Hi all, I am curious if anyone has tried the newer line of GE/Jasco ZWave Plus switches/Outlets?
I am specifically curious about their powers consumption. The electronics involved in the Z-Wave circuitry and relay.
I have over 30 of the original line of ZWave products and have a device (Kill-A-Watt Meter) I can use to plug in between the outlet and cord of a device to measure power consumption. I attached a power cord to my switches and outlets and found that they pretty much all steadily consume 1.5 watts of power when on or 1 watt when off.
The new Z Wave Plus line claims (on the jasco site) to use 50% less power but gives no specifics. Can anyone confirm the amount of power they draw in watts or KW/h ? I am also curious about the switches with built in motion sensors? How much power do they pull?
**EDITTED, My kill-a-watt meter was pulling 3 watts on its own so I originally wrote this out as 3 watts per device not the 1 and 1.5 depending on if the relay was energized or not. I ended up calculating based oon amperage draw and voltage present.
I started it to save power when my kids leave lights/fans on all over the house when they leave the room/house. In that regard its been a success. That combined with all LED bulbs has had an impact on my utility bill but I knew these were going to be about a $10 a month cost to run so many as it is
Still though, wouldn’t mind shaving that in $10 to a $5 a month cost if the GE site is to be believed.
Right, it’s all about comparing the new Z wave devices to the devices that they replaced as far as energy savings.
With regard to the specifications, a Z wave plus chip replacing a Z wave classic chip in the same device should show right around a 45% energy draw savings. However, you will find that many manufacturers added more features to the new zwave plus models, so there’s no telling whether the new models will be more energy efficient than the old without just checking individual specs or measuring.
