evohome HCE80 UFH valve state decoding from radio signals

**bruce_miranda** · 20th January 2020, 12:56 AM

You definitely have a problem with your radio and it's firmware. This log has some Heat Demand but again only for 1 UFH controller and only for 1 zone within it.

@springgreens I recommend trying the 'fifo-hang' branch of the ghoti57/evofw2 firmware as this is the current active development branch. I've been testing it over the weekend with pretty good results. As Bruce has mentioned, there's definitely a problem with the firmware processing exactly the HCE80s message that you need.

@DanD I also just tried the 'fifo-hang' branch. Zone demand data seems to be coming through fine on the HCC80R with this as well, but sending is no longer working for me (arduino nano). Rolling back to the original fifo firmware, and sending works straight away.

Is sending working correctly for you?

@smar Thanks for trying out the fifo-hang branch and confirming that it receives the HCC80R demand messages OK on your system. With regards to sending, no it's not currently functional on this branch.

Thanks. I'll try the fifo-hang firmware. But will be later in the week

Ok thanks for the confirmation.

Here's part of a log fom evohome-listner script running with ghoti57/fifo-hang branch (but I had to add spi.c to the Makefile and #NEEDS_MAIN to sha_nano_v3.h)
I've got plenty more logs but am getting php errors trying to upload - so a small part spread over 3 posts...

The evohome config
{
"01:062953": { "name": "Study", "zoneId" : 1, "ufh_zoneId": 2, "zoneMaster": true },
"30:071715": { "name": "evoGateway", "zoneId" : 240, "zoneMaster": false },

"03:125829": { "name": "Garden room", "zoneId" : 3, "ufh_zoneId": 1, "zoneMaster": true },
"03:125833": { "name": "Shower room", "zoneId": 5, "ufh_zoneId": 1, "zoneMaster": true },
"03:256078": { "name": "Ensuite", "zoneId": 7, "ufh_zoneId": 3, "zoneMaster": true },
"03:255827": { "name": "Hall", "zoneId": 4, "ufh_zoneId": 0, "zoneMaster": true },
"03:256140": { "name": "Lounge", "zoneId": 6, "ufh_zoneId": 2, "zoneMaster": true },
"03:125827": { "name": "New bedroom", "zoneId": 8, "ufh_zoneId": 4, "zoneMaster": true },
"03:255832": { "name": "Bay bedroom", "zoneId": 12, "ufh_zoneId": 3, "zoneMaster": true },
"04:146232": { "name": "HBedroom", "zoneId": 9, "zoneMaster": true },
"04:146262": { "name": "HDayroom", "zoneId": 10, "zoneMaster": true },
"04:160544": { "name": "HBathroom", "zoneId": 11, "zoneMaster": true },
"13:233522": { "name": "evoHeatDemand", "zoneId" : 252, "zoneMaster" : false }
}

As far as I can tell the conclusion is that HCE80 doesn't transmit individual zone actuator demands, or at least we haven't so far worked out how to read them.
Pls let me know if you think otherwise, you need more logs or different radio firmware trials. I'm very happy to support wider efforts to decode evohome radioeven if we can't figure out indiv zone demands!
