Your Question

Hello,
I have a Samsung system in my house with the following components:

Outdoor heat pump unit:
1 AE120MXTPGH/EU

Indoor hydronic unit:
1 AE160BNYDGH/EU

Ducted AC:
3 AE022ANLDEH/EU
1 AE036BNMPEH/EU

Domestic how water tank: Cordivari, controlled by the hydronic unit.
Underfloor water heating: controlled by the hydronic unit.

I was thinking about connecting the M5STACK ATOM Lite + M5STACK RS-485 to the F1/F2 of the hydronic unit (internal) with a small 10cm stub. In the F1/F2 of the hydronic unit there's already a bus cable to all the ducted ACs.

HVAC System Type

NASA (Bus Protocol)

ESP Device Model

M5STACK ATOM Lite + M5STACK RS-485

Connection Pins

F1/F2

What would I like to achieve

1. monitor the DHW tank temperature
2. set the DHW working mode (eco/standard/etc)
3. change the DHW tank setpoint
4. turn on/off all ACs
5. change all ACs setpoint temperature
6. change all ACs mode (cool/heat/etc)
7. monitor the heat pump efficiency (cop, frequency, fan, defrost, etc)

Yes, but I had a better result with https://github.com/Beormund/esphome-samsung-nasa

I only have an outdoor and indoor unit for an air-water heat pump. Following my yaml.
I guess you'll understand names even without translations

Thanks a lot, that's very helpful. If I got it correctly though, the integration you mentioned doesn't (officially?) support ACs, so I wouldn't be able to control them.
Well, let's see once the M5 arrives :)
