Fibaro single switch on daikin Inverter air condition

[Jibran 2]

Hello,

 

I have 3 daikin inverter split ac. i want to connect fibaro single switch on them . Please someone tell me can it be possible with these specs ? I have the specification sheet which is shown below

 

Thankyou .

What do you want to achieve, measure electric usage or switch On/Off  all three devices at same time?

[Jibran 2]

 I want them to switch on and off and want to measure electric usage.  basically i am using global cache devices to switch them on and off .  But i also want to measure the power so is this feasible solution ?

[petergebruers 1,265]

No. It is an inductive load, so it does not meet these requirements (copied from Switch 2 manual, emphasis is mine):

 

"When connecting the Switch 2 act in accordance with the following

rules::

Do not connect loads greater than those recommended!!

Do not connect types of loads other than resistive and

incandescent!!"

[Jibran 2]

That means i cannot connect module to the AC. Ok. But what about 600W dc Power supply? can single switch 2 bear that ?

[petergebruers 1,265]

That is not recommend either. Your contacts will weld (stick). Use a big, secondary relay between the Z-Wave module and the load (supply, air conditioner, pump, ...). Sorry, no power measurement...

 

Aeon makes a "heavy duty" relay but I doubt it meets your requirements, I have to look it up. Nominal current is not the only issue, it is peak current and arcing due to inductive kickback that kills small relays...

[Jibran 2]

what about fibaro Wall Plug ?

[petergebruers 1,265]

Maybe it can control the dc supply. Can you post a link to the datasheet of your supply?

[Jibran 2]

Actually nothing is written on the power supply. just input voltage that is 220v and input current (MAX) 4 amps .Power is 200w. but there are 3 power supply so combine power will be approximately 600w.

[petergebruers 1,265]

I would not do that. You might want to read parts of this very old topic I wrote because my relay got "stuck":

 

 

[Jibran 2]

O yes i have read that. But that is double relay . i have double relay , it also stucks so that is why only use resistive load on them. But i am also using single switch 2 on 10 to 14 leds of 7w each. i think it has been 7 months , working fine. So you suggest that i should not use any of these modules on 600w load ?

IMHO simple solution for you is:

buy:

Remotec Z-Wave ZXT-120 IR Extender for Air Conditioners (~$80)

or

Arduino Z-UNO $65 + IR Transmitter ~$2, Receiver ~$3 (Bonus: You may add more than 20 z-wave devices out of box)

I see it this way. The single switch is better than the double. True. And the newer "switch 2" is better than the old one. But they say "resistive load only". And the Fibaro Wall Plug is better again, it has a good relay... But remember, a 20 W supply could weld the oldest relay. And you want to turn on 600 W... Also, the wall plug has overload and overcurrent protection, so it might not even turn on such a load... If you want to give it a try, use the newest Fib plug and only one supply to begin with...

[Jibran 2]

Ok i will definitely try it. Thankyou

Hehehe, that is a fun idea, you probably know I toy with Z-Uno too. One possible issue: I've read that the IR buffer is quite limited, and someone posted on the Z-Uno forum that his IR code does not fit. To be tested!

I am using Global cache device instead of Remotec. it is more stable and easy to catch the code from remote. Remotec is a good device but it is only with the air conditions which only have cooling function in it. I have version 1.2.

yes. I had tried to make air-conditioner controller based on Z-UNO, but yes unluck. simple sketch properly worked on Arduino UNO and glitch on Z-UNO.

notice: all my test was for Z-UNO version from Jan 2017. Currently, my Z-Uno used for others things...

Aren't all Daikin products expandable with Wi-Fi module?

This will ease the integration i.m.h.o.

can you point me to the "Global cache device description"?

 

thnak you!

[Jibran 2]

its a global cache itach wifi to ir Module with 3 pin connection.
