Hi Schelte,

I've got an issue with RR command:
RR=1 produces Read-Data request instead of required Write-Data

Sent by gateway - no success

Code: Select all

13:15:11.301203  R00040100  Read-Data   Remote command (MsgID=4): 1 0
13:15:11.410079  B70040000  Unk-DataId  Remote command (MsgID=4): 0 0
Sent by thermostat - success

Code: Select all

13:40:46.474844  T90040100  Write-Data  Remote command (MsgID=4): 1 0
13:40:46.589125  B500401FF  Write-Ack   Remote command (MsgID=4): 1 255
could you please update firmware to send Write-Data request for RR command.

As side effect MsgID 4 marked as unknown after unsuccessful read request and I can't reset error from thermostat (

Firmware version is 6.5
Boiler - Baxi NUVOLA DUO-TEC+ 16
Thermostat - BAXI 7 DAYS PROGR.TIMER WIRED (7104336--)

That definitely looks like a bug. I'll investigate.

Hi Schelte,

I would be very grateful if you could provide the fix at your earliest convenience. I am ready to test it any time.

Thanks a lot for your time, help and support.
Mike

I already made a fix. I didn't realize it was that important to you. Please try the attached firmware and let me know if that works for you.

Schelte,

yes, it's working. You made my day ) I don't need to drive 100 km to reset the boiler (joke, I can ask my neighbour).
Thank you very much.

Are there any other changes which I can test?

Thanks for the confirmation.

The other change (6.5.1) only has effect with boilers that support MsgIDs 93, 94, and 95. For those MsgIDs, the OTGW will read all characters following a PM command.
