Tolerance for quick turn on/off not respected?

[MaJerle]

Description

I have my tolerance set to 0.3 degrees which should not trigger the thermostat to go on until temperature drops to below target - 0.3. But I am noticing that it goes on immediately as soon as temp goes below target.

This is annoying since it can change the state every 10 minutes or so, draining the battery.

Steps to Reproduce

1. Create BT
2. Set tolerance
3. Try

Expected behavior:

When tolerance is set (in my case 0.3) I'd expect the values are respected.

Actual behavior:

The thermostat goes on as soon as temperature goes below the target, not respecting the tolerance values.
In my case, heating is turned on as soon as temperature goes to 21.9 while set to 22.
