TPMS + propane tank monitor + water tank monitor

Hi Everyone

I own a motorhome and would like to add the following sensors (and alert on them when i am not there)

  • TPMS, i have searched the forums and can’t see anyone who has done this.
  • A propane tank monitor to tell me the % left in the tank
  • A water monitor to tell me when i need to refill the fresh water tank.

For the propane, i am thinking of the Mopeka (If they will release their protocol interface protocol.

Thanks in advance
