Controller Information*

• Manufacturer: Sonoff
• Model: SNZB-04
• Short Description: Sonoff contact sensor (e.g. open window)
• Image: https://sonoff.tech/wp-content/uploads/2021/01/SNZB-03.jpg

Actions

If possible, provide here mappings for actions which can be triggered with this controller. Specify the integration these mappings refer to. If you want to provide mappings for multiple integrations, you can duplicate the following section as needed.

[Integration] (e.g. deCONZ, ZHA, Zigbee2MQTT)

Zigbee2MQTT: https://www.zigbee2mqtt.io/devices/SNZB-04.html deCONZ: https://github.com/dresden-elektronik/deconz-rest-plugin/issues/3036 https://zigbee.blakadder.com/Sonoff_SNZB-04.html

• contact: binary sensor (closed = both elements nearby, open = elements are far from each other)

Additional Details*

• [X] I'd like to help developing this blueprint
• [ ] I've found a blueprint/automation not included in this project which integrates this controller
  • Link to the resources you've found: Resource name here

Additional context

Looks like refresh rate of this device is pretty low.

Hi @KrzysztofHajdamowicz, thank you for the suggestion.

This project currently implements support for controllers such as switches, remotes etc. Since contact sensors are not part of this category, they are currently not being considered, but you raised an interesting idea: we can not only limit support to actual controllers, but implement functionality for any kind of device which is associated with some sort of "action".

For now I won't proceed on implementing a blueprint for this device, but this is something which we could definitely consider in the future, since we need to understand how to categorize such devices in our collection, which probably requires a little bit of thinking.

I'll leave this issue open for future reference. Thanks again! :)

No problem! I'm using this sensor in a room, that is basically "enter into, pick your thing, get out and close the door", this makes my automation working exactly as fridge doors- light is on as long as doors are open.

Hi, any plans to support this device?

[KrzysztofHajdamowicz]

Dunno, it depends on @EPMatt. For me, contact sensor works as a light switch.
