What does the pylon symbol mean on my Chameleon In-Home Display (IHD) 6?

Thank you, sorry i am new to this and of course its the in home display that i was referring to. Could you possibly tell me if its normal to not be able to see how much my usage is per hour while the pylon is showing? Also i can not see how much per hour my gas usage is at all.

Thank you, yes you are right about the display, senior moment.

When you are Exporting, your import will be zero - therefore no cost/hr at that point. 
It can only be importing or exporting, not both. 
For your gas, it depends if the gas meter has connected to the network (it sometimes takes a while) or if your IHD is on the set screen to show that. You can set the ‘home’ screen from the menu on the IHD once the data is live. 
Incidentally, can you see your gas usage on your account page? The info on the IHD for gas only updates every half hour, not as often as the electricity 

so if i understand that right, does it mean that i am still being charged for the electricity that i am using but i just cant see how much per hour? My gas just shows how much i have used so far today, not per hour, so difficult to see how my heating costs per hour so i can limit it. Also my meter was fitted on 24th Jan, but the readings are a bit erratic, in as much as one day when i used a lot of different things like power washer, washer and dryer power tools etc, and my usage was £4.06, but on another day i was out all day and didnt use anything and the usage was £6.76. It just all seems very confusing

Not exactly @Cazbob . If your system is exporting then it is supplying what the home needs at that point meaning that your import is zero .. costing zero at that point. Your electricity usage will depend on the sun on each day so you will see quite a change depending on the weather. 
Gas is not as flexible in reporting. The meter is battery powered for its data and so it doesn’t show in the same way. 
Also if you have gas heating, presumably that will depend significantly on the outside temperature and so will vary a fair bit. 

So, and im so sorry if i sound thick, on a dull day i am paying for all usage, but on a sunny day i am not? please accept my apologies for not getting it and i totally understand if you dont want to answer. i prob make it very hard for you, not intentionally. 

Not a problem .. we’re here to try to help. 
Thats the thing with solar, when the sun’s out then the panels will supply quite a bit of your usage (so you won’t pay for that part), without battery storage of course, you will pay for overnight and similarly you’ll pay for more on a dull day. 
Hope that helps

Just another thought @Cazbob , I’m not sure what systems they fit (manufacturer and type) but there should be a monitor for your solar inverter. If you get a view of that, it can show you the variations during each day of solar generation and home energy usage. 
Mine looks like this at this point today 

I also have graphs for each day and summaries by day and month

oo thanks, i will get other half to look for that, not seen anything myself though

thank you, its getting clearer, a tad lol. i am almost 70 and it takes a bit of getting in this old head lol. but thank so much for your help
