HASS + Konnected.io + Relay Switch - Keeps switching off

Hi all,

I’m fairly new to HA and in the process of migrating from SmartThings across to HA, loving it so far.

The Context:
I have a dashboard tablet which gets power from a relay-switched power source.
I used to switch this relay via WebCore on a schedule to exercise the battery.
This relay is connected via the Konnected.io board and successfully activates from HA when calling a script or service.

The Issue:
The Switch successfully flicks on, and charges the tablet. However it reverts to off again after a varied amount of time 10seconds out to 30 seconds.

config.yaml

konnected: !include konnected.yaml

Konnected.yaml

api_host: https://<localip>:8123 ### IP address of Home Assistant
access_token: !secret konnected_token
devices:
  - id: <mac removed> ### Alarm Panel
    host: x.y.z.73
    port: 18300
    binary_sensors:
      - zone: 1
        type: motion
        name: 'Hallway'
      - zone: 2
        type: motion
        name: 'Lounge'
      - zone: 3
        type: motion
        name: 'Dining'
    switches:
      - zone: 4
        name: 'Tablet Power'
        activation: high
      - zone: 5
        name: 'Buzzer'
        momentary: 35
        pause: 55
        repeat: 4
      - zone: out
        name: 'Sirens'
 

I’ve tried scripts, scenes and Service calls via the dev menu.
Each time, the relay successfully switches, then it turns off again (meaning the tablet never charges)

I can’t spot anything specific in the logs.
I’m not using MQTT, just the native integration (which I’m assuming the above yaml overwrites the config of) which i believe is an HTTP API post call?

Are there any logs I can enable that might hone in on post calls and responses?

I’ve seen in previous posts people saying MQTT didn’t receive a state reply… but this isn’t MQTT so I’m a tad lost.

Thanks in advance

No one have or had a similar issue?
