During a power outage, I'm always concerned about overloading the generator. The one I have is 11KW and it will handle most of what I need but there are times when I'd like to know the actual amp draw I'm using.

There are several products on the market that let you do this with a smartphone. These for example, seem like a good way to do it:

Has anyone tried these products, and if so, how well do they work?

I also considered installing a simple ammeter on the generator and monitoring it with a security camera. That way, I could check the load via my home security camera system.

I suppose the best approach is to get a generator big enough to handle every appliance I own, but that isn't an option for me.

Do you monitor your generator output, and if so, how do you do it?

On my 10kw diesel generator, I installed 3 of those cheap volt/amp/HZ meters. One per phase. Might not be exactly what you need though. They also flicker a little bit when recording a video of those, but still perfectly readable.

Emporia Vue 3 Home energy monitor. Just get the "Monitor Only" version for $99. Clamps on the mains and monitors real time energy usage. Smartphone app.

You’ll want two amp meters, one for each hot leg, if you want to know actual amps, assuming you have some 120v loads.
I have a pretty good feel of the voltage and frequency drop vs amp load for my portable 5k generator.
I just occasionally check an outlet with my DVM when I hear it working hard. Most $25 multimeters will read Hz on AC as well as the voltage. I know from actual clamp on current measurements previously made, about what the load must be.
You’re probably looking for something more exact though

I looked at this product on Amazon but was unable to find it's operable temp range. I need to put it in an unheated barn.

The link you provided gave me that info. Thanks!

I built my own panel with amps, Hz, volts for both A phase and B phase, street and gen power. It's nice, because I know when street power comes back on.

You will need a good WIFI connection in the barn.

I added a WiFi extender for other devices I use in the barn. It provides a good strong signal.
