Cycle duration not working

Cycle duration is set to 30 minutes but stops after 5 minutes

Hello @rbjoensen,

Can you give me more clues. What is stopping after 5 minutes ? I see your configuration seems correct:

cycle_min: 30

but ytour thermostat is just not heating (no need):

current_temperature: 19.9
temperature: 20
hvac_action: idle
...
on_percent: 0.16
on_time_sec: 0
off_time_sec: 1800

Your thermostat is not heating because you tell him not to heat under 5 min (which is a good thing):

minimal_activation_delay_sec: 300

For me all is normal.

[rbjoensen]

sometimes it is more than 5 minutes but never more than 10 minutes

[jmcollin78]

What do you think is a problem ? All I see is normal. The cycle is really 30 min, If I look at your graph.

[rbjoensen]

No about 9 minutes

[rbjoensen]

but the gap between heat is about 30 minutes

[jmcollin78]

Eaxh cycle is 30 min long:

You are confusing cycle length and heat period. During one cycle (30 min) and depending of the conditions, VTHerm can heat from 5 min (the threshold you gave) and 30 min. Curently the heating duration length is 9 min (28 % = on_percent value).
