    Interesting "hack" you are using...

    Yes, the reheat time does seem to be too high for an effective hot water priority solution. I have been running without hot water priority since the system was...

    Thanks and yes, makes sense. Not really sure if our cylinder would be classifed as a quick re-heat - it is an unvented OSO Powercyl Delta Coil, installed last year. Normally takes about 45 minutes...

    Yes, I do have the separate zone valves/BDR91s, though I had previously disconnected the one for raditators, and left it in the open position (it had started to stick - even though it was only about...

    Yes, that is what I had figured. Assuming that I don't have hot water priority, then I'm guessing that some of the benefits would be negated?

    Great, thanks. As you've had your OT bridge in place for a few years now, is it something you would recommend based on your experience (I have a Vaillant condensing system boiler, and my DHW is also...

    I've been thinking about adding OpenTherm to my setup. What problems are you encountering with the OT bridge? Is there somewhere where you are discussing this?

    Thanks.

    I am using an arduino/CC1101 to monitor the messages and simply don't see messages from the CS92A when it stops working. If the issue was controller related, I would have expected the messages to...

    I'm using the insertion sensor and have the same issues described here. In fact, as advised by Honeywell, I have also put in thermal paste into my cylinder's insertion point, to aid thermal...

    No, I didn't try that one. May give it a go at some point but as per @DBMandrake, I also think that there is an inherent design issue with these units.

    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...

    I don't think the update frequency changed with lower differentials for either of the senders. The lower differentials just meant that as and when a measurement was finally sent, evhome would start...

    Ok thanks for the confirmation.

    @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...

    That's actually the way I've done the script - when sending messages, it sends it from that 30: id, so that the evohome controller thinks it is getting a valid instruction from an internet gateway.

    I recall when I was testing with one of ghoti's firmwares (I think the master) I wasn't receiving any messages from my HCC80R. Switching to the other fifo branch, the messages immediately started...

    Here is a random 20 minutes of data from my system, filtered so that it is only showing the HCC80R messages:

    This should already be decoded in the evohome listener script. Are you not seeing it or have I missed something? I am getting zone by zone UFH demand from my HCC80R (02: device) via the listener...

    Sure. Do you mean the "evohome HCE80 UFH valve state decoding from radio signals" thread?

    Not sure what else to suggest without further investigation. Maybe as @Dan says, the HCE80 is just not sending the individual zone data. Have a look at the "raw" data in the separate log file and see...

    I just realised that I hadn't spelt out the devices.json file structure in the github README with the correct nuances for the HCC80R UFH controller.

    The HCC80R messages seems to send it's own zone...

    Not that I am aware of! I haven't really publicised the script, as it was put together for my own needs. I also started off simply wanting to "listen" in to the radio messages, and log them/process...
