Appears to lockup Lovelace after ~1 day of working

[MattW2]

I've been using your integration for about 2 weeks without an issue. In the last couple of days I've been experiencing a lockup of my lovelace UI. At the same time lovelace UI drops out I get the following error in my log file

192.168.1.184 is the IP of my Modern Forms fan which is why I believe the lockup may be related to this integration. A reset of Home Assistant clears the issue for another day. Any suggestions of how to go about debugging this?

I seemed to have solved this issue by making 2 changes as suggested in the comments made in Home Assistant Forums

1) In configuration.yaml I added scan_interval: 30 to the modernforms definiation

modernforms:
  - host: 192.168.XXX.XXX
    name: Bedroom Fan
    light: true
    scan_interval: 30

I changed line 64 of init.py to self.poll = async_track_time_interval(hass, update_action, timedelta(seconds=interval))

2) Added automation as documented by Marko Milivojevic
