So basically some beurocrat told me they a new code says I can’t have the current direct wire ge z wave boxes, with a male plug and female receptacle, with my stove plugged into it, to shut my stove off when I leave for safety. Because somehow it’s unsafe. Is there something similar that I can just hide somewhere inside the back of the stove?
Eaton has smart circuit breakers that use WiFi that I feel would meet code. You’d need to verify if they simply use api calls and I would block them from accessing internet and highly limit lan. They look good and I will look further into them (cost).
I limit network to these devices to prevent calls home and downloads of crippling firmware from manufacturers.
EDIT
Not sure if your US but the 240v 40 amp breaker model# BREM2040 shows for $235 at Lowe’s website.
EDIT 2
It looks like it uses post and get commands so their cloud is not needed and local only control is possible. It also looks to use a very well documented api and a developer portal that encourages use by others. If it allows connecting directly to breaker to setup WiFi I would say this is an amazing device
That’s a pretty amazing looking piece of hardware. Not cheap but has lots of capabilities. Thanks for sharing.
Which type of plug would/could that be? Depending on which type usual current limits are indeed somewhere around 10-20A. Not using a plug for a (single phase) load of 40A sounds indeed like a very good idea not only from a beurocrat!
A Z-Wave switch and a contactor. The Z-Wave switch gets wires to close the contactor. You won’t have power monitoring but it is the safest solution. Contactors are made for this sort of thing.
The docs seem to indicate that they require tokens that expire ~yearly. Wouldn’t that still require cloud?
Wait, the documentation says the local communications are over UDP, utilizing keys that expire weekly

I was about to buy a pair of these, but $250 each for a breaker that can be bricked when Eaton decides to EOL them is not a great investment.
GitHub - EatonEM/emcb-udp-master: UDP Master implementation for the EMCB UDP API I guess it’d be possible to file a bug report here, regarding the inability to generate UDP keys without internet and API access.
Good find! My NO-BUY list get’s a new entry: - Eaton
…soon I can actually switch to buy list as recently so many companies like to dive 10 feet deep … that not many serious ones are left accepting the privacy of their customers. For now I actually settled almost exclusively with devices that support esphome after I made some really bad experiences with zigbee gear of various vendors.
