IoTaWatt install inside panel?

Looking to get started with IoTaWatt. Is it possible to install IoTaWatt inside the panel?

I know other energy meters have hardwire power connections, but does not look like IoTaWatt has a solution for this. I realize that the wifi will be severely impacted, but I have an access point within a few feet of the power panel and think it will be OK. Live in a high-rise condo (in California) and panel is behind a bedroom door. I don’t really have an option for a subpanel without tearing up walls. There is plenty of space in the panel.

Suggestions?

There has been at least one report of a user doing that, but the device was not intended for mounting inside a panel and the issues, if any, have never been explored with the ETL safety test engineers.
