Thanks a lot Pete! I have a lot of reading to do. I’m currently trying to go about this problem using IFTTT location and a webhook to trigger a relay controlled with blynk. Theres a few other threads that talk about this topic more in detail so ill post my related questions there. Thanks again! (but feel free to leave a comment here if I’m totally on the wrong track 
)
