I spent quite a bit of time with a Pi and SSL. I want to be able to use Alexa to send commands to it so i need a certificate on port 443 of traviata. I installed Apache and successfully got a certificate. I spent some tinkering getting it working with Nodered. I finally was able to get Nodered to work with the SSL certificate. The settings had to have the exact path to the certificate in Pi. Apache is no longer needed. Unfortunately I did not work on the garage door sensor. Dinner was penne pasta and the leftover spicy marinara sauce.
