Help requested: any Evohome users with an RFG100 and a HGI80?

Post by DanD » Tuesday 21 March 2017 14:10

Hi,

I'm working on a prototype of code to perform some of the functions of the Honeywell Evohome controller and I need some help with tracking down the exact structure of the commands to request and update the daily setpoint programs for each zone.

To do this I think I need the help of someone with an Evohome RFG100 and a serial device, a HGI80 or equivalent (RFBee etc). They'd need to use the Evohome phone app to make a change to a daily setpoint for one of their zones and then capture the commands that the RFG100 sends to their Evohome controller using the serial device. You shouldn't need to mess with your Domoticz set-up to achieve this. Hopefully, just using a serial client connected to the HGI80 should be sufficient.

Thanks!

Actually, since today I have both (and an Evohome). I am just changing to the RFG100 because I couldnt get it working stable (on a raspberry).

Glad to help, although I am not sure how and if I could, but willing to try.

I got the WiFi version and the HGI80 if it helps.

What are you trying to do?

Hi both,

Thanks for your replies. What I'm trying to do is to fully understand the structure of the messages that the RFG100 sends to the controller when specific changes are made to scheduled setpoints. To be able to do this you'd need the non-wifi controller, a RFG100 and a HGI80 or similar serial device (to capture the messages). In particular, I'd like to capture the messages that are sent when the following changes are a made using the calendar functionality in the app:
  • o add a new scheduled setpoint on a day so that it creates an additional weekly setpoint on the controller
    o use the copy function to copy all the setpoints from one day to another
I'm happy to just have the raw serial messages '--- I --- xx:xxxxxx........etc', ie. they don't need to be captured via Domoticz, it can just be via a simple serial client.

I'm currently building a prototype Evohome controller in Python (see my github area) and once I've got this working OK, I hope to be able to add this functionality within the Domoticz Evohome code.

Thanks,

Dan

Hi,

Thanks for your message. I managed to make some progress on this a few months ago as I purchased an RFG100 and another user loaned me a controller, but hit a problem with decoding the complete schedule information. I was hoping to be able to decode the scheduling to enable a full backup/restore function. After some extensive testing I came to the conclusion that the messages must contain some relative date information as a restore seemed to sometimes hit problems and get rejected. I've not been able to do much work on my Evohome code for tge last few months, but I'm now ready to restart. I'll take a look at where I left off and post some further details, probably in a couple of weeks.

Hi Dan,

Any progress on this? I have a HGI80 and hate the fact that to mess with schedule data (rather than just editing setpoints/overrides/modes) I still have to use the 'external' TCC solution. If I could edit the schedule just using the HGI80 I'd be thrilled! Let me know if any beta testing would help.

My current homebrew solution is done in python/perl and uses an Alexa linking to Google calendar to spoof infinite future scheduling rather than fixed weekly scheduling. I retrieve today's desired schedule from Google and then use a perl interface to TCC to update the json data for today's zone-scheduling before rewriting to TCC. Doing this every day means TCC always has my correct schedule for 'today'. I'd much prefer just to do that with my HGI80 and take TCC out of the loop if I could.

:oops: Got me !

I guess I want to future-proof my setup for when Honeywell takes TCC down in a distant future. Hopefully my HGI80 will still be operational then.
