Hi guys, I was wondering if anyone would have any idea to monitor an oven if its ON for a long period of time to avoid an accident... And based on conditions to trigger notifications. 

I thought about a thermostat on top of it, but doesn't look good.

I thought also on Insteon Power Synching Controller, but that doesn't fit that huge plug... 

So guys, any other solution ?

 

Thank you!

You could use a MAMAC Systems CT800 {solid core}  or CT805 {split core and can be snapped over a wire without disconnecting it}  current sensor. To trigger an I/OLinc. If you have access to the oven's wiring. So you can slip the sensor over the one of the AC input wires to sense when it is On.

The CT800 senses .5 Amp to 200 Amp currents and has a dry contact output. That can trigger the sensor input of the I/OLInc.

If the oven has some electronic controls. You may have to pick the AC line not powering the controls as .5 amps to the controls may trigger it.

Thanks again Brian for your answer... That goes a little beyond my knowledges... which wire should I use to sense?

NK Technologies also carries a line of current sensing switches that easily connect to IOLinc sense and both NO and NC available

I would depend on the the oven.

The sensor would have to slip over one of the incoming power connections. Maybe where the line cord is internally connected to the oven.

If it is a 220 volt model. One of the incoming lines.

This guide was for a Dryer but should give you added information on how it can be done.

Yep, this solution needs more knowledge than I have... Thanks guys for all the input

If it were me I would use a cai webcontrol board with a 1-wire temp probe and glue the temp sensor to the back of the oven.  The cai can be quickly programmed to post the temp to an ISY variable and you could write a program on ISY to notify you at some particular temp or if it stays above some temp for some period of time.  Of course this is not the temp inside the oven, but I am quite certain that if the oven is on, the surface of the back of the oven would be quite warm.
