    sorry should have been clearer, i'll like to see the System Summary page of the controller on a HCE80. Because if that can show the individual zones' heat demand, then we can try and work out how. But if that can't or is showing all the heat demand for the controller against 1 zone, then we have to conclude that the HCE80 does not request Heat Demands from the controller individually but instead sums them up and sends them as a single heat demand for the entire controller.

    I think we're seeing a difference between HCE80 & HCC80
    I have 2 HCE80 and see no 02:xxxxx 3150 message. All I get from 02's are 0008 messges like these...

    2020-01-25 12:58:09: 1: RELAY_HEAT_DEMAND --- I --- 02:023727 --:------ 02:023727 0008 002 FC00

    I only have 3150 messages from the controller and TRVs, like these...

    2020-01-25 13:02:34: 1: ZONE_HEAT_DEMAND --- I --- 01:062953 --:------ 01:062953 3150 002 FC7A

    @smar, I think you have the HCC80?

    @bruce, I can confirm that the controller system summary page does *not* show individual UFH zone demands. Only a % for the first zone on each of the HCE80s (and the boiler relay and each of the TRVs)

    And there's me thinking the 'E' in HCE meant 'External aerial', not 'Economy version'

    @smar, in case you were wondering, evohome-listener returns below in the events.log

    2020-01-25 13:02:28 | | ERROR | 'list index out of range' on line 564 [Command ZONE_HEAT_DEMAND, data: '--- I --- 02:023727 --:------ 01:062953 3150 002 0372', port: 1]

    No surprises as you'd not seen HCE80 msgs before. Only confusion for me is that I see no 02: 3150 messages in evogateway.log. I'll add more logging and report back

    I added another log to the evohome-listener script to record all radio message before any processing and can report that I do have 02: 3150 messages, but only with a short payload.
    Here's a dump of the raw 02: messages

    I'll try to correlate these 02: 3150 mgs with the UFH zone lights to see if the individual zone actuator states can be inferred in some way. It's take a while though.

    Yes, the HCC80R.

    Could you open an issue on the github page, and also include the relevant lines from the raw log file. Also that error line number doesn't seem to be correspond to the current code. Can you try with the current version.

    Thanks.

    if the controller cannot show the individual zone heat demands, then I don't think its possible. This thread could serve as a good pointer who anyone else who has a choice between the HCE and the HCC.

    FYI I posted a bug report to Honeywell along the lines that the 'Summary Info' screen isn't working for me. Will let you know what they come back with.
