I want to use the Maker API to control the setpoint of a thermostat.
The thermostat supports setpoint in increments of 0.5 and I can set decimal values in the web interface :
and i can set integer values with the API using http://xxx.xxx.xxx.xxx/apps/api/1/devices/33/setHeatingSetpoint/15?access_token=,
but when i try to set a decimal value with http://xxx.xxx.xxx.xxx/apps/api/1/devices/33/setHeatingSetpoint/15.5?access_token=, i get this error : {"error":true,"type":"java.lang.Exception","message":"An unexpected error occurred."}
