This is bizarre and for ages did not realise /and so kept altering stuff!
I have created a template entity by adding 2 entity values together. I get the result I want.
When looking on a history graph it shows the result, changing with time. No shocks
Everywhere except the I-phone companion app this entity shows as null, but it shows as a figure in the app. But it still shows in the history?!
This gets really weird when I put this into a Sankey chart( great integration) as this only shows the section for this entity when on the I-phone companion app!
The entity has a unit (Wh), is call sensor.grid_to_house
Is this a reserved name or something?
I’ve checked using ingress, duckdns,direct Ip, every browser I have installed and even on my I-phone it vanishes when using a browser.
Any ideas?
