Hassio and isy994

I’m using HASS.IO on a Pi3, HA v0.67. I have an ISY 994 with insteon modem talking to various insteon switches.I added the module in configuration.yaml:

isy994:
host: http://192.168.0.3/WEB/udajax.htm
username: admin
password: ****

It automatically detected and added all my switches and scenes and everything. I can control the switches from HA. But when I operate the switches physically, HA doesn’t update with the current state. Or sometimes it will, but I don’t know what’s triggering it. I’ve never seen it change in real time, it is sometimes correct when I first load the webpage.

How do I get HA to reflect the current state of ISY/insteon switches?
