Printer power switch generating errors

[potchin]

Version of the moonraker integration

1.3.4

Describe your setup

Klipper, Moonraker, Mainsail, Raspi.

Relay connected to the GPIO on the pi to control power to the printer board (SKR mini)

[power printer]
type: gpio
pin: gpio4
off_when_shutdown: True
initial_state: off
restart_klipper_when_powered: true
bound_services:
 klipper
 klipper-mcu

Describe the bug

My power controls though moonraker work fine. When toggling the power switch entity through HA (switch.am8_printer) the UI shows an error Failed to perform the action switch/turn off. state but the power does toggle correctly.

The corresponding error from moonraker.log...

2024-09-04 17:53:12,032 [common.py:build_error()] - JSON-RPC Request Error - Requested Method: printer.objects.query, Code: 503, Message: Klippy Host not connected
2024-09-04 17:53:12,039 [common.py:build_error()] - JSON-RPC Request Error - Requested Method: printer.info, Code: 503, Message: Klippy Host not connected

Klippy being disconnected is expected if the printer is off. Any suggestions?

Also noticed that the state gets out of sync. Eg, the state of the switch entity in HA is "on" but its actually powered off (which is correctly shown in mainsail)

Could you get a full copy of your log and reproduce the problems

Also having this issue with a Wemo switch.

I have this same issue with the latest updates on my relay connected to the GPIO on the pi to control power to the printer board and an LED light strip.
