Automate an Electric Blanket - Power On/Off

If there is one thing I would really like to somehow automate - just a simple on or off, it’s my electric blanket control! I know this would be EASY if it were the type of control that had a physical on/off button since I could just plug it into a controlled power outlet, but unfortunately I have a control like this one pictured below:


When the power is on and power is removed, when power is restored it returns to it’s powered off state. Was thinking I could use some sort of dry contact switch (a Sonoff for instance) to turn this bad boy on or off … but of course I would have to open up the unit and figure out where the contacts are. Wondering if anyone has attempted something like this? Any ideas? Does this seem doable?

Thanks for any help or ideas you can offer!
