Ok I'm not a programmer, but trying to learn. I am using my Pi 3 to control a door on my chicken coop. I run a crontab twice a day to open and close door. I had it set up to run a python script to open or close the door and send a text message door open, or door closed. I was using Twilio, but now you have to your phone registered and a lot of crap (which all cost more money). I have used it for years very cheap, but now everyone wants paid for the service. Is there a way to code it so I don't need any of these third-party system. I looked into ClickSend it also is going to cost to much for what I am doing. I have read a lot on this but seems like all the info I find is outdated. If someone could help me out I would appreciate it, Caution I will probably need to be spoon fed. As I said I am not a programmer just trying to learn it's all very interesting to me.
