Is anyone using a current sensing device with Hubitat?
I would like to monitor when a stove/range is being used to start a vent/hood automatically and set alarms when stove/range is left on for say over 1 hour. For safety reasons, shut it off.
I would use rule to turn on a relay on (vent/hood)when the current setpoint is met,
I know some folks have used a device like the following, connected to a Zigbee/Z-Wave contact sensor with externally wired connections, to sense when a device was on or off based on current draw.
I personally have a whole home energy meter system, that allows me to monitor the current/power in most of my electrical panel's circuits with a collection of current transformers (CTs). I use this to know when a laundry cycle starts and stops, to allow notifications to phones and TTS via a Sonos speaker.
Unfortunately, the IoTaWatt device I use is not longer being commercially sold.
There are other home energy monitoring devices that might be able to help. I previously used an Aeotec Z-Wave Energy monitoring device which came with 2 CTs. I had one monitoring my washer, and the other monitoring my dryer.
When you say, "shut it off", you want the hub to shut it off, or you just want to be notified?
I don't know if there that many, what, 50A? switches.
If you just want to get a notification, I think RIB (I forget the company name) has a clamp on relay, that you could hook up to an Ecolink contact sensor, which has terminals for this kind of thing. The Ecolink would tell the hub when the stove is on, and the hub would do its thing. Thing is though, doesn't the oven cycle power to maintain a temp? So, you'd have to figure out something there. Maybe just some other conventional relay that you could tap into some power source on the stove that would be live when it's on. This being done without frying any stove circuit boards, lol.
Let me clarify: We need to control the Vent/hood when the stove/range is being used based on current, Example, when the Current is great than 5 amps, turn on the vent/hood,
In addition, we need an alarm to notify us when the stove/range is left on my mistake.
Im in the process of testing the Hubitat for the HOA of a very large condo complex. We would like to use the Hubitat for monitoring doors, AC units, humidity, ranges, hood, AC floats, etc. One facility alone, we may need over 200 Hubistats
Two things...
First, you should reach out to @bravenel from Hubitat to discuss the commercial use of Hubitat.
Second, please do not use any consumer-grade home automation system for any life-safety systems. They are simply not designed for safety type systems.
You may want to work with an electrician that specializes in industrial kitchens. For something like you're describing, I would not use any home automation system whatsoever. I would use a 'current sensing switch' (like the one I suggested earlier) and have it wired into the exhaust vent hood in a manner to turn it on. Keep it as simple as possible, to ensure the highest reliability.
The goal is not to control the stove/range, monitor only. The only interlock would be relay to turn on the vent/hood based on current. The renters will cook and many do not turn on the vent/hood. Its a known issue in the rental business. All we are doing is turning on a fan.
Everything will be wiring fail safe, normally closed contacts. In the invent the wireless fails for whatever reason, nothing happens, it just dont turn on the fan. The renters still have full control to turn on the fan as needed.
