Power measurement switch

[Reinhold 18]

I have a Bosch CMG633BS1 combi oven and i wil use a fibaro switch for power measurement. But the oven use 3600w but a wallswitch can max 2500w. Is there a solution to measure the power?

9000W

 

for example

Aeon Lab Smart Switch  ZW075 up to 16A.

TKB home Switch 16A

[Reinhold 18]

This give me the same results like the fibaro switches?

[cag014 731]

Fibaro switch is up to 10A only

TKB home up to 3500W ...

But get i the results in the consumption panel? the same graphs as the Fibaro modules?

Yes, exactly the same graphs.

Consumption panel uses received power values and makes the chart, doesn't matter where the values came from...

Thanks for you answer. it is a pity that fibaro does not have a module that can do this.

Before you buy anything, can I recommend a topic in which I explained a lot about relays(*)?

 

 

I think your magnetron-combi oven does not qualify as a "resistive load" so most of the relays are not really suited, please check the specs before you buy... Even when you use the relay only for power measurement (never turning on/off the load) you might get issues. For instance, the inrush current of the oven might trigger an overload. I do not own a device that can do 16 A but I do know the Fibaro Wall Plug (second generation) detects overload and turns itself off...

 

(*) EDIT: I meant to say... I topic with lots of very useful contributions from other users too... But I elaborated on quite a few things. So I am biassed towards this topic... you might want to check other sources too.

my proposal, use Qubino Smart Meter together with IKA232-20/230 V (if you use only two wires for the oven). When you need to power it with 4 wires (L1, L2, L3, N), then you will have to wait till Jan 2018, as Qubino will release then Smart Meter for 4 wires (and to switch on/off you can use then BICOM432-40-WM1). As the Smart Meter speakes z-wave, you can control it then via scenes or association.

Thank you for pointing out that some ovens use 3 phase, this complicates matters. Though not the model mentioned by @Reinhold, it comes with a standard 16 A EU plug.

 

I see you and I are on the same wavelength (stupid  Z-Wave pun intended), your advice is a solid, robust 32 A contactor from a known brand (ISKRA)...
