Hi,
thank you for the manual.
According to TP4056 specs LED-Anzeige Rot: (Ladevorgang), LED-Anzeige Blau: (Standby, Ladevorgang abgeschlossen)
In my case I have both LEDs On on TP4056 when solar panel is placed under direct light. Is that intended?
Is it possible, that battery can be charged from solar and can supply power to Pico simultaneously?

Great project idea! Anybody design a 3D printed case for this that they want to share?

Using the TP 4056 for such a Project is not an effective solution, see:

Constructive Design maybe using a MPTT Set Switch, like the Waveshare,

After 4.104 Characters the ‘data.json’ fills the memory of the tiny pico .-/

Question is: How to limit this to get the above project to a functional finish??
An example / code addition (as an update) would be highly appreciated!

TiA – and keep the good work coming.. .
PS: a correspondent Issue in the GitHub Repo was also published.

Som svar på Bigalbo.

In the file bme68x.py the method save_data keeps adding lines to the Jason file. At some point it must be getting too big. You can modify to keep only the last x lines of data_list before saving the file. you’ll have to figure out tue ideal x. You could also keep the current measurement only. This way the file will stay small enough.

I have done this project and had some great results very accurate readings. But have struck a problem it only runs for about 10 2 15 minutes then stops. I have found that if I delete the json file it is the only way to get it back working again Is there a way of stopping it from store them and just send data Have to say tho good job keep them coming plz

Specs of TP4056 says to keep the voltage input in 5.5v or 6V, solar panel of 6V can give 6V and probably 7V+ en some cases. I am about confused about this end. Could you please clarify?

Thanks!
