Is there any update on the availability of this product?

You can purchase the product now and have it work immediately using our driver.  Saturn South sell direct from Australia to any Control4 dealer worldwide.

How do we buy the Saturn South hardware in the UK? Is the SS9005 the right hardware for three phase or is there a new version being developed? We are building a new house (with a three phase supply) and it would be great to incorporate the right product from the outset. Thanks!

Please contact Saturn South directly for purchase.  The SS9005 is the correct hardware for three phase incoming mains or if you want to monitor 3 seperate circuits.  The SS9007 is for individual circuits / single phase incoming mains.

Also interested in an update and will it work in South Africa?

The product has CE and RCM/C-Tick compliance and will work for 110v to 240v countries.  Please contact Saturn South for any queries about the hardware.

 

We are still working on the T3 application for this. it is an ongoing project which we chip away at between manufacturer sponsored contracts and hope to have it out in coming months.

Thanks I contacted them.

^BTW, where are located?

Not sure how I would shift anything from peak to off peak in a residential setting.  Perhaps pool filters and sprinkler pumps, but otherwise most of the large power users are only used when they are needed.  Its not like I'm going to do laundry a 2am off peak to safe money, or not run AC in the day when needed.    Am I missing something?

Also here are a few of the more popular ones:

A person can sometimes identify problems when there is metering esp when there is some degree of history to compare or other correlating data. I don't think the main purpose of logging usage at a granular level is to shift items to off-peak, but that certainly is a benefit. 20 bucks here or there on a bill isn't going to matter to most people on this forum. 400+ here or there is not uncommon on a large house due to problematic HVAC or other power hungry equipment.

Maybe someone lives in a state where people like to grow things indoors and they like to know the ROI on their output

Actually we found that shifting energy usage from peaks to troughs help quite a bit for dual rate energy billing and also demand response on PV to also assist quite substantially.

I think this could be particularly useful in helping to shave peak demand, especially if you can have more dynamic pricing and more automation in shutting things off when peak pricing is spiking, kind of like how many utilities give you a break on pricing if you install a device that turns off your A/C when demand spikes.

I was responding to the central part of the discussion about how HA can be used in conjunction with energy consumption monitoring to create savings.  I can see that in a commercial setting, but not really sure on ROI for residential unless you live in a mega mansion, etc...

I think you are probably right for most cases except where there is a PV system.

Yeah we went out of our way to pay for CE on the device since the UK is such a big market for us.

Unfortunately only the single phase version is approved for use in the U.K., not the three phase version. It is possible to use three single phase meters on a three phase supply (but it is considerably more expensive and there are minor issues with data reporting). Alan - how would your driver cope with three single phase devices in this setup?

Thanks

Its not realy possible to use 3 meters in conjunction with each other as the readings will be not aligned.  If however you are not fussed with a combined reading and want to read individual phases then it works.  Our upcoming energy interface has the ability to automatically detect all saturn meters in the project, data log then and graph them.

Sorry Alan - do you mean it doesn’t work today (for combined readings on a three phase supply) but it will work with your upcoming energy interface? The response from Saturn was:

“You can use three single phase meters to monitor a three phase site (or three phase load), but there are limitations to the quality of the 'instantaneous three phase power' readings you can extract from such a setup. The long term three phase energy data will be accurate as this is just a summation of the real energy consumed by each phase, but the instantaneous readings may be off from second to second due to slight differences in the reporting interval and lack of time-alignment between the three meters.

 

The difference is only really important if you are interested in faithfully characterising the instantaneous consumption proprieties of your monitored loads. For long duration check metering purposes the aggregations you get by summing the measured energy from each meter should be spot on.”

What i am saying and what Saturn is saying is exactly the same.
