Watching Single Appliances in WoowTech
Beyond the whole-house totals, WoowTech lets you zoom in on one device at a time so you can see exactly which appliances are eating into your bill. The same approach works for water as well as electricity, giving you a per-device breakdown of both.
Hardware for Measuring Power
Smart Plugs
A smart plug slots in between the wall socket and whatever's plugged into it, metering the energy that passes through. Pick the radio that matches your setup — they come in Zigbee, Z-Wave, and Wi-Fi flavors.
Smart Relays
A relay tucks in behind an existing wall switch and makes it controllable from WoowTech. The advantage is that the original physical switch keeps working, so anyone can still flip the light by hand even while WoowTech manages it in the background.
Hardware for Measuring Water
To meter a single fixture or appliance's water use, you can reach for:
- A smart water meter that supports per-device readings
- An inline flow meter plumbed onto one appliance
- A connected appliance — a washing machine or dishwasher, say — that reports its own consumption
The water usage guide lists more hardware and integration choices.
Devices That Only Report Watts
Some equipment — think air conditioners or boilers — surfaces a live power figure in watts but never an accumulated energy total. To put those on the Energy Dashboard you first convert power into energy with the Integration (Riemann sum integral) integration, which adds up the power readings over time. The energy FAQ walks through the configuration.
Parent Devices and Avoiding Double-Counting
You can chain devices into a hierarchy by naming an upstream (parent) device for each one — and this works for both energy and water. The point is to stop the numbers being tallied twice when, for instance, you measure a whole circuit and also measure individual gadgets hanging off that circuit.
How to set it up:
- Add every device you want to track as its own individual device first.
- Go back through them and assign one of the already-added devices as the upstream device for the others.
One constraint to remember: only devices already present in the individual-devices list are eligible to be picked as an upstream device for another.
