Good evening @Mclacr ,

Thanks for bringing this up. We just need one more thing to help us answer this one, if you’re up for it. Please post photos of your setup so we can see exactly what you’ve got. If you’d rather not, let us know and we’ll work with what we’ve got here.

Thanks!

Thanks, I hope this helps. I’ll have a go at a wiring diagram if needed. 

The pictures are very helpful, thanks.

We’ve seen this sort of meter before, but with a Landis + Gyr contactor for the offpeak circuits bolted on to the meter itself, like this:
  

You have a separate one which ought to behave in the same way. The meter sends a signal at the appropriate time (down the thin blue cable) to the contactor to switch the power on and off to your heating equipment. 

It sounds a bit unlikely that the switching time varies from day to day; the times should be set in stone inside the meter itself. If you can document the times the circuit switches on and off (the two daytime slots would probably do), you’d have some evidence for the smart team to examine. 

The switching times should coincide with the tariff changes to avoid not intentionally powering up heaters outside of offpeak hours. There may be a built-in delay to make sure you’re on the cheap rate before the heating switches on; with six switching times, this could add up to perhaps half an hour. If the times are very different, something’s not right. Get your facts together - along with the photos - and then get in touch with Support.

You can always run other equipment at the cheaper rate - washer, dryer, hoover, for example - from the start of an offpeak period regardless of when the heating is turned on.

Thanks @Firedog it has been hard to catch the times but I can try harder. I’ve got alarms set for the published times and I can set up a lamp where I am in the house so I can log when off peak switches. At the moment I know I’m an hour short each day on off peak. 
thanks for the tech help. It’s helpful to have how I thought it should work confirmed. I’ll do some logging and get on to support and report back.

Hey @Mclacr 

I’m really glad to see a couple of our volunteers have already stopped by with some really helpful advice already.

Firedog has given you a nice little timeline to follow of getting your information together along with photos, so if you do a closer check and take all your info to the Support Team they’ll be able to help out better, they’d ask you to do all of this anyway so it’s a good thing Firedog has already let you know to do this.

Let us know how you get on with everything

Thanks @Abby-OVO
