toshiba estia5 (water heat pump) using homeassistant.
How to connect this device (which have not wifi/eth) to HA?

i am new in HA, please be forgiving.
thx.
If the device has a IR based remote control, you can learn the IR code and replay it via ir transmitter
not have IR
Display with buttons for setting is placed on hydrounit.
this hydrounit alows multiple Controls (more displays with buttons) in paralel.
It seems be connected to hydro unit using ModBus protocol (or Jbus or smthing similar rs485)
only 2wires comes inside hydro unit from this unit
this seems be usefull?
Hello folks,
will this works?
i will put rs485 to ttl on Hydrounit Display TB07 A B
between A abd B i have measure 16volts
its not more than rs485 waiting?
i readed range is from -7v to 12v
so they thinking its measured between A B? or to GND each?
and on ttl logic i will do analyse data for power on/off (its enught for me…)
