Unable to switch Eltako FL62 or FD62

[andreas-bulling]

I am trying to use this library to switch an Eltako FL62 and FD62 (in the context of Home Assistant) but without success so far. I've studied the corresponding official technical specifications in detail (PDF page 16 and 17) and have assembled packets that, from my point of view, match the specification. Specifically, I create on and off packets using

ON

if self._type == "fl62":
    packet = RadioPacket.create(
        rorg=RORG.BS4,
        rorg_func=0x38,
        rorg_type=0x08,
        destination=self._destination_id,
        sender=self._sender_id,
        COM=1,
        LCK=1,
        SW=1)
                
elif self._type == "fd62":
    packet = RadioPacket.create(
        rorg=RORG.BS4,
        rorg_func=0x38,
        rorg_type=0x08,
        destination=self._destination_id,
        sender=self._sender_id,
        COM=2,
        LCK=1,
        SW=1,
        STR=1,
        TIM=0.5,
        EDIMR=1,
        RMP=127,
        EDIM=bval)

OFF

if self._type == "fl62":
    packet = RadioPacket.create(
        rorg=RORG.BS4,
        rorg_func=0x38,
        rorg_type=0x08,
        destination=self._destination_id,
        sender=self._sender_id,
        COM=1,
        LCK=1,
        SW=0)
        
elif self._type == "fd62":
    packet = RadioPacket.create(
        rorg=RORG.BS4,
        rorg_func=0x38,
        rorg_type=0x08,
        destination=self._destination_id,
        sender=self._sender_id,
        COM=2,
        LCK=1,
        SW=0)

Switching the FL62 simply doesn't work for some reason. For switching on the FD62 I see the following error message in the logs although the EEP XML description shows them:

These are the packets that are being put together:

Let me ask the stupid question first: did you perform a teach in between the sender and the receiver?

[andreas-bulling]

yes, I can toggle both when plugging in the USB dongle to my laptop and teaching in/testing using example kipe code that I found in one of the Home Assistant forums. That code uses RORG.RPS packets but setting the dimmer doesn't work with these AFAIK and, according to the specs, RORG.BS4 should also work...

[andreas-bulling]

... base id of my dongle is [0xFF, 0xE3, 0x01, 0x80] and I've tought in using 0x81 and 0x82 ids (see above)

[zpfvo]

Did you do a 4BS teach-in? The process is different to RPS.

[andreas-bulling]

No, I didn't... :( how is it different? With the special packets that are mentioned in the specs?

[zpfvo]

Yes,

on page 19

Now I remember, could be, that Eltako has a special telegram that needs to be sent. There is a PDF out there in the internet that describes it.

[andreas-bulling]

Thanks a lot for the hint - I will look into this and report back ;)

[andreas-bulling]

But do you know why I see that error message? This should be unrelated to the teach in - is this a bug in the code?

[andreas-bulling]

Alright, I tried this for the normal switch (FL62) and it worked! For future reference, this is what I did (I didn't find a code example from anyone having done this - I therefore hope it will also be useful for others):

command = [0xa5, 0x00, 0x00, 0x00, 0x28]
command.extend(sender_id)
command.extend([0x30])
opt = [0x3]
opt.extend(destination_id)
opt.extend([0xff, 0x0]) 
packet = Packet(0x01, data=command, optional=opt)
communicator.send(packet)

time.sleep(3)

command = [0xa5, 0xE0, 0x40, 0x0D, 0x80]
command.extend(sender_id)
command.extend([0x30])
opt = [0x3]
opt.extend(destination_id)
opt.extend([0xff, 0x0]) 
packet = Packet(0x01, data=command, optional=opt)
communicator.send(packet)

The light switched on and off to confirm and the actor responded with the following confirmation packet
0x01 ['0xa5', '0xe3', '0x1', '0x81', '0x8', '0x4', '0x14', '0xb2', '0x66', '0x0'] ['0x0', '0xff', '0xff', '0xff', '0xff', '0x49', '0x0']

What does the confirmation message mean? '0xe3', '0x1', '0x81', '0x8' seems to be like part of the sender_id that I had used ([0xFF, 0xE3, 0x01, 0x81]).

The remaining problem is now the error message for the FD62 - it prevents me from switching that light. Any ideas on how I can fix this / what the problem is?

[zpfvo]

Could the errors occur when you don't specify all data fields? I think if you dont the library just assumes raw_value = 0

I don't know any further unfortunately. But I got a Eltako FR62 to work with the same profile. So I think yours should be possible too. I build the package with:

data = {'CMD': 'Command ID 1', 'TIM': 0.5, 'SW': 'On', 'command': 1}
packet = RadioPacket.create(
             component.enocean.rorg,
             component.enocean.rorg_func,
             component.enocean.rorg_type,
             sender=sender_id,
             **data
         )

The difference i see is:

• I somehow used 'CMD' and 'command'. I now realize 'CMD' is a mistake (Should be COM), but the command might have made it work
• And I didnt set the destination id

EDIT: You also used the lock command without any time duration. Maybe try with LCK=0 so you dont lock it by accident and that is the reason why it is not accepting any commands anymore.

[andreas-bulling]

Thanks for the suggestions/input. The wrong LCK setting I also noticed before when I suddenly couldn't operate the light with the wall switches anymore ;)

I actually do set all data fields - I copied them over from the EEP.XML file... :/ The FL62 works fine now (see above) - but for the FD62 I can't set the dimmer-specific data fields unfortunately, which are rather quite important...

[andreas-bulling]

This is where the error is triggered...

enocean/enocean/protocol/eep.py

Line 221 in 4ec5cd1

self.logger.warning('Cannot find data description for shortcut %s', shortcut)

[andreas-bulling]

It works! I traced back from the function in which the error message was triggered and stumbled over this line in which the EEP is selected:

enocean/enocean/protocol/packet.py

Line 215 in 4ec5cd1

packet.select_eep(rorg_func, rorg_type, direction, command)

I realised that while command is used here, in contrast to you, I don't set it when constructing the packet. And that, as a result, there is a chance that the wrong EEP was selected (that misses the data types). I added this parameter (copying COM) and - voila it works. I can switch on/off and also setting the dimming value works "out of the box", i.e. with the code from my very first message.

Thank you very much for your help and particularly your comment on the command parameter!

For future reference again, should anyone else encounter the same problem:

Hm - I assume after the latest upgrades of Home Assistant it stopped working (haven't changed anything else) and I see a new error in the logs before the first packet for switching on the FD62:

2021-12-18 16:59:05 WARNING (SyncWorker_7) [enocean.protocol.eep] Cannot find data description for shortcut LCK
2021-12-18 16:59:05 WARNING (SyncWorker_7) [enocean.protocol.eep] Cannot find data description for shortcut TIM
2021-12-18 16:59:05 WARNING (SyncWorker_7) [enocean.protocol.eep] Cannot find data description for shortcut CMD

I have a suspicion that maybe the enocean version is not the most recent (0.60.1). Where can I find the installed dependency? I have HA OS installed - the documentation says "Home Assistant will try to install the requirements into the deps subdirectory of the Home Assistant configuration directory". But the deps subdirectory is empty...
