Smart meters use Zigbee to link to both IHD (In Home Display) and CAD (Consumer Access Device) devices.

Typically a customer get an IHD along with their Smart Meter installation. This then visually shows energy use on an LCD screen.

I am more interested in the possibilities of having also a CAD device so I can link it to a smart home platform. There are some devices to do this but it seems most might be still limited to use with SMETS1 devices. For example the Rainforrest EAGLE-200 https://rainforestautomation.com/rfa-z114-eagle-200-2/ and TheRetriever which is used by the UK energy switching provider TheLabrador https://kb.thelabrador.co.uk/troubleshooting/how-do-i-install-the-labrador-home-hub

These types of devices use Zigbee to talk to the smart meters and Ethernet or WiFi to link to the customers home network.

If PurePlanet is using the Geotogether Trio II Touch IHD this can also act as a CAD since it has the (option) of including a WiFi module. See - https://www.geotogether.com/products-services/tempo-smarter-energy/

So it seems the hardware side of things may already be solved and this leaves just the software side. Ideally the Geotogether Treo II would have an API via which a customer could access the data. I get the impression it might also have the option for the Treo II to upload data to some cloud service which in turn might be accessible by the customer via an API. (Rainforest's Eagle-200 offers both local API access and cloud access.)

Apparently Geotogether do already provide an API for accessing their devices/data. See the link on the same page I listed for them above.

Could Pureplanet tell us what their current and future plans are in this area?
Is Pureplanet providing the Treo II Touch as standard?
I presume we can assume the Treo II Touch is SMETS2 compatible?
Does the model provided by Pureplanet include the WiFi module?
What sample rate does the Treo II Touch use? That is how frequently does it update the figures, the more frequent the more accurate the information you could see but equally it would cause more work by the Treo and drain its batteries faster - since it has the option of USB power this is not a concern to me.

No, we don't provide the 'touch' version. Ours has buttons.

Does the model provided by Pure Planet include the WiFi module?


The model we have is WiFi compatible, but needs an additional component added to a slot at the back of the device. This can be retrofitted for Members who want it. But this isn't something we'll be looking into until we're well into smart meters business-as-usual and they're in the hands of several thousand PP Members.


What sample rate does the Treo II Touch use to update figures?

For electricity, every 10 seconds.
For gas, every 30 minutes.

Hope that's been helpful!

​The wifi module is quite important to a number of members here, please will you schedule this part of the query for an update with more details as things progress?

Hey @woz
Yep, the plan is to get the basics done first, get smart meters into 'business as usual' (shoot me now 😂)
We know some Members are keen on this more advanced techie stuff.
@Marc

Ok, I found the Geotogther manual for the Trio II and as far as I can see the following applies.

1. They both have the same (attractive) user interface
2. They both seem to support the same WiFi module
3. Logically both will support the same API

In other words the button version will be in theory equally able to act as a CAD in the way I want.

However the lack of the WiFi module as standard will make life more difficult. Apart from the extra cost to me I suspect getting it as a mere end user will be a lot more difficult as Geotogther mainly sell to providers like Pureplanet rather than end users.

Could Pureplanet be able to act as a 'reseller' for them?
@woz @Marc
Could you post pictures of the smart meters you are now installing?

I am considering buying an energy monitoring system which monitors gas usage by using an optical or magnetic sensor to capture information from the gas meter. However it may not be compatible with some types of meter.

This is one for @Marc and/or members who are early adopters, I'm only responsible for starting the thread, but if any of the early adopters want to post a photo of their meters all welcome (obscure any serial numbers though).

​Just a thought...Will the type of meter vary according to which DNO area you're in?

ahhh thanks Duppy, maybe we can get one person from every DNO area to post a photo...(if that's what defines the difference?)

