Type conversation problem - RPC setValue - MQTT - MAX!

Hi,

It seems something went wrong by using setValue method over MQTT.

I am using that to set temperature of MAX! basic thermostat.

When it is OK the given value should be detected as ‘Integer’ or ‘Float’ depend on the passed value is eg. 21 or 21.5
like this way:

11/10/23 15:46:55.930 MQTT Client: Info: MQTT RPC call received. Method: setValue
11/10/23 15:46:55.931 RPC Server (Port 2001): Info: RPC Method called: setValue Parameters:

(Integer) 1
(String) SET_TEMPERATURE
(Integer) 21

10/04/23 20:18:00.770 Module MAX: Info: SET_TEMPERATURE on channel 1 of peer 3 with serial number PEQ1012669 was set to 0x2B.


The problem visible as the value is detected as String instead of Float and the temperature is set to 5 all the time instead of xx.5 as expected.

11/10/23 15:45:31.217 MQTT Client: Info: MQTT RPC call received. Method: setValue

RPC PHP script is still fine:

11/10/23 13:57:08.620 Script Engine Server: Info: Starting script "/var/lib/homegear/scripts/inline.php" with id 1.
11/10/23 13:57:08.627 Script Engine Server: Info: Client number 0 is calling RPC method: setValue
(Integer) 4
(Integer) 1
(String) SET_TEMPERATURE
(Float) 21.5
11/10/23 13:57:08.627 Module MAX: Debug: SET_TEMPERATURE of peer 4 with serial number OEQ0943767:1 was set to 2B.

The homegear version last known was good is “0.8.220105-3478”. Unfortunately that docker image version is lost due to SSD failure, I could not double check easily.
All recent Stable(0.7.51-3497)/Testing(0.8.1-3519)/Nightly(0.9.23101322-3671) docker image having that issue.

The Mosquitto (2.0.10) and OpenHab(3.2.0) version are the same as before only Homegear version is changed recently.

Do you have any idea what could be wrong?
If you need more detailed Debug I can provide for you.
Thanks in advance
