Samsung AC / External temperature

kumy · November 17, 2019, 9:45pm

Platform information:
- Hardware: x86-64, HP microserver gen8
- OS: Ubuntu 16.04.6
- Java Runtime Environment: openjdk version “1.8.0_222”
- openHAB version: docker image openhab/openhab:latest (2.4.0)

I’m trying to display external temperature along with the internal using samsung AC binding. It seems that the value is read without error and stored into ac_outdoor_temp, but it doesn’t appear in the frame. (See lines:

2019-11-17 22:35:45.969 [DEBUG] [.samsungac.internal.SamsungAcBinding] - Trying to find item for: Salon and cmd: AC_OUTDOOR_TEMP
2019-11-17 22:35:45.969 [DEBUG] [.samsungac.internal.SamsungAcBinding] - ac_outdoor_temp gets updated to: 54

Any idea on how to display AC_OUTDOOR_TEMP value?

$ cat rules/samsunac-ext-temp.rules

And if I enable the or Item kodi_kodi_337f8b28_currenttime changed I get:

According to the docs this command is not supported

Hi @vzorglub,
thanks for your response. I suspect the doc does not reflect the actual code of the binding. Maybe @steintore is around to confirm?

Looking at file https://github.com/openhab/openhab1-addons/blob/master/bundles/binding/org.openhab.binding.samsungac/src/main/java/org/openhab/binding/samsungac/internal/SamsungAcBinding.java the log I get for it let me think it is parsed by the binding

As there is a default in the switch case conditions, and the log from line 375 is the one I get for this value.
