Abuse of Wi-Fi / Wireless for fixed devices; added costs, headaches and dangers. (411)
Wireless (Wi-Fi) is the absolute worst connection method for most fixed devices; for everyone's safety and sanity, avoid using Wireless!
First off Wireless was to provide connectivity for portable devices.
Instead it is abused as a "cheap and easy" way to connect any devices; most if not all know how "cheap and easy" often equates to "bad and hard".
Reasons why Wireless is terrible to connect to fixed devices
1. Failure point. one more device to fail (maybe 2 if extender needed), caused by any number of events
2. Another item to configure (wired is fully automatic by default, works 99.999% of time)
3. Configuration complexity
4. Operation costs, consumes power.
5. Bandwidth, wireless has to share its bandwidth with all devices,. More devices = slower the data rate.
6. Poor or unstable signals. Yes, bad weather can affect wireless just like your TV OTA signals.
7. Vulnerability to external hack. Yes, some people do snoop neighborhoods to hack in home networks, could be your neighbors.
8. Obsolescence. wireless do get updated, for full compatibility all your wireless devices need to be current.
9. Costs. adding wireless device (new nodes, extenders) is not free.
10. Service provider may not allow. Maybe rare, but an internet service provider could bar service (did rear of a case years ago, likely very rare).
11. (anything I miss?)
Examples of terrible use of wireless:
Door bells: Many locations are very difficult to route ethernet, unfortunately limited choices.
Exception:
Thermostats and smoke/fire detectors. Have full control without wireless, very low bandwidth usage
TESLA:
To that end, it is excellent that Powerwall has an ethernet port (with wi-fi). Spending that much for a home battery, it is trivial to run a wired ethernet.
Unfortunately the Tesla Wall Charger does not (Is it only for communication with phone? Is network connection even required for it to work?). I do hope they make a wired version of WC.
Have other pro or con reasons to avoid wireless?

Examples of terrible use of wireless:
- Outdoor security cameras: Noting attenuates a wireless signal more than a radiant barrier and brick, and sheet rock, and studs, and whatever else. Make that $100 camera useless, fast.
- Smart Garage Openers: many of which have cameras. Cameras require strong signal and bandwidth, which is not an area usually well served by a homes wireless.
- Rachio sprinkler control: Sprinkler control systems are often some of the most distant locations on a property. There is a good chance a new wireless node is needed, but often for a little more effort an ethernet wire can be run and have a solid issue. Even worse is Rachio owners complain of inability to connect to wi-fi because of outdated firmware, that can only be updated if it had a wi-fi connection. Cannot do anything without connection. Talk about a face-palm!
