Well, I had put up my Weather Station on my roof top last Sunday, and this Friday - big thunderstorm.
All of a sudden, lightning strikes. Is was powerfull enough for us to feel the blast of the impact with the air (Windows were all open) and the bang was incredibly loud. After I had calmed down the kids, I went on to check on the electronic equipment. All that was not hooked up onto a lightning protected device had been unplugged. So we had no damage on this side. However, everything that was not protected by walls got fried electronics. The entire street went dark. Checking the weather station, I realized that all of a sudden the raspberry PI Zero WH was loading 500mA of power instead of the 120mA it did in normal operations. The temperatur of the device itself went up to 80⁰C against the usual 30⁰C showing something was broken.
After analysis on what had happened, the lightning struck a neighbor 20m away. The EMP dsischarge seems to have fried all electronics not unplugged in his houses, and all electronics that were not protected by walls in the near surrounding.
So - it too me 6months to get everything up and running the way I wanted it - and 5 days in Service lightning strucks it.
That is what I call: Bad luck?
I'll get it down as soon as I can get hold of the equipment again, and see what broke down. The PI seems to be dead. Don't know about the rest yet.

Holy Cow! Well, there is nothing that could have saved that. It probably wasn't an EMP discharge if the unplugged equipment wasn't destroyed. The lighting came in through the wires.

I'll be able to tell more when I've taken it off the roof. :}
The unplugged equipment was in house behind armored concrete walls. Well - we build houses with stones over here. So there was some protection... Reason WiFi is pain to setup here

Take some pictures. This is a first for a unit being destroyed by lightning. We had some close hits on Project Curacao3 but it survived. skyweather.weatherstem.com/curacaoBP

So - I finally (after vacation etc.) managed to organize equipment to take down the Weatherstation from my roof. After doing some troubleshooting, the only defective device is the raspberry PI zero W. After powering it up, it starts heating up and in the process uses more and more current (up to 700mA and ~80⁰C) until it kind of crashes. After replacing the raspberry PI - the weather-station works again. I'll put it back out, but I'll have to add some cables (Power supply) and eventually ethernet. Or I'll add another AP and configure it as Roaming device for the current setup. Anyway - all sensors are up and running (as it seems).

PS: I have the impression the AQI Sensor is dead. I can connect to it - but getting no data. Usually I always had some dust-particles. Can't imagine that at this time there are none.
pi@weatherpi:~/SDL_Pi_SkyWeather $ sudo python testDust.py Air Quality Measurements for PM2.5: 0 particles/0.01ft^3 0 ugm^3 Current AQI (not 24 hour avg): 0
Air Quality Measurements for PM2.5: 0 particles/0.01ft^3 0 ugm^3 Current AQI (not 24 hour avg): 0
You have any electrical layout to check what may be dead? I suspect the LED or so. If that is the case I should be able to replace it. If not - I'll need a spare somehow.

Smurphy,
We have them on the store. That is not looking good.
The sensor is a black box to us unfortunately.

I have found the sensor in a European neighbouring country. Will be faster, and the transport CO2 footprint will be way lower. Will report back when installed.

Good deal. Looking forward to the report.

And the Thunderboard is also dead. I kind of expected it. From memory, there is a small copper coil on it. If the EMP that actually destroyed my Raspberry PI hits that coil, I bet there was a decent discharge hitting the electronics behind it. No wonder.
Now - I didn't find any replacement part over here for that one. However, shipping costs would be way over the price of the device itself. @sdl: Do you know a partner shop in Europe that would have such device? Or are there any advice in connecting (I have no issues soldering stuff together) one of the regular boards one can find for the arduino/pi devices using the AS3935 ThunderBoard? (http://www.embeddedadventures.com/as3935_lightning_sensor_module_mod-1016.html in the Uk for example)
Thx for any advice.

Thanks. The Wiring should not be an issue I'll check it out.

So - they seem to be out of business. Only automated mail, no phone reachable. Guess I lost my money on them. Will check for another alternative.
Thx

They should work! Needs to be on the I2C bus and you may have to change the i2C address that our driver is talking to. Remember that the AS3935 is flaky on the I2C bus.

So, I connected my external module. How do I configure the address?
$ sudo i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- 48 -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- 5c -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- 73 -- -- -- 77
Also, I see the 5c showing up only on every second detect poll. How do I change the address for the bus?
The testing code has various places to set it.
Thx for any hint.
