fody weather station, wind sensor

[flopp]

@gohan
Thanks for asking :)
It is working good, but I don't trust the wind speed. I have lots of "ghost" indications from the reed
switch, I tried to remove it with code in two different ways but anyway I get some high values. I will order a wind speed meter and check against that one. I also record a slow-mo video when it spins in front of a fan(2.5m/s) and it is correct but it is difficult to test it with 10 m/s,

If anyone are inreseted what's inside the receiver that was included from Fody. It look like this

suddenly it stopped sending data, after power-off-power-on it started to work again

[gohan]

I got an Uno as ethernet gateway with a DHT sensors and sometimes it hangs too after several days

@flopp I'll need to look at the watchdog timers and see if it may help

[flopp]

it stopped working again, this morning. This time it started to work again just after opening Serial monitoring in Arduino IDE

[gohan]

That's normal, upon serial connection the Arduino resets. Try adding the watchdog function. You could also try the newer mysensors library that's in the development branch

That's something new for me. What is this and how do you add it?
Anyone with a link?

[gohan]

Search "Arduino watchdog examples" lots of stuff comes out

thanks :+1:
I did some search and I never heard of this function before.
I will test it in my sketch and see if I get rid of the freezing stuff

I read about watchdog now and as normal way, without extra code, it can check that our code is alive less then 8 seconds.
I want it to send data every 60 seconds so I need to loop watchdog code a couple of times.
I will look at this later

Hi Flopp
I bought the Fody some time ago with the intention to connect it via Blue Tooth to a RPI for awnings control. The idea was that all the calibrating then should be handled by the indoor unit.

Whats your opinion about this?

I'm really new to BLE and Python programming and have so far only been able to make a succesful CONNECT. Is there anybody made something similar? Any help would be appreciated

Hello, I have followed your build and are about to to a similar reverse engineering of a weather station but my winddirection look different and Ineed some input on how I can fix it.

On my there are 8 IR leds on the perimiter and 4 IR sensitiv transistors in the middle. The outer leds are wired 2 and 2 with all the odds having common GND and all the even have common GND. So i have problem on how to turn the led on 1 by 1. Any inputs?
