Smart Van Features

Intranet:
I have set up a webserver and hotspot on a Raspberry Pi 3B. There is a MySQL database accessed through phpMyAdmin. Data in the database is submitted and retrieved using php. This intranet (not hooked up to internet) can be accessed from Smartphones and computers in the Van. I have used chart.js for some pretty impressive graphs. Here is what the homepage looks like without a connection to the database:

Recording of Electrical Data from Battery Monitor and Charge Controller:
I have 2 Victron VE.Direct to USB serial interfaces to the Raspberry Pi which submit data from the Battery Monitor and the Charge Controller. The information from the Victron battery monitor and Charge Controller as well as some calculated and estimated values can be seen the the following sample pages:

Environmental Values:
I have Wemos D1 Mini ESP8266's (this has built in WiFi to send results to the Raspberry Pi database) recording environmental values. A BME680 measures inside barometric pressure, temperature, and volatile gas. The BME680 can be used to approximate the altitude. If the actual altitude is entered it will give the barometric pressure. An AM2302 temperature and humidity sensor monitors the garage. A BMP280 supplies the outside temperature. The results can be seen on the Intranet Homepage.

Control of 3 way Lights:
A relay and an ESP8266-01 are used as part of 3 way switches with the wall switch to toggle the light switches from smartphone/computer. This is what the interface looks like:

Vent Fan can be Controlled by Temperature:
This feature is built into the MaxxAir MaxxFan.
