![]() Note: You do not need an X desktop environment for this project as the software draws directly to the screen's frame buffer. In my case, I ended up installing the latest version of Raspbian Jessie Lite and followed these instructions to get the display working. Adafruit does provide a nice guide and pre-baked OS image which includes these however, this older image does not work properly with the Pi Zero W (wifi is completely broken). The PiTFT display requires special kernel drivers, configuration, and calibration. To add the alarm to Home Assistant, simply drop this into your file: configuration.yml alarm_control_panel:Ī full list of configuration options can be found on the alarm.manual_mqtt documentation page. This relies on having the MQTT platform up-and-running, so make sure you do that first. Home Assistant v0.50 adds the new alarm.manual_mqtt component we'll need to use. Simply connect the PIR sensor to the extra pins on the underside of the display - see the Motion Sensor section further down this page. By adding a PIR motion sensor we can have the screen stay off until someone approaches the keypad, thus prolonging the life of the display. Optional: The software also supports an optional screensaver mode where the screen blacks out after so much time. *I used a Pi Zero W for this project, but any Pi with wifi should work (even one using a USB wifi adapter). PiTFT Plus 480x320 3.5" TFT+Touchscreen display from Adafruit.In my case, I chose to build a solution using a Raspberry Pi with a touchscreen.Īt a minimum, you'll need the following components: I therefore created the new Manual MQTT Alarm component which functions identically to the manual alarm, but also allows two-way communication over MQTT! With this component we can easily build our own remote keypad using any web-connected platform we can imagine. The manual alarm unfortunately doesn't have a single API interface we can use to send arm/disarm commands while also receiving instant state changes from HA. While this works fine, the only way to arm/disarm the device is through the web interface. Eventually I'll be expanding this to include motion sensors and a siren. If any door opens while the alarm is active, I receive instant push notifications on my phone and computers. In my case, I have several Z-Wave door sensors on all of my exterior doors. You can then use various sensors to determine if/when to trigger an alarm. Among its many features is the ability to implement your own home security alarm system. Home Assistant is an amazing open-source home automation platform. It was a Pi 3b.This guide walks you through the creation of the project and provides everything you need to create your own! I bought mine direct from SA, it was just easier as it was my first Pi and I wanted to shorten the learning curve. There is no time frame for this feature.ģ. Having SA monitor more than one source of battery data is an oft requested feature and is on the long list of features to add. But if you are hoping to connect each battery BMS individually to the SA Pi then at present SA cannot do that. So if your battery's BMSs are connected to each other and one acts as the main comms connection to the SA Pi then yes it can report on each battery, provided it is a compatible BMS/comms. ![]() SA, at present (it may change in future), can only monitor one source of battery data, be that a BMS or a shunt or via an inverter. So now I have it connected with an ethernet data cable. Where I've had trouble is my sometimes flakey local WiFi. It's about as reliable as your power supply and internet and local network connections. I need something that is reliably going to work for the 6 months I am away.ġ) Is SA and Pi a reliable solution for remote monitoring/control?Ģ) Can SA monitor 2 inverters and 3 BMS all at the same time (Doesn't the PI only have 2 USB input ports, wouldn't I need like 5?)ģ) What version Raspberry PI should I get or should I consider the Orange Pi which it appears is what SA is using for its pre bundled package?Ĭlick to expand.1. I have also read about problems with SA/Raspberry PI crashing and needing rebooting, etc. I have read that Solar Assistant now supports Growatt SPF inverters and Daly BMS. I have been using Growatt ShineServer cloud/web based monitoring, which has worked without problem the last couple of years but because my batteries do not communicate with the Growatt inverters I am not able to monitor individual battery /cell voltages or SOC. This set up is for an off grid vacation home where I am gone 1/2 the year. ![]() I have 2 Growatt SPF 3000TL LVM (in parallel) connected to 3 280AH LiFePO4 battery banks (also in parallel) each with a separate Daly BMS. ![]()
