KNX Cover Control with Inverted Position Feedback (Home Assistant Blueprint)

This Home Assistant blueprint allows you to control a cover entity via KNX group addresses
(Up/Down and Stop) and sends an inverted position feedback in percent back to KNX.

It is designed for installations where KNX uses:

• 0 % = fully open
• 100 % = fully closed

while Home Assistant uses:

• 0 % = fully closed
• 100 % = fully open

So the feedback is automatically inverted:

• HA 0 % → KNX 100 %
• HA 50 % → KNX 50 %
• HA 100 % → KNX 0 %

The feedback is sent whenever the cover position changes, no matter if the movement was triggered from KNX or directly from Home Assistant.

Features

• Control a Home Assistant cover via:
  • KNX Up/Down group address (1 bit, DPT 1.xxx)
  • KNX Stop group address (1 bit, DPT 1.xxx)
• Send inverted position feedback to KNX:
  • KNX position feedback group address (DPT 5.001, Percent 0…100)
• Optional inversion of Up/Down direction
• Optional feedback cooldown to reduce KNX bus traffic
• Fully configurable via UI (no YAML editing needed after import)

KNX Group Address Mapping (ETS)

Function	KNX Object Type	DPT
Up / Down	1 Bit	DPT 1.xxx
Stop / Step	1 Bit	DPT 1.xxx
Position Feedback %	1 Byte	DPT 5.001

Example Logic

Home Assistant	KNX Feedback
0 % (closed)	100 %
25 %	75 %
50 %	50 %
75 %	25 %
100 % (open)	0 %

Requirements

• Home Assistant ≥ 2026.1
• KNX integration configured and working
• Cover entity with current_position attribute

---

Use Case

Perfect for KNX wall switches and touch panels that show the blind position in percent and expect:

0 % = open, 100 % = closed

while Home Assistant internally works the opposite way.
