[SOLVED] H801 Tasmota - send MQTT command to change color

Setup, Configuration and Use Scripts & Rules
1

Hi there,

I would like to do the same as described in this thread.

Unfortunately, I’m facing problems with adopting this to the new mqtt 2.4 binding.

So, the aim is to send a mqtt command from openhab to the H801 controller.

// .items
Number test_mqtt_led

// .sitemap
    Frame label="MQTT send" {
        Switch item=test_mqtt_led mappings=[3="grün", 2="rot", 1="blau", 0="Aus"]
    }

// .rules
rule "MQTT send"
when 
    Item test_mqtt_led changed                       
then
    switch (test_mqtt_led.state as DecimalType) {
        case 0 : {
            // send power = off via mqtt
            logInfo("RULE", "--> LED: AUS")
        }
        case 1 : {
            // send color = 1 via mqtt
            logInfo("RULE", "--> LED: 1")
        }
        case 2 : {
            // send color = 2 via mqtt
            logInfo("RULE", "--> LED: 2")
        }
        case 3 : {
            // send color = 3 via mqtt
            logInfo("RULE", "--> LED: 3")
        }
    }
end

Instead of the comment lines // send ... the mqtt command should be there.
For example if case = 1 color should be set to 1.

In tasmota console of H801 it is possible with color 1
The output is:

tasmota/sonoff-2550-h801/stat/RESULT = {"POWER":"ON","Dimmer":100,"Color":"FF00000000","HSBColor":"0,100,100","Channel":[100,0,0,0,0],"CT":327}

My mqtt broker is defined as Bridge mqtt:broker:mosquitto in .things file.
The H801 thing is

	Thing topic h801_2550 "LED H801 #1 (sonoff-2550-h801)" @ "MQTT" {
      Channels:
        Type switch : h801_2550_switch			"LED H801 #1: Power Switch"             	[ stateTopic="tasmota/sonoff-2550-h801/stat/POWER", commandTopic="tasmota/sonoff-2550-h801/cmnd/POWER", on="ON", off="OFF" ]
        Type colorHSB : h801_2550_color 		"LED H801 #1: Farbe"              			[ stateTopic="tasmota/sonoff-2550-h801/stat/RESULT/HSBColor", commandTopic="tasmota/sonoff-2550-h801/cmnd/HSBColor" ]
		Type string : h801_2550_reachable  		"LED H801 #1: Reachable"          			[ stateTopic="tasmota/sonoff-2550-h801/tele/LWT" ]
		Type number : h801_2550_rssi       		"LED H801 #1: Empfang: RSSI" 				[ stateTopic="tasmota/sonoff-2550-h801/stat/STATE", transformationPattern="JSONPATH:$.Wifi.RSSI"]
    }
2

Ok so the tasmota command is color and the payload is 1
The topic would then be: tasmota/sonoff-2550-h801/cmnd and the payload 1
So do this:

		Type number : h801_2550_tasmocolor       		"LED H801 #1: Empfang: Color" 				[ commandTopic="tasmota/sonoff-2550-h801/cmnd/color", formatBeforePublish="%d"]

Create a number item linked to that channel
Link a switch item to the switch channel
Then your rule is:

rule "MQTT send"
when 
    Item test_mqtt_led changed                       
then
    switch (test_mqtt_led.state as DecimalType) {
        case 0 : {
            // send power = off via mqtt
            mySwitchItem.sendCommand(OFF)
            logInfo("RULE", "--> LED: AUS")
        }
        case 1 : {
            // send color = 1 via mqtt
            myTasmoColorItem.sendCommand(1)
            logInfo("RULE", "--> LED: 1")
        }
        case 2 : {
            // send color = 2 via mqtt
            myTasmoColorItem.sendCommand(2)
            logInfo("RULE", "--> LED: 2")
        }
        case 3 : {
            // send color = 3 via mqtt
            myTasmoColorItem.sendCommand(3)
            logInfo("RULE", "--> LED: 3")
        }
    }
end

Many thanks! It works like a charm.

Now I’m trying to get the command scheme work.
I suppose it’s quite the same - but nothing happens.

Tasmota console:

CMD: scheme 2
MQT: tasmota/sonoff-2550-h801/stat/RESULT = {"Scheme":2}

My MQTT Channel:

Type number : h801_2550_scheme      	"LED H801 #1: Scheme" 						[ commandTopic="tasmota/sonoff-2550-h801/cmnd/Scheme", formatBeforePublish="%d"]

Log:

[ome.event.ItemCommandEvent] - Item 'OG_bad_l_led1_schemev' received command 2
[vent.ItemStateChangedEvent] - OG_bad_l_led1_schemev changed from 0 to 2

Your rule and your item please

														 4="random cycle through colors using Speed and Fade"]

Commands according to Tasmota wiki

Scheme	Light effects
+ = next scheme
- = previous scheme
0 = single color for LED light (default)
1 = start wake up sequence (same as Wakeup)
2 = cycle up through colors using Speed option
3 = cycle down through colors using Speed option
4 = random cycle through colors using Speed and Fade

Don’t see much wrong
Try that:
commandTopic="tasmota/sonoff-2550-h801/cmnd/scheme"

7

… without formatBeforePublish="%d" ?

Still nothing happens :frowning:

Type number : h801_2550_scheme      	"LED H801 #1: Scheme" 						[ commandTopic="tasmota/sonoff-2550-h801/cmnd/scheme" ]

[ome.event.ItemCommandEvent] - Item 'OG_bad_l_led1_schemev' received command 2

No with formatBeforePublish="%d"

scheme instead of Scheme

And monitor the MQTT messages
Check the Tasmota console too

9

When sending scheme 1 via Tasmota console the output is as follows:

Console

CMD: scheme 1
MQT: tasmota/sonoff-2550-h801/stat/RESULT = {"Scheme":1}

MQTT.fx

{"Scheme":1}

But firing via OH sitemap there are no entries in MQTT.fx and console

10

Then there is somthing wrong with either your channel or item definition

As said before, your RGB color code (#2) works fine …

12

Here is your problem:
Channel:

		Type number : h801_2550_scheme      	"LED H801 #1: Scheme" 						[ commandTopic="tasmota/sonoff-2550-h801/cmnd/scheme", formatBeforePublish="%d" ]

Item:

Number      OG_bad_l_led1_scheme            "Bad OG: LED - Scheme"             <light>          (gM,gR,Glicht)      {channel="mqtt:topic:mosquitto:h801_2550:h801_2550_Scheme"}

Notice the difference (Think capital letters again)

13

Uh, your’re right.

Many thanks! And sorry for bothering you …

14

But it’s still confusing, as the MQTT output is with capital letters … (as I did in #5)

"POWER":"ON","Dimmer":100,"Color":"FF00000000","HSBColor":"0,100,100","Channel":[100,0,0,0,0],"CT":153,"Scheme":0,"Fade":"ON","Speed":1,"LedTable":"OFF"
15

I think Tasmota doesn’t care
