I have no comparison to conventional electric - it might still be cheaper with induction. But I use induction for 10 years now, exclusively (and had gas before that).

But it’s the general cooking as well. Two ovens (One with steam,one conventional,of course not always used together,but it happens), other kitchen stuff, it is fairly interesting how big the peaks are that are created this way. And don’t get me wrong - our kitchen is kind of a upper market one in terms of appliances (the wood on the other side is run off the mill and was dirt cheap),but it’s also the thing that brings my family daily joy and I am more than happy to pay the power bill - but nevertheless I am still surprised.

I try not to go below 47%

Induction

Bird-net pi also runs here,but it provides audio identification,not optical identification.

I can see if someone is on the toilet and having a Nr.2 by checking the power draw of the Japanese style toilet. (I also have a presence detector). I do not monitor the first part intentionally, though.

I unintentionally catched some birds eating on camera and that led to us installing a designated bird cam - in a 3D printed bird house. The AI model for identification is still in the works though - there aren’t any good European based ones available as open source so I still will need to work out my own.

I found out the kid is reading FAR more than thought and is using the PC far less than I thought. Sorry kiddo!

CO2 is going up far more than expected,yes. What I found more interesting, though, is the direct connection between the humidity and my sinus infections - I always get them if my room air gets to dry.

Cooking releases an ungodly amount of VOC and uses FAR more electric energy than I thought.

And: After two years of optimisation I can control the temperature in two very sun exposed rooms just by using the covers and a weather forecast extremely well. Means they are up to 4° colder in the summer than before and 10° warmer in winter. Sadly this does not apply to all rooms.

And last but not least: Heating is the only point where home automation really saves energy here.
