WARNING WILL ROBINSON — these devices should never be used in safety critical applications. There are too many ways each of these components can fail and in combinations you will not be able to predict or mitigate. ESPs, SMS devices, and servers can (WILL) fail intermittently and cause your system to glitch and they are not safety certified. Glitches can kill, especially if you are controlling fuel valves or vent fans — even alarms.
I would abandon the project and use the devices for something else - especially if you are a noob.
