:new: v4.4 Update – Blueprint fully revised

After months of testing, I’ve published a major retuning of the blueprint. Here’s the updated full description for anyone discovering this thread:

:brain: Smart NIBE – Ultra Adaptive Heat Curve Control (MQTT)

This blueprint provides an advanced supervisory controller for NIBE heat pumps.
It dynamically adjusts the heat curve offset (Modbus register 47011) based on:

  • electricity spot prices
  • weather conditions
  • indoor temperature feedback
  • Degree Minutes protection

:point_right: Without switching the compressor ON/OFF

Think of it as a brain, not a switch.

:arrows_counterclockwise: What changed in v4.4

Spot price influence reduced 3× — indoor comfort now dominates.

Before (v4.3) After (v4.4)
Formula (−0.8 × price) + 4.0 (−0.3 × price) + 1.5
Effect at 10 CZK/kWh −4.0 :x: too aggressive −1.5 :white_check_mark: moderate
Effect at 5 CZK/kWh 0.0 neutral 0.0 neutral
Effect at 2 CZK/kWh +2.4 +0.9

After updating, set these helpers:

Helper Recommended
input_number.indoor_bias 0.0 ← important!
input_number.indoor_response_gain 1.5

:warning: If indoor_bias is set to −1.0 (old default), your effective target temperature is 1°C below your thermostat setpoint. The system will suppress heating even when the room is cold. Change it to 0.0.
