[mgiesl2s]

Hi
I want to use the action mypyllant.set_dhw_circulation_time_program

But it doesn't work. Is it a bug?

I use the example code:

action: mypyllant.set_dhw_circulation_time_program
target:
entity_id: water_heater.my_home_domestic_hot_water_0
data:
time_program: |
monday: - start_time: 330
end_time: 1260
tuesday: - start_time: 330
end_time: 1260
wednesday: - start_time: 330
end_time: 1260
thursday: - start_time: 330
end_time: 1260
friday: - start_time: 330
end_time: 1260
saturday: - start_time: 450
end_time: 1260
sunday: - start_time: 450
end_time: 1260
