zhimi.heater.nb1 indicator_light wrong behaviour

[FrancYescO]

zhimi.heater.nb1

Controlling this entity causes wrong behaviours: Turning the switch on or off will instead turn the heater on or off and not just the LED lights indicator changing brightness is likely inverted: from 1 to 49 = LED in HIGH brightness mode = attribute Indicator light.brightness 0 from 50 to 99 = LED in LOW brightness mode = attribute Indicator light.brightness 1 100 = LED off (like screenshot above) = attribute Indicator light.brightness 2

thanks, i've notice also another little thing: a default entity switch is created with nothing specific on the entity id neither on name (will get the name of the device), i've noticed that this entity will control the "Return to middle" function (for the default on-off there is an entity called switch.zhimi_nb1_897a_switch_status)

and finally i have this issue, that idk if depends on your integration specifilcally: when trying to turn on-off via alexa (using the climate.* entity), it work but when turning off i get this exception (and alexa voice respond with an error message while is not):

i think also a default generated entity that keeps track of the Warm/Hot mode is usefull, actually the only way to change this mode is using this dropdown from the climate entity page:

has unsupported state value 'fan not swing'

This component can't do anything about it.

Just tried last release 0.5.4 the behaviour of light is still a little confusing:

• brightness still inverted (HIGH 1-49,LOW 50-99, OFF 100)
• trying to put the switch off, will turn for 1sec the led to low brightness mode, than the switch came back in the on position and the lights on the heater goes off

[FrancYescO]

has unsupported state value 'fan not swing'

This component can't do anything about it.

Is possible to report, instead of 'fan not swing' and 'fan swing' status (preset) the operation or fan mode, that is more indicative of the status of the heater?

Hi, the zhimi.airpurifier.za1 has the same indicator light behaviour. So the light switch turns on/off the device instead of the light and brightness isn't working correctly.

@schneivo77 Try master branch.

Hi @al-one,

thanks for the fix! Unfortunately it doesn't work correctly at the moment.

Light status is always 'on'. When the light on the airpurifier is on and I click the switch in the hassio UI, it turns off on the device but in the UI it still shows 'on' and I'm not able to turn it back on via the UI.

Try master branch again.

Seems to work correctly now! Thank you! 👍
