Replace a control module in central heat unit in a basement that failed because it got flooded. 

Matlab modules might have canned algororhitms, but not sure if this is what you need.

Typical parts to fail on electric stoves: control boards, thermostats, spark switches, spark module, bake element, broil element.

I basically purchased the program to work through the online training modules as I could find time to do so, a couple hours here and there.

While you're already headed there, it's a good time to do preventive maintenance (smoke detector batteries / tests, furnace filters, checking for leaks under sinks, etc), as well as a general check of the condition. 

Unable to install hardwired so looking at 10 year battery models.I’ve browsed Amazon and Home Depot and - while there are many options, the pricing is just mind boggling.

I get about a year out of the batteries in the Schlage.

I know people that use that time to not only check the condition of the property, but also to change the furnace filter, replace CO2, Smoke alarm batteries.

It also has a CO detection shutoff which is important but changing/recharging the batteries for the remote ignition was tiresome. 

Ring tends to do this a lot; anytime leaves blow in a different direction it sends a notification lol but there is a way to adjust the settings for Ring so that it isn't destroying your phone's battery or filling up your notification center with too many notifications).
