Mi-Light controller for Mysensors

[ted]

Assuming the on-air protocols are the same, yes.
I only have the RGB-W light bulb and were able to control it without ever using the remote controller.

@ted said:

(1) turn the white light on/off using a light switch node

What does this mean? do I connect a light switch to the repeater-node? Or does it just mean that I can use another arduino to detect button-switches and send command to domoticz or other controller?

[Cliff Karlsson]

I have received my lamps now but no controller yet. Is it possible to pair/control the bulbs without controller?

[ted]

@Cliff-Karlsson
To pair, turn on the light switch, and send 'ON' command within 2-3 seconds. If successful, you will see the light flash on and off a couple of times.

The repeater-node simply relay any command it receives from the controller (I use openhab) to the light wirelessly. There is no physical wire connection between the node and milight.

[Cliff Karlsson]

Ok, I meant to say that I had not got any bridge for the mi-light yet. In the first post it is mentioned that you need to pair using a bridge.

@Cliff-Karlsson
thanks, the original post was updated to clarify this.

[Cliff Karlsson]

Thanks, next stupid question. How do I control the rgb/dimming features of the lamp? I got a ordinary on/off lamp under device in domoticz.

[ted]

@Cliff-Karlsson
You have to program your controller to produce the command string and send it to the node. The command string is transmitted as a ASCII string to the 'custom' node. See https://hackaday.io/project/5888-reverse-engineering-the-milight-on-air-protocol for the command format. Sorry I don't use domoticz.

Do I need to unpair the bulbs if I want to try pairing again? It got paired as a regular on/of bulb the first time. But I think I found out that I could add mi-lights using a dummy switch. But The bulb are not pairing.

@Cliff-Karlsson
I don't know. Let us know what you find out. :)
To unpair, you turn on the power to the bulb and send 'off' command within seconds.

[Cliff Karlsson]

Ok, I tried with several bulbs now. First time I managed to pair as on/off switch but after that I had no luck. If anyone is using this with domoticz please describe the procedure of how to add the bulbs.

[Cliff Karlsson]

@ted

I forgot to ask, but what controller have you been trying them out on? And are there any limitation to how many bulbs one repeater-node can control? I recall reading something about one original controller only being able to control 4 bulbs or similar.

[Cliff Karlsson]

Ok, I think I found a clue :), S_CUSTOM seams not to be supported by domoticz so I changed it to "gw.present(0, S_RGBW_LIGHT);"
So now everything looks ok with a RGB selector and everything. But I still can only turn on and off the bulb and am not able to dim or set colors. So I guess there is some more serious witchcraft going on thats over my head.

@Cliff-Karlsson

The milight uses a speical command, it is not likely to be compatible with the standard RGB light module in domoticz. The information about the milight protocol can be found here: https://hackaday.io/project/5888-reverse-engineering-the-milight-on-air-protocol

I used openhab to assemble the command string for S_CUSTOM. Using the S_CUSTOM, you can control as many bulb as you want (by using different remote ID field in the milight protocol), although I only have 1 bulb. The node receives the milight protocol in plain ASCII string and convert the string to HEX before sending it out to the bulb. Hope this helps.

[Cliff Karlsson]

Ok, thanks for the help but it seams that I will have to use the standard-wifi bridges for now until someone smarter than me fixes the domoticz support.

Thank You for this solutin. Everythin works great but...

I was able to pair with one bulb but I I do not know what to do to pair with others?

Any idea?

Best regard

@Łukasz-Kostrzewa
Each bulb is associated with a particular 'remote ID'. Bulbs having the same remote ID will repond to all commands having the same remote ID. Therefore, you can simply pick a different(or the same) remote ID to pair with a second bulb, and the second bulb can be controlled separately(or simultaneously) with the first one. I have not tried it but that should work according to the mi-bulb protocol.

Thax for reply

But I don't understand :(
I don't have Milight bridge and I paired one Milight bulb to Dummy switch I have in my Domoticz My sensors.
And this works great but there is only one dummy switch.
When I add to arduino code one more (gw.present(0, S_LIGHT);) in Domoticz there is another Dummy switch but it controls the same lights then the first one. I don't know how to add (I don;t know it is possible) a second dummy to control another bulb without milight bridge.

[Łukasz Kostrzewa]

Hi Ted

I understand now:)
I changed remote id to diffrent values but now my first dummy switch paired to my first bulb doesn't work.
I need to have another arduino to control another bulb?
Best regards

Another question...
Is there possibility to add to this code another one to control DHT11 temp and humidity sensor (from my sensors library)
I wanted to have 2 thing in one:)
Best regards
