evcc server setup - see below - direct, worldwide access is possible - the most exciting use case. It is a watchOS app that has a Companion iOS app, but can be installed and run independently of the Companion App. SolVecConMon is configured in the watchOS app as well as in the iPhone - depending on use. Up to and including version 2.0 it was purely a watchOS app. From version 2.1 on there is also a companion app - because with IOS17 and visonOS a Companion app will bring advantages in the future. However, the focus is still on the watchOS app. Please note! • For a first Look&Feel impression it's enough to download the App - it automatically connects to the cloud based evcc Demo System - https://evcc.io. • Prerequisite for real operation is to have a locally installed Solar Charging evcc System (at least Version v0.301.1) - https://evcc.io - SolVecConMon is powered by evcc! • App access outside of the local network requires additional software components. For the RaspberryPi 4, an image is available for download at https://jfraundo251158.github.io, which contains all software components preconfigured and thus significantly simplifies the system setup. Good to know! • App updates after the first App download are done in the Apple Watch. Please search for solvecconmon in the Apple Watch App Store and click the download-cloud. • It's much easier to edit the Apple Watch App Store and App Configuration tab fields through your iPhone/iPad. For this please take care that in the iPhone/iPad Settings for Apple Watch Keyboard - Allow Notifications - is set. Track IN REAL TIME • solor power generation • house consumption • house batterie charging/discharging • Vehicle(loadpoint) monitoring • Vehicle(loadpoint) charge mode control This version supports • one solor grid - mandatory • one house battery - optional • 1st loadpoint - mandatory • 2nd loadpoint - optional (after selection "Number of loadpoints: 2" the App or Apple Watch restart is necessary to make it effective) • Complications (Watch face externsions) - optional Proven data exchange with evcc - versions • v0.307.2, v0.307.0, v0.306.3, v0.301.1 The application is working in your local network with running a local installation of https://evcc.io. For that you need to enter your evcc installation server in the App's Configuration tab like http://mymachine:7070 or http://myIP:7070 (expected you are using the default evcc port 7070). If you want the App having access outside your local network you need additionally setup an 'Edge Router' (reverse proxy), which provides basic authentification feature and https secure connection. A detailed instruction guide along with an RaspberryPi 4 Image for download is to be found on https://jfraundo251158.github.io. SolVecConMon is in operation on below Server setup. Hardware: RaspberryPi 4 (LAN connected) Software: • Image/Container Management Docker - https://docs.docker.com - open source • Solar Charging evcc container - https://evcc.io - open source • Edge Router Traefik proxy - https://doc.traefik.io - open source • Let's Encrypt - https://letsencrypt.org - a nonprofit Certificate Authority With that SolVecConMon is additionally powered by Raspberry, Docker, Traefik and Let's Encrypt.

Solar Planner

Features
Read full description

App to calculate the solar production. The app calculates the reduced solar earnings compared to an optimal panel position. Two factors reduce the real solar earnings: 1. The direction and the tilt angle of the solar panel. 2. The shadowing due to buildings or trees. The yellow area in the picture shows the possible positions of the sun during the year. The brown area represents the ground to the horizon. Using augmented reality the shadowing is drawn directly on the screen by repainting the buildings or trees. The direction and the tilt angle of the solar panel are set by using the direction and tilt angle of the iPhone/iPad. Either by holding the iPhone/iPad in the direction of the sun. Or by laying the iPhone/iPad on the solar panel. (The tilt angle can be 90° at maximum.) The result of the calculation shows the solar earnings compared to the highest possible solar earning in percent. The solar earnings are also shown in a year diagram and a day diagram. The Calculations can be used for photovoltaic and solar heating systems. Used methodology: For every time during the year the position of the sun at the sky depending on the geographic location is calculated. The solarisation on the panel is calculated by taking into account the panel direction and the panel tilt angle. The solarization is summed up for all times without shadowing. The calculated solar earning of the calculated panel position is shown compared to the maximal possible solar earning in percent.
