Long story short I'm automating a lot of my stuff at home and as part of that I'd like to be able to replicate the commands sent to my unit (https://www.rinnai.com.au/wp-content/uploads/2017/09/mc_503rc_operating_instructions.pdf) so I can then use them in automations to automatically adjust the temperature based on certain factors.
I did something similar with my ducted aircon, but they have an iphone app and an API so I was able to use Charles as a http proxy to see what the commands were.
Is this possible?
Thanks!