Hey @woz
Sorry for late reply. I had to check this one....
The answer is no, the DNO doesn't have any impact on meter type.
(There are some meters that seem to work better in the north region or the central/south region. We, like other energy companies, are finding this out!)
@Angelabikerbabe @Duppy

Thank you both for your pictures. It would seem they both and presumably others all use LCD displays for the figures for both gas and electricity. I get the impression that this type of display does not work with the Smappee gas monitor. (The Smappee electricity monitor would work as this is a standard clamp on the power cable and does not try to read the meter.)

So for anyone else interested in trying to have an automated energy monitoring system the best approach is going to be my previously mentioned CAD approach.
Hi, since my smart meter installation the IHD has only ever connected to the gas mater. Even when the engineer was showing me around the IHD it wasnt working and he advised it was something that needed to be done at the pure planet end to get it configured. It's been 3 weeks now so I'm guessing something is amiss. What's my best approach?

Thanks

Hi Chi3f,

I heard that there are industry glitches not necessarily down to Pure Planet affecting signals in certain areas.
But don't listen to me because I could be wrong.

In the first instance best to contact PP directly and get the members service team to advise current situ.
So advance to the APP - open help - open ask wattBot - first type "Message the Team and post your question.
Look back in the APP in couple of days for a response, may be sooner but its the weekend.

Marc the community manager regularly provides updates on smart meters so there maybe something of interest to catch up with. Plus theres some interesting exchanges between Mr Smart and other members regarding this topic, so have gander at these posts.

Good luck, look out for more feed back and enjoy the sun

Hi @BigChi3f
I've just posted over here about the IHD issue being reported by some Members. It's got some useful troubleshooting tips, and also how to let us know if it still doesn't sort it. 🆙
Is the comms hub on the network side of the meter? Ie the customer doesn't pay for the electricity it uses?

I can only suppose it's on the supply side because it would revert to battery if the power was cut, but that is a wild guess.I think Mr Smart should supply a circuit diagram or block schematic:p then we can look for ourselves...

Is there a way to extend the IHD as the meters are reasonably far away and it can't connect with them from our flat, unfortunately.

hi thisperson
There may be solutions but my take on this is it's down to the installers to make sure you have a properly working system. Walking away without offereing you some form of solution or help is unacceptable (of course there may not be a solution...)
My advice is to put in a request via help for the installers to come back and find a way to fix it so it works (if there is a viable solution, perhaps configuring the transmit power or even a wired extension - who knows...)
Go to help in app or online , type message the team and ask. Please will you keep us updated? This is interesting.

The IHD and Comms Hub and Meters all communicate using the Zigbee wireless standard. With Zigbee each device acts as a repeater for others and forms a 'mesh' type network topology. However in this case the number of devices is small and all but the IHD are likely to be in the same single location so this does not help in terms of extending range.

In a normal Zigbee setup it would be possible to get a dedicated Zigbee repeater although most people get a simple and very cheap Zigbee smart power socket like this - https://www.ikea.com/gb/en/p/tradfri-wireless-control-outlet-00364477/

I believe this still may not help in this case because I believe all the Zigbee devices need to be configured as part of the same 'network' and you would not be able to add the standard Zigbee device to the smart meter network. Perhaps PurePlanet can confirm this.

So, it seems hypothetically it would be possible but it might require the smart meter manufacturers to make a Zigbee repeater that can be officially joined to a customers smart meter HAN - Home Area Network. I have not been specifically looking but I strongly suspect that no such device yet exists.

Since likely many customers will have this problem I feel that the manufacturers need to address this and provide such a repeater solution.

Note: For security reasons the HAN used by smart meters only accepts devices that have been officially 'white listed' so generic Zigbee devices cannot be connected. They are supposed to allow the customer to connect their own devices as long as they are white listed, despite this some providers have been uncooperative and this is regarded as being in breach of the licensing terms for smart meters. (The whole point of smart meters is to facilitate connecting customer access devices.)

@Marc I hope Pureplanet are going to be more cooperative about customers wanting to connect CAD type devices. Some customers have had to take OVO Energy to OFGEM and BEIS to get them to behave properly.
On the IHD reset device option does this take the device back to the point after engineer set up?
