I’m using ESPHome on Shelly 2.5 to control window roller shutters and interlock_wait_time doesn’t work for me. Or maybe I’m just confused.
Take a look at config below. I setup interlock_wait_time: 5000ms and if I understand it right - it should wait 5000ms between switching OPEN and CLOSE relays?
switch:
- platform: gpio
id: open_relay
name: Shelly 2.5 Open Relay
pin: GPIO15
restore_mode: RESTORE_DEFAULT_OFF
interlock: &interlock_group [open_relay, close_relay]
interlock_wait_time: 5000ms
- platform: gpio
id: close_relay
name: Shelly 2.5 Close Relay
pin: GPIO4
restore_mode: RESTORE_DEFAULT_OFF
interlock: *interlock_group
interlock_wait_time: 5000ms
The problem happens when shutter is moving UP, and I click CLOSE button - then CLOSE relay is switched ON immediately (so no 5000ms delay) and OPEN relay is switched OFF right after that.

As you can see from logs, there is no delay between OPEN/CLOSE relays and it results in the malfunction detection. I expect first to close relay that is opened and then open another relay that is closed with interlocking…?
When I add delay manually it works as expected and there is no malfunction detected:
- platform: gpio
pin:
number: GPIO5
id: close_button
name: Shelly 2.5 Close Button
on_press:
then:
- cover.stop: blind
- delay: 1s
- cover.close: blind
But this solution doesn’t seem to be right - and this will cover only physical switch. It won’t cover open/close via HA UI.
