Samsung Fridge RL38 series – SmartThings API control? (planning to buy RL38C602CB1)

Third party integrations
1

Hi everyone,

I’m considering buying a Samsung RL38C602CB1 fridge (from the RL38 series) and would like to know if it can be controlled via the SmartThings API — specifically: switching modes (Eco / Power Cool) or setting target temperatures, not just monitoring. I don’t own the device yet, so I can’t check its capabilities myself.

From other Samsung fridge discussions, it seems:

– Door contact sensors usually work.

– But temperature values and setpoints often show as “unknown” in Home Assistant (discussion 1).

– GitHub issue #133190 confirms that TemperatureMeasurement and ThermostatCoolingSetpoint often don’t return valid data.

– A current feature request shows missing temperature entities

If anyone owns a RL38 model — ideally the RL38C602CB1 — and has tested this:

  1. Could you please post the full JSON of GET /devices/{deviceId} (capabilities & components)?
  2. Does it include executeMode, thermostatCoolingSetpoint or similar control capabilities?
  3. Any examples of changing modes or target temps via the API would be extremely helpful.

This is for building a PV-based Boost/Eco automation for the fridge before I decide on the purchase.

Thanks a lot!
