Assuming the OP has a gas dryer you just plug it in to this and this into the wall, if you have an electric you need something capable of 240v service. All washers I've seen for home are 110v as well so those plug right in. You should still check the wattage/amperage draw against the switches capability but the ones of this style usually have a pretty high limit.

How well would this work if i put it between the wall and and power strip that connects all of my PC stuff? I always wonder how much energy i'm burning there.

They don't list a wattage limit, just 15A 120V (which translates to 1800W in an ideal world), but they reference refrigerators, AC units, and Microwaves, so unless you're running something SERIOUSLY power hungry (multiple computers, a bitcoin miner, etc), I'd think you probably will be okay.

Just for comparison - Many refrigerators use 1000-1500 watts at startup/surge, Microwaves are regularly 1100-1300W, and I've seen portable air conditioners as high as 1800W.

It's not going to identify what is using the load, however, so you'll get a gross usage reading with no real info as to what's used individually by your PC, monitors, external drives, modem/router, etc.

That is basically what it is made for. It's not going to break down each and every thing you have connected, but it will show you the overall total

Think of at as a Kill A Watt type device, but depending on what Z Wave hub you are using, it will also log the usage and let you trigger different types of events.

Yes - sorry, gas dryer. But they still need electricity for the control. If you were using this for an 'end of cycle' type event, you would just use the wattage or amps. When it drops to zero, the load is done

This may be a dumb question, but does this z-wave device act as a repeater as well?

Looks like it should - one of the photos states that it is a z-wave plus repeater.

What is the difference with z-wave vs z-wave plus? Would a z-wave plus device be compatible with a z-wave hub?

Quote from GrnMnky : This may be a dumb question, but does this z-wave device act as a repeater as well?

Yes, any Z-Wave device which is not battery-powered will act as a signal repeater by default. Once you add it to your hub, we recommend network repair / rediscovery so the hub can change any communication routes to optimize the network if needed.

Quote from finalresort : What is the difference with z-wave vs z-wave plus? Would a z-wave plus device be compatible with a z-wave hub?

Z-Wave Plus has much better range and uses less power which means longer battery life for battery-powered devices. This is because the devices need less time to communicate, making the network faster and more reliable.
Z-Wave Plus devices will work well with a Z-Wave hub but some of the benefits like additional security or network wide inclusion may not be supported by Z-Wave hubs. Compatibility depends on the software part primarily though so as long as the hub is frequently updated and it's open to integration with other brands, you should have no problems using Z-Wave Plus products with Z-Wave hubs.

This particular plug works great for on/off control and status updates with any Z-Wave system we've come across but power monitoring and advanced settings will only be available on open platforms like SmartThings, Hubitat, Vera, Fibaro, or HomeSeer (not alarm panels equipped with Z-Wave or some more limited solutions such as Wink).

Quote from finalresort : What is the difference with z-wave vs z-wave plus? Would a z-wave plus device be compatible with a z-wave hub?

Z wave plus devices mainly offer lower power use, OTA firmware upgrades are part of the standard and there are additional frequencies. You can use both plus and standard z wave devices with any home controller that supports zwave. You may get better performance with a zwave plus enabled hub. I have a ton of each kind on my smartthings v2 hub and they all work fine.
