Hola,

Also see https://www.youtube.com/watch?v=6P6reXvc5UE for a quick example on how you can convert the timestamps yourself.

Nothing fancy there, really, these were some 3.3V (5V is good too) active buzzers . They are controlled with a NPN transistor so you can use pretty much anything. You can also connect a LED instead. Here is another link: https://www.aliexpress.com/item/33059794164.html and a picture attached.

Welcome Rob and thank you.

There are a few implementations using the code for upload. You need to do the HTTP call, having all those parameters added to the url. Can you post your work so far?

Uhm… that’s a bit complicated as that file is encrypted. Data that is not being sent to the server will be stored there, to allow sync later on.

I would stick to the standard CSV files. If WIFI is connected, the CSV files will be generated.

Great! Mail sent.

Sorry for the confusion,

You can also look at the KIT1, that is even lower cost and you can hack it to add more sensors on it.

hi Catalin, some people seem to have trouble running the firmware update. Should you have the time, please consider writing a short tutorial on the blog to explain the steps you did . I can also send you the latest firmware.
