Hi,
you state in the README that with autodiscovery you cannot impose limit on discovered entities, It's not really correct.
I was able to impose limits and steps in Ebusd Mqtt discovred items with the customize option in configuration.yaml in HA
customize:
number.ebusd_energymgr_z1_heat_offset:
name: Z1 Heat Offset
min: -7
max: 7
step: 1
mode: box
You need obviously to do it for every single input entity but it's a minor problem,since I've noted that a single error in inseting data in HA can result in handling error of the command by ebusd/remote controller/energy manager.
Hope it helps
Hi,
I've just tested your brute force error discovery script, I was able to dump these correlations:
1=102;2=1P1;3=1P2;4=1P3;5=104;6=107;7=1P4;8=1P4;9=109;10=110;11=112;12=114;13=116;14=118;15=103;16=105;17=106;18=108;19=111;20=1P5;21=1P6;22=1P7;23=1P8;24=201;25=309;26=203;27=308;28=205;29=000;30=2P2;31=209;32=301;33=303;34=304;35=000;36=306;37=000;38=110;39=112;40=122;41=123;42=311;43=312;44=5P6;45=501;46=502;47=504;48=5P1;49=5P2;50=5P3;51=5P4;52=601;53=602;54=604;55=605;56=607;57=421;58=000;59=610;60=612;61=6P1;62=6P2;63=611;64=000;65=422;66=510;67=753;68=750;69=603;71=511;73=3P9;75=620;76=621;79=752;80=976;81=972;82=973;83=974;84=975;85=978;86=979;87=980;88=981;90=974;91=755;92=944;93=945;94=946;95=140;96=1P9;97=141;100=701;101=711;102=721;105=411;112=962;113=9P9;114=990;115=971;116=970;117=961;118=960;119=2P8;120=901;121=902;122=903;123=904;124=905;125=906;126=907;127=908;128=909
my boiler manual (Genus One 30) reports other error codes that should be available eg. :
801 Richiesta Taratura Automatica (Auto Calibration needed) 802 Taratura automatica non riuscita (Auto calibration error) 803 Sttaggio parametro 229 errato (Wrong setting on prameter 229 - boiler nominal power) 804 Richiesto clip-in disaccoppiatore bus801 Richiesta Taratura Automatica 802 Taratura automatica non riuscita 803 Sttaggio parametro 229 errato (potenza nominale caldaia errata) 804 Richiesto clip-in disaccoppiatore bus (Bus decoupler clip-in required)????
is it possible that the scripts tests only the first 128 error codes but my system has more "error slots"? Can I modify the script to test also 129-256 errors or I'm I risking of writing gibberish things on the bus?
TY
Force a bus reset with the following command:
~/ebusd/build/src/tools/ebusctl hex fe203400
The boiler restarts, and the packets concerned have the following commands: 2031, 203a, 2036.
To listen to the packets coming from the boiler, don't do anything special, just read the logs generated.
To listen to packets coming from the thermostat or any other device connected to the bus,
replace the TX wire with the RX wire from your adapter/mcu (leave the TX wire disconnected, as it's useless in this case).
=> in other words: put the RX line of the adapter/mcu on the RX line of the boiler.
Specify the type of equipment you have and, if possible, the exact product reference...
Addresses src/dest (or emitter/receiver) of devices on the bus:
ebusd: 31/36
boiler: 37/3c
thermostat z1: 70/75
thermostat z2: f0/f5
thermostat z3: 01/06
Boot time:
boiler: 13.5s - 13.57s; 12.7ms/packet
thermostat: 16.2s - 16.4s; 11.8ms/packet
Handshake sequence is divided into the following parts:
Addr not found in boiler boot sequence but present for thermostat:
[
'04', '05', '06', '08', '0c',
'14', '15', '16', '18', '1c',
'24',
'35', '36', '38', '3c',
'44'
]
=> some logic here...
Special packets (boot from offline and reboot):
