here you go:
Whoaaa… Be careful. You can buy add-on CTs here.
I think the only difference between Flex and Solar CTs is that the Solar has the sun embossed on it to show orientation. Suspect the Flex looks more like the main CTs.
ps: I did the 400A Dual Panel beta with Solar CTs on the second port so they are interchangeable.
That link takes me to the accessory section of their store, but I don’t see anything but the regular sensors.
got some bad news for you… i think that your ct’s are installed opposite directions of each other if i recall correctly i think they both have to be facing the same way ?
Mine are, in the photo above. Interestingly it seems their software is smart enough to reverse the sense [punintended] of those cables in software. It’s the only way to get the sensors to completely close. Otherwise when you put the cover back on the box it presses the release on the sensor.
Here’s what I see at the top of the store. I’m pretty sure the Flex-Add-ons are the same as the main CTs. @JustinAtSense ?
Ah, yes, thanks. I stared right at it and thought I was looking at the original sensors, but sure enough, they say Flex right there. I was expecting some divergent tech in sensors called Flex.
For 400A and Generator integration, you should utilize the Flex add-on sensors available from https://sense.com/buy or https://store.sense.com/collections/. These are functionally and physically identical to the solar sensors, but come with different packaging and literature to point you to the correct installation guides for these new setups.
Please note that Flex sensors cannot be used in place of the main sensors that come with Sense, which are calibrated specifically for your monitor. They might look the same, but there are differences.
Thanks for clarifying Ryan…
I have a 200A service, no solar and no generator… but I have several noisy circuits that haven’t been picked up well. Could the flex add-on sensors be used to isolate a specific circuit? Example - I have a two-stage heat pump with alt electronic heat that has never been properly picked up. Could I use the flex CTs to monitor/learn just that 60A service downstream from my main 200A service?
The feature is not designed for that. The device would be double counted within the app. But we’re looking at the prospect of developing a feature like you describe, so stay tuned.
thanks. This would be a great value. We have a high efficiency cold climate heat pump system coupled with a variable speed air handler. These two things make our Heating/Cooling energy use nearly impossible for the Sense monitor to parse out. It’s out biggest energy use, yet unknown to Sense. I saw the news of the Flex Add-on sensor cables and hoped this would be the answer. Is there a way that we can be notified if a downstream CT add-on clamp is developed in the future to monitor hard to identify circuits?
Hey @nateherr. We’ll always share an update like that via the community and through our traditional channels.
So the Flex add on sensors can only be used to monitor EXTERNAL sources?
Two years+ in on sense and still I can’t get a read on how much power my heat pump, water heater, sewage pump, and stove are actually using…my 4 biggest devices in terms of draw.
I’ve been looking at switching to something like the Emporia Vue. I don’t know much about it.
I have an all-electric house with propane. My neighborhood might be getting natrual gas, but its pricey, PLUS I have to switch out my equipment. It would have been really useful if I could have actually known how much my usage was of these circuits.
Hi @mike2. Stay tuned for updates in the coming months, there’s more coming here .
Well there is no way to say this without asking for a handout but you should look to the community for testers and free or very discounted. I’ve been really hoping that sense would be a great product and honestly there is no way to put this other than for me its fallen short. I got sense b/c my utility company keeps sending me things saying I’m a top energy user, Sense reports say the same thing, but to date I haven’t really been able to isolate big users nor been able to figure out my “always on” devices in any way, but I’ve stuck with Sense in thinking that its really got a bright future.
What you should really do is also partner with a company that makes electrical panel and come out with a panel-with-sense in a box that as delivered can combine the auto learning of sense with being able to identify every circuit.
Can you imagine the power of saying something like “We can’t figure out your 1000W of always on but we know that 400W of it is on circuit Master Bedroom” or something like that?
Its a long term proposition to be sure. I would have loved it when I redid my panel about 10 years ago.
Agree that there is still lots of room for improvement and that it would be great if Sense integrated with a smart load center (one of their big investors is Schneider Electric / Square D, so I would suspect that there are already thoughts in that direction). On the flip side, there are ways to size up Always On and major energy hogs by using the Power Meter.
For Always On, you can wait until the house is fairly electrically quiet and simply flick each breaker off then back on again, observing the difference in the Power Meter (and presuming you don’t have any optional loads on at the time - lights, motors and heating units off). For the major energy hogs, in my house, I just look at their profile in the Power Meter and estimate how often they come on.
Im not exactly sure but aren’t the sensors supposed to be both with the logo (sticker) in the same direction? to me one sensor is adding and the other is subtracting. Someone please explain this orientation
When you install the sensors and the device does a signal check it will figure out the orientation and provide the correct info, although it may flip back and forth for a few days. I have an extremely tight busbar and the only way to close the sensors completely was to mount one upside down compared to the other. This is why it took DAYS to settle down, if they are both the same orientation, either way, it will recognize it, but even if you put them backwards to each other it will eventually work.
Depending on which batch of flex sensors you received, your stickers may vary a bit from the instructions.
Per the instructions, you want the Sense logo facing the breaker. This means the solar facing away from the breaker.
If your Flex clamps don’t have a Sense house logo, you still want the Sense Solar sticker facing away.
Or to put it another way, if you think of the power coming from your breaker going to your device, you want the Solar sticker on the side where the cable continues out to your device.
@israndy, for Flex sensors, the orientation does have to be correct. It is a different process than the main CT clamps which are able to be installed and not match the instructions.
