I had a request today and was not sure if it was possible so I thought I would ask.
Can an email be sent to Node-Red running on a RPi3B+, then make NodeRed reply to the last email’s sender with data?
I want to know the status of a boiler. Temperature, Water Level, Faults, etc.
I want to send an email to firstname.lastname@example.org. Node-Red will receive the email and then poll the boiler for the status values, add them into an email body and send the values back to me.
Been researching for the last couple of hours and there is a node that can send/get emails but no one seems to be using the get email node.
Again, I’m not even sure if it is possible or if an email would even be able to get to node-red.
The company mail server is hosted locally with Node-Red on the same network. I know it can send emails, but not sure if it would be able to receive. Maybe if the email is sent from a device that is also on the network, but not if one tries to email the boiler from home or from a cell phone.
Please share your thoughts.
