Edge Driver (Beta) How to write a value in an attribute of a zigbee cluster?

Hello

Has anyone found in the edge lua libraries how to write a value in an attribute of a zigbee cluster?

For example:

I want to write a 1 (true) or 0 (false) in attribute 0x0055 of cluster 0x0010, data type Boolean.
In grovvy it was done like this:

zigbee.writeAttribute (0x0010, 0x0055, DataType.BOOLEAN, 0)

zigbee.writeAttribute (0x0010, 0x0055, DataType.BOOLEAN, 1)

I am quite clumsy, I have tried several things and I have not succeeded

This could also be used for devices such as a switch, to be able to configure what to do in case of power restoration, go off, on, keep last state, for example.

Thanks

If the default handlers and libraries haven’t worked for you. Here’s an implementation sample I used to build the TX message directly to write an attribute value:

--imports
local zcl_messages = require "st.zigbee.zcl"
local messages = require "st.zigbee.messages"
local data_types = require "st.zigbee.data_types"
local write_attribute = require "st.zigbee.zcl.global_commands.write_attribute"
local zb_const = require "st.zigbee.constants"

-- Build the complete ZCL message and send it to the device
local build_zcl_message = function(device,cluster_id,zclh,body_message,mfg_specific_code)
    local addrh = messages.AddressHeader(
            zb_const.HUB.ADDR,
            zb_const.HUB.ENDPOINT,
            device:get_short_address(),
            device:get_endpoint(cluster_id),
            zb_const.HA_PROFILE_ID,
            cluster_id
    )
    local message_body = zcl_messages.ZclMessageBody({
        zcl_header = zclh,
        zcl_body = body_message
    })
    local txMessage = messages.ZigbeeMessageTx({
        address_header = addrh,
        body = message_body
    })
    --Add the manufacturer info if exists
    if mfg_specific_code then
        txMessage.body.zcl_header.frame_ctrl:set_mfg_specific()
        txMessage.body.zcl_header.mfg_code = data_types.validate_or_build_type(mfg_specific_code, data_types.Uint16, "mfg_code")
    end
    device:send(txMessage)
end

--Function to write a cluster attribute
local build_write_tx_message = function(device, cluster_id, attr_id, mfg_specific_code,attr_type, attr_value)
    local zclh = zcl_messages.ZclHeader({
        cmd = data_types.ZCLCommandId(write_attribute.WriteAttribute.ID)
    })
    local attr_write = write_attribute.WriteAttributeAttributeRecord(
            data_types.AttributeId(attr_id),
            data_types.ZigbeeDataType(data_types[attr_type].ID),
            data_types[attr_type](attr_value)
    )
    local write_body = write_attribute.WriteAttribute({ attr_write })
    build_zcl_message(device,cluster_id,zclh,write_body,mfg_specific_code)
end

--usage sample, this is using the values you shared before
buildWriteTxMessage(device, 0x0010, 0x0055, [manufacturerCode-optional], "Boolean", 0x0001)

The parameter mfg_specific_code can be included when the cluster is manufacturer-specific, if not, it can be omitted.

Please let me know your results

Thank you. @nayelyz

I had already achieved it a while ago
There is nothing better than speaking out loud (Alexa) and inspiration comes to you.

Awesome! Is it possible you share the solution so others can take reference from it, please?
Thanks!
