Thank you Daniel for your answer!
I exlplain you what I’m trying to do now. I discovered that every gym has its own web page. So, I could do a list of the web pages of all the gyms in my town in google sheets and use the formulas in the image below:
My bot could be structured as follows:
2) get a row -> go to google sheets, row 2
3) update a row -> update A2, inserting “ON”
4) automatically the formulas in column D start their job
4) list row + message -> text all the datas in column D
5) update a row -> update A2, inserting “OFF”.
I think this could bypass my problem, but now I have an issue with google sheets: when I use one of the formulas to import datas, I only obtain partial datas.
Anyway, thank you for your answer!
