My ZEN-01 ZIGBEE thermostat was working well with Smartthings apps until last week of November 2024 and all sudden temperature settings stopped working , also routines to set temperatures are not working.
other functions like changing mode HEAT/COOL and changing FAN mode Auto/on/off works fine .
Smartthings App receives all the update from Thermostats i.e. any changes made directly on Themostat gets updated in Smartthings app.
Only setting/changing temperature from Smartthings App and Routines to set temps are not working
