Can we use Rebutton without azure

Dear Team,

I would like to enquire about this seeed Rebutton work on Azure.

Can this button configure work within internal wifi network without external Azure? We want to use it in our factory production area, when there is a machine down. We want the staff to press the button and send the signal to ms sql server as a record. Then when the machine is fixed, they press the button one more time. This is for us to record machine downtime

In theory. But we don’t have a reference for that.
