How to add a PIR as a device (wired)?
Hello all,
I just recently bought a PIR sensor (https://www.amazon.de/gp/product/B07CNBYRQ7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1). I am using an old Raspi (Model B Rev 2).
Does someone know how to bring it live with Pimatic? How to configure the PIR as a device etc.?
Thanks!
Before starting connecting wires on the GPIO pins of your Raspberry Pi, make sure you properly shut down the Pi and removed the power cable of the board. Connect the PIR to a Raspberry Pi. You need three wires. Connect the VCC pin of the sensor with a 5V pin, connect the OUTPUT pin of
the sensor to (for example) pin 23 (or another free GPIO-pin), connect the GND of the sensor to a GND pin. Start your pi and pimatic. Install the plugin pimatic-gpio. Add a new device, class: GpioPresence. The gpio (pin) is 23 (or another free pin you use for). Add your new item
and the magic can start.
Perfect, thanks @Alter_Knochen ! It works! Do you know by chance how to connect an Esp8266 module with a Pir, and how to make them talk with pimatic (on a raspi)?
There are a lot of ways to bring an ESP in life and to communicate with it.
For example programming with the Arduino IDE in C++ (or MicroPython ?), ESPEasy, ESPHome and so on.
I personally use the Arduino IDE and since a week I work with ESPHome (I flashed a XIAOMI Bluetooth Hygrometer with a new firmware in order to communicate with it to pimatic. After that I “programmed” a ESP32 with YAML-templates to read and to transmit the BLE-data over MQTT). All methods in common is the use of wifi and MQTT. There are tutorials about programming a ESP8266 with the Arduino IDE in the web. Look for sourcecode about wifi, mqtt and pir.
In this case a fast method without programming is the use of ESPHome (cut & paste). I like it! Check out this short tutorial with good examples:

To integrate your smart PIR in pimatic you have to install a MQTT-broker (Mosquitto) on your raspi and after that you have to install the plugin
"mqtt" in pimatic (settings: host-IP, port). Create a new device, class MqttPresenceSensor. Fill in your chosen topic for your PIR, click at “onMessage”, type “true”, click at “offMessage”, type “off”. Create this item.
Adding Wired Motion Detectors to the Vista 20P These devices typically use passive infrared (PIR) technology to detect motion.
@alter_knochen thanks again. Interesting. So far I was also using Arduino IDE, but ESPHome looks like a good alternative with good documentation.
Mosquitto already runs on my NAS, as well as my main Pimatic instance (via Docker).
I will give it a try!
