How to set state of switch/dimmer through REST API?
From python bash I send request:

data123 = {'DimmedZal4': str(intens)}

requests.put('http://192.168.1.3:8080/basicui/CMD', data123)

In .rule:

rule "RULE_Dimmer_DimmedZal41"

when

	Item DimmedZal4 received update

then

	logInfo("Exec4", 'DimmedZal4 received update: ' + DimmedZal4.state.toString)

end

rule "RULE_Dimmer_DimmedZal42"

when

	Item DimmedZal4 received command

then

	logInfo("Exec4", 'DimmedZal4 received command: ' + DimmedZal4.state.toString)

end

rule "RULE_Dimmer_DimmedZal43"

when

	Item DimmedZal4 changed

then

	logInfo("Exec4", 'DimmedZal4 changed: ' + DimmedZal4.state.toString)

end

In OH2 log:

2017-02-27 16:13:32.108 [INFO ] [eclipse.smarthome.model.script.Exec4] - DimmedZal4 received command: 100
2017-02-27 16:13:32.115 [INFO ] [eclipse.smarthome.model.script.Exec4] - DimmedZal4 received update: 100
2017-02-27 16:13:32.154 [INFO ] [eclipse.smarthome.model.script.Exec4] - DimmedZal4 changed: 100

How just to update state of switch/dimmer without event “received command”?

If my lamp is ON, then python must send notification to OH about change state of Item.
But if I change state of Item from OH, then OH.rule must send command to lamp.

SOLVED!
In python bash (OpenHabian OpenHab2):

requests.put('http://192.168.1.3:8080/rest/items/DimmedZal4/state', str(intens))

In rules rule-trigger does not triggered:

rule "RULE_Dimmer_DimmedZal42"

when

	Item DimmedZal4 received command

And this right!
