Hi

I have the prehistoric-looking Duet II, originally supplied by NPower. Sometimes during the day I notice one of blue segments in the gas part of the display lit up, indicating I'm using gas. However, this will usually be when I'm sat working, with the heating off, cooker off etc.

Does anyone know how long the segments in the display would stay lit up, ie how often they refresh? It's possible it's staying on a very long time after I run a hot tap and I just don't notice for a while, but I'm concerned my smart meter is thinking I'm using gas when I'm not.

I know the electricity part of the display refreshes pretty quickly after I turn something on or off, but the gas part does seem to be lit a very long time after any possible gas use.

Thanks

If a Duet II is an IHD then maybe @theunknowntech can answer your question.

Ah yes, the Geo Duet II IHD, I know it enough to answer this.

For electricity, it refreshes every 10 seconds, for gas it's roughly every 30 minutes. This is because the gas meter only checks in with a heartbeat once every 30 minutes and it's not possible to get a refresh in between each heartbeat.
