Same devices - different 433 messages???

Hi all,

I've said in my previous thread - I've got about 20 MD-2018R vibration glass sensors:

(https://www.amazon.co.uk/AtlanticS-MD-2 ... B00FGSG1X6)

MOST of them are picked up like this:

Meiantech/Atlantic/Aidebao:

Code: Select all

Packettype    = Security1
subtype       = Meiantech/Atlantic/Aidebao
Sequence nbr  = 0
id1-3         = CD81AA decimal:13468074
status        = Motion
battery level = OK
Signal level  = 8  -56dBm
Strange - but 4 of them will only show up in RFXmngr when undecoded is on - and are like this:

Visonic PowerCode motion:

Code: Select all

Packettype        = UNDECODED RF Message
UNDECODED VISONIC:12A91240 
They are found in domoticz only when VISONIC is the only mode turned on - you have to turn all others off.

They dont function like the other sensors either when they are added.

Do you think this could be a setting that has been changed by the way the battery was put in/taken out sequence - or does anyone have any ideas why identical devices could be sening out different messages?

Thank you.

Are you sure they use the same hardware inside?

Hardware is 100% identical - I've made an example - device on left will not work, device on right works.

Device on the left just sends a bad message.

Does anyone think this could be fixed? With maybe a sequence of battery removals or something?

(The switches just control sensitivity of device.)

Thank you!

Thanks to b_weijenberg for showing me - that when Meiantech/Atlantic ONLY is enabled in mode - the device is sending out the correct message:

Code: Select all

Packettype    = Security1
subtype       = Meiantech/Atlantic/Aidebao
Sequence nbr  = 0
id1-3         = 5581AA decimal:5603754
status        = Motion
battery level = OK
Signal level  = 8  -56dBm
So does that mean this device has the same ID as one of my lightwave devices or something?

And all others work ok because they have different ids?

Thank you!

Sorry, just updating post - when "undecoded and Meiantech/Atlantic/Aidebao" mode is set - the message is:

Code: Select all

------------------------------------------------
------------------------------------------------
Packettype        = UNDECODED RF Message
UNDECODED VISONIC:236303548860 
------------------------------------------------

subtype       = Meiantech/Atlantic/Aidebao

status        = Motion
battery level = OK
