pyhpsu's Issues

Creare directory separate per tool (e.g. pyHPSU) e per gli script (e.g. hpsu.fast.sh, hpsu.fast.service, hpsu.fast.timer)

canpi.py - rendere retry configurabili

Estrapolare dal codice e rendere configurabili:

numero di retry per sincronizzazione (15)

Grazie !

    while notTimeout:
        i += 1
        timeout = self.timeout
        rcBUS = None
        try:
            rcBUS = self.bus.recv(timeout)
        except Exception:
            self.hpsu.printd('exception', 'Error recv')                    

        if rcBUS:
            if (msg_data[2] == 0xfa and msg_data[3] == rcBUS.data[3] and msg_data[4] == rcBUS.data[4]) or (msg_data[2] != 0xfa and msg_data[2] == rcBUS.data[2]):
                rc = "%02X %02X %02X %02X %02X %02X %02X" % (rcBUS.data[0], rcBUS.data[1], rcBUS.data[2], rcBUS.data[3], rcBUS.data[4], rcBUS.data[5], rcBUS.data[6])
                notTimeout = False
        
        if notTimeout:
            self.hpsu.printd('warning', 'msg not sync, retry: %s' % i)
            **if i >= 15:**
                self.hpsu.printd('error', 'msg not sync, timeout')
                notTimeout = False
                rc = "KO"

Canbus Cable

Where to buy a canbus cable tha fits to J13 on Daikin Altherma?

pyHPSU.py - rendere retry configurabili

Estrarre dal codice e mettere in file di configurazione:

il numero di tentativi di retry (4)
il tempo di ritardo tra un retry ed il prossimo (2)

Grazie !

for c in hpsu.commands:
i = 0
while i <= 3:
rc = hpsu.sendCommand(c)
if rc != "KO":
i = 4
response = hpsu.parseCommand(cmd=c, response=rc, verbose=verbose)
resp = hpsu.umConversion(cmd=c, response=response, verbose=verbose)

            arrResponse.append({"name":c["name"], "resp":resp, "timestamp":response["timestamp"]})
        else:
            i += 1
            **time.sleep(2.0)**
            hpsu.printd('warning', 'retry %s command %s' % (i, c["name"]))
            **if i == 4:**
                hpsu.printd('error', 'command %s failed' % (c["name"]))

Lowercase nibble in commands_hpsu.csv

In HPSU.py the logic on "commands" require them to be defined with all nibble uppercase (e.g. if command[6:8] != "FA").

the file etc/pyHPSU/commands_hpsu.csv has a last row with some lowercase nibble

t_flow_cooling;61 00 fa 03 dd 00 00;190;d;10;w

this should be

t_flow_cooling;61 00 FA 03 DD 00 00;190;d;10;w

Supporto python 3 per ELM327

Ciao zanac,
ho avuto problemi nell'uso di python 3 con ELM327 per via della diversa codifica delle stringhe.
ho apportato alcune modifiche (principalmente decode('utf-8')) che mi hanno reso funzionante il tuo script ma sarebbe preferibile se rilasciassi tu una versione compatibile.

Grazie,
fabio

Please add simple example for logger

Hi Zanac, can you simple example for logger to log all the parameter values.

Thank you in advance!

Is the daemon working anywhere?

canpi.py - Inserire messaggio in log errore

I log non includono il messaggio che ha determinato l'errore per cui non si puo' fare analisi.

Aggiungere il messaggio che ha determinato l'errore nel log.

Where to obtain J13 connector

Hi!
Where do I obtain the connector that connects to J13 inside the Rotex control unit?
Thanks!

I'd like to try to connect the Rotex HPSU Compact to OpenHAB, but first want to see if I get CAN working.

EDIT: It seems the connector is already present in the HPSU and is plugged onto the controller board. Next question: How to deal with the terminating resistor of the CAN bus?

Add support to run on Rotex rocon-g1 device

With my HPSU compact I got Rotex rocon-g1 gateway, to run it using Rotex Cloud. I don't like that much, so I tried to check what's inside and found Beagle Bone Black with CAN module.

https://www.heizungsdiscount24.de/regelungstechnik/rotex-gateway-rocon-g1-zur-ankopplung-der-steuerung-an-das-internet.html

I got root to the device and found there Debian

I had to install python from sources to get working as python in packages is outdated. I'm not sure what driver use to get it working?

Need your help to get pyHPSU working with can0 in this device.
