Pete's Blog HOW LIGHTNING WORKS and use of automation methodologies

[pete_c]

Here since the 1990's always fascinated with Lightning. Used a 1-Wire lightning sensor back then with Homeseer 1. (late 1990's - early 2000's) Still have the sensor and it still works fine.

LD3-R2 Lightning Detector - How it works

connected to a Mideon Temp05/08

This blog is about Lightning and what sensors I use today. Last night had a storm pass through. Using text to speech notifications today for local lightning.

First a video called HOW LIGHTNING WORKS - Weird World of Lightning

Sometime in the 2000's found Blitzortung.org

Live Lightning

For Homeseer at the time used a custom PHP page to view lightning on my touchscreens.

Will post it here when I find it.

Fast forward now to a post from Homeseer:

AS3935 Lightning Detector Sensor to MQTT - 2020 Version
September 9, 2020, 04:56 AM

This is a revisit of an old project that used an RPi a few years back.

Orginally tried to do this with Buster 64bit on the Pine64. Didn't work probably cuz the Buster 64bit libraries do not match or do not exist yet to the 32bit Buster libraries. When I used the 32 bit Buster on the RPi all worked well.

Trying this two ways. One is to connect to an RPI and the other is to use a XXX and Tasmota firmware.

Hardware and mod adds utilized:

1 - Rpi 2 with Buster 32 bit
2 - enable i2C via rasbi-config
3 - sudo apt install git python3 python3-pip python3-pigpio pigpio
4 - sudo git clone https://github.com/ironsheep/lightni...MQTT2HA-Daemon /opt/ISP-lightning-mqtt-daemon
5 - cd /opt/ISP-lightning-mqtt-daemon
6 - sudo pip3 install -r requirements.txt

2 - GY-AS3935 AS3935 Lightning Detector Sensor Thunder Storm Warning Distance Detection Module for Arduino Raspberry Pi Weather Station（Max 40km）- Amazon

Pins from Lightning detector module to RPI



AS3935 Lightning Detector Sensor to RPi wiring

This wiring part to the AS3935 Lightning sensor is missing in the original discussion here:

Lightning detector to MQTT2HA daemon.

Guessing author guesses that all of the lightning sensors are made the same way and wired the same way.

So referencing this page for my wiring of my Amazon purchased GY-AS3935 Board


And connecting the above to the RPi using authors wiring schema to RPi.



I almost returned my Amazon purchased GY-AS3935 Board thinking it was defective until I wired it correctly this morning after tinkering with it for 2 days and wondering why it wasn't working.

Testing it now and see the AS3935 Lightning sensor.

Now adding capacitor value of 0xd in config.ini file

# Value to use for your board
# Internal Tuning Capacitors (from 0 to 120pF in steps of 8pf) - A value of [0-15]
# run the script with a --tune paramater to determine value for your board
# NOTE: this runs for 3 minutes so be patient! Then record your best value here.
tuning_capacitor = 0xd

Configuring the daemons to auto start on boot:

1 - NOTE: Daemon mode must be enabled in the configuration file (default).

By default the isp-lightning.service file indicates that the script should be run as user:group daemon:daemon. As this script requires access to i2c and gpio you'll want to add access to them for the daemon user as follows:

# list current groups
groups daemon
$ daemon : daemon

# add i2c, gpio if not present
sudo usermod daemon -a -G i2c,gpio

# list current groups
groups daemon
$ daemon : daemon i2c gpio

sudo ln -s /opt/ISP-lightning-mqtt-daemon/isp-lightning.service /etc/systemd/system/isp-lightning.service

sudo systemctl daemon-reload

# configure services so they start on reboot
sudo systemctl enable pigpiod.service
sudo systemctl enable isp-lightning.service

# start services now
sudo systemctl start pigpiod.service
sudo systemctl start isp-lightning.service


# see if services are running (ensure no start errors)
sudo systemctl start pigpiod.service
sudo systemctl status isp-lightning.service

reboot

Check MQTT status via MQTT explorer


2 - add to Home Assistant Lovelace cards


3 - Add to Homeseer mcsMQTT



4 - Text to speech via SAPI and via Alexa devices
5 - extend sensor using a pvc tube and round plastic ball for mounting RPi/ POe sensor in attic.

AS3935 Lightning Detector Sensor to MQTT - 2023 Version
August 9, 2020, 04:33 AM

Reference:
Tasmota AS3935 Franklin Lightning sensor

AS3935 Franklin Lightning sensor~
This feature is included only in tasmota-sensors and tasmota32 binaries
The AS3935 is a programmable fully integrated Lightning Sensor IC that detects the presence and approach of potentially hazardous lightning activity in the vicinity and provides an estimation on the distance to the head of the storm. The embedded lightning algorithm checks the incoming signal pattern to reject the potential man-made disturbers.

Tasmota driver includes:

support for all AS3935 Parameters
support of all related commands for configuration
support of NF-Auto Function to auto Threshold the Noise Reduction
support of Auto Disturber
support of calibrating the internal OSC with switchable Caps

Wiring~
AS3935 ESP
GND GND
VCC 3.3V
SDA GPIOx
SCL GPIOy
IRQ GPIOz

Tasmota Settings~
In the Configuration -> Configure Module page assign:

GPIOx to I2C SDA
GPIOy to I2C SCL
GPIOz to AS3935

You will need to wire up all of the associated pins for the different boards.

• Always connect CS and MISO to GND.
• If "SI" is present, you need to connect to VCC.

See some wiring on the Board pictures below. I2C wiring



After a reboot the driver will detect AS3935 automatically.



and in MQTT topic when an Event occurs:

{"Time":"2020-01-01T17:07:07","AS3935":{"Event":4,"Distance":12,"Energy":58622,"Stage":1}}
