Where / how are the 'Data' formats defined for the values displayed on the Devices page?

Hi,

I'm trying to extend the Domoticz code for the Evohome system and I'd like to add an additional value to the Evohome Heating/Temperature devices which currently have their data defined as Temp;Setpoint;Mode. I've succeed in adding an additional sensor value within the database so I now have values with the structure Temp;Setpoint;Demand;Mode, but I can't work out how or where the display formats are defined for the information shown on the Domoticz Devices page. For example, the stored value '18.5;20.2;Auto' is displayed on the Devices page as '18.5, (20.2), Auto' and if I display my new record '18.5; 20.2;200; Auto' it appears on the Devices page as '18.5, (20.2), 200 until Auto' as the format assumes that my additional value is part of a datetime record.

Thanks,
Dan

I've started to realise that my previous post was a pretty dumb question as there seem to be far more linked attributes to a device than I intially realised. I've been focussing purely on the Domoticz C++ code and wrongly assumed that I could extend device definitions within this code. However, I decided to have a play with JSON queries of the new data records that I'd inserted and I realised that these queries also rely on the original database structures.

If I wanted to extend/modify a device definition in the Domoticz database to add in a new data item, where should I start? Should I submit this in the suggestions forum? As mentioned in my previous post, what I'm aiming to achieve is to extend the Evohome sTypeEvohomeZone device to add in a 'Demand' value which captures the current heat demand.

Thanks,
Dan
