Not sure how to take that.
You gave us no indication of you own level of competence.
We're worried about our liability (and yours). I'm afraid "nor would anything come back on anyone besides myself" is not, at least for me, sufficient guarantee.
You gave no technical details in your OP. What you've given in your reply is minimal.
You are (or are a representative of) a business (which was implied but not stated in your OP) and are asking for free help and support from volunteers. Some of us don't routinely do that.
You want a starting point? OK, just this once:

You want a starting point? OK, just this once:
- Find a waterproof temperature sensor that can interface to a Pi. Interface options include I2C, SPI, serial (UART), one wire, bit banged GPIO, USB, ethernet, and WiFi. Additional hardware can expand that to things like RS485 and CAN bus.
- Find a relay that can be triggered by a 3.3v signal and switch sufficient load at 24V.
- Connect to Pi
- Write control software.
