Getting S0 output ftom a Smart Meter


At my request I recently had a smart meter installed, a model chosen by my energy provider (Green Energy), an EDMI Mk7C http://www.edmi-meters.co.uk/mk7c-smart-electricity-meter/ with (at my request) a S0 output. BTW, I paid for it!


Chap who turned up had no idea about why it was being fitted and said he didn't have the software on his laptop to configure it but it should work. As the S0 socket was inside the sealed part of the meter, he ran a cable to a junction box. From there I ran a high quality CAT6 cable to my Solar Log 200 (see my intro post - opens new window).


First attempt at connection produced a load of data corruption which appeared to be a combination of old firmware and problems at the Solar Log cloud system. Had to recover everything. Second attempt today seems a little better. The cloud system is showing today's data (opens new window) but the historic data needs manually reformating which will I'm told take a few days - they assure me the data has not been lost!


Problem is no consumption data is being displayed and the Solar Log people say that no S0 feed is being received as can be seem on the cloud graph (status: run, offline).


Before calling my energy supplier it would be good to check the presence of a signal. Somewhere I have a digital pulse detector (if I can find it). Would that work? Maybe I should contact EDMI. I want to avoid being charged for a call out when the problem is not the smart meter. The smart meter has a mobile sim card. Maybe they can do a remote check and configuration.


Ideas welcome Thanks


Alan


PS the smart meter was meant to come with a remote display unit but after waiting months for them to come from China it turned out they were not up to the required quality. So I said go ahead and fit without.

Getting S0 output ftom a Smart Meter


Hi Alan.


I am also with GreenenergyUK. I got my EDMI smart meter only because I asked to go onto a split-rate tariff.


The tariff has been extremely beneficial - see http://www.microgen-database.org.uk/gallery/smart-meters-solar-usage-export?pn=1 ‘Split-Rate Consumption Tariff’ ‘March Bill’. By the end of the summer, I'll have recouped the cost of my Smart Meter from the tariff savings - honest.


Unlike myself with my Solar PV split East-West that virtually shuts down for winter, you'd likely benefit in winter months too.


These smart meters can be remotely reconfigured for these things, and I find Edd Horne at GreenenergyUK quite helpful, albeit being dependant on the G4S meter supplier.


regards,
Roger










Economy 10 tariff provides 6.9p/kWh off-peak import between 12am-5am, 1pm-4pm and 8pm-10pm; http://www.pvoutput.org/aggregate.jsp?id=21047&sid=18934&v=2&t=m on approx. 63% off-peak usage, 22% solar usage, and 15% peak-rate usage.
1,900kWh annually is exported, mostly in summer, on approx. 3,200kWh generation. Approx. 4,500kWh/year is imported, mostly for (a) winter and springtime off-peak Storage Heaters, and (b) off-peak hot water Immersion heating (which is “dumb”, i.e. not linked to the solar PV).
PV array is split East-West. Income is from Phase II 21p/kWh Feed-in-Tariff plus smart metered 3.2p/kWh Export Tariff.

Getting S0 output ftom a Smart Meter


Thanks Roger


I must say that I find Green Energy very customer friendly and helpful and that includes Edd. I've been dealing with Chris and Sam on this Smart Meter.


Just looking through my old emails I see Sam did ask if I need the engineer to call but also asked if I can confirm the S0 output myself. If they send an engineer they need to know why they are attending and have the right knowledge. Installer was imserv.com


I'll email GE.


Alan

I don't know how you got on with this Alan, but it was Edd at GE that helped me so much. Anyway, I've now enquired with GE about a Gas Smart Meter for pairing with my EDMI Mk7C ‘leccy Smart Meter. It seems to me equally potentially useful to have some real-time monitoring of your heating fuel too, and with an online viewing portal.


In case I don’t get a satisfactory reply, does anyone know which suppliers provide PAIRED Gas Electricity Smart Meters?

Getting S0 output ftom a Smart Meter


I've been busy with other more important things and this has taken a back seat.


As mentioned, after connecting the smart meter and configuring the Solar Log system all my historic data on the cloud was corrupted. Solar Log eventually sorted though I lost the low level data from year one, just had the daily yield. They are now trying to interest me in the latest consumer model that allows management of electrical devices - something I was thinking of using a Raspberry Pi to do as a project.


Still, the Solar Log graphs are not showing consumption. Not sure if it is the Smart Meter, my wiring or the Solar Log.


I did send a couple of emails to GE but nothing has happened.


Meanwhile I've switched my gas supplier to GE (active from tomorrow), so a gas smart meter is of interest.


Regards


Alan

Getting S0 output ftom a Smart Meter

Success!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Well I've had another go getting the Smart Meter S0 output read by the SolarLog 200. I spent many months (6?) liaising with Green Energy and they in turn the electricity supplier and they in turn their installers on top of emails to the EDMI re their smart meter Mk7C and to SolarLog in Germany.

Eventually the engineer came, unbriefed and without any equipment to test the S0 output. After 1.5 hours on the phone said the meter was OK and it must be the SolarLog. SolarLog were of course saying their SolarLog was OK and I was using an unapproved (by them) smart meter (Hobson's choice as Green Energy only offered the EDMI). S0 standards say this should not be an issue but reality can be different.

So I signed up to this forum https://community.openenergymonitor.org/ and asked for help. A kind Robert Wall in the USA suggest making up a circuit tester. This proved that the Smart Meter was generating the S0 pulses (couldn't check if they were of the correct 30-40ms duration). It also proved that there was no voltage across the SolarLog S0 input socket pins 1 and ground.

It then occurred to me that I may have wired the plug incorrectly. The SolarLog manual merely states to connect the Smart Meter +ve to pin 1, the ground to pin 2 and to bridge pins 3 and 4 and leave pins 5 & 6 unconnected. In the absence of any diagram or markings on the SolarLog, other that a label to the left end of the socket saying “S0”, I wired the plug presuming the pins are 1 to 6 from left to right.

Today when I asked SolarLog if this is right they replied “No, the pins go right to left” - needless to say I'm fuming with them and myself for making what seemed to be a logical assumption. I had even sent SolarLog a photo of my wired plug and they didn't pick it up!

*******************************************
So for any users of SolarLog 200 (and no doubt other models in the range) the S0 socket pins read from the left: 6,5,4,3,2,1
*******************************************

I attach the SolarLog Cockpit display taken this evening with zero generation and a 3Kw immersion temporarily switched on.


Now to move on to another project: A Home Monitoring system to monitor humidity levels in the loft - since improving the house insulation we've had occasional condensation in the loft when there has been insufficient cross winds to ventilate through the sofit vents. Rather than installing roof vents (expensive work) I'm going to monitor using a Raspberry Pi and if high humidity then switch on extractor fans. Once working the system could be used to monitor and control other things as well.
