+      { visibility = { displayed = false } }))

+    device:send(cluster_base.write_manufacturer_specific_attribute(device,
+      PRIVATE_CLUSTER_ID, PRIVATE_ATTRIBUTE_ID, MFG_CODE, data_types.Uint8, 0x01)) -- private


I dont really know what this attribute write does, but is it something that should be done in device init? The difference being it would be written anytime the hub restarts or the driver is updated

Looks like this was moved to infoChanged to handle preference changes. It seems like it might still be needed in the added handler so that the initial preference default value is written.

When the device is entering the pairing process, it will restore the data to the default values, and both ends will have the same default values.

Can code coverage be improved in firstled-io/init.lua? Device init tests, preference changes, scenes cluster handling, profile switching, that kind of thing

The maximum improvement can only reach 88%. What suggestions do you have?

The maximum improvement can only reach 88%. What suggestions do you have?

You can run coverage locally and get the report yourself. When I do it I see that none of the child button behavior is tested.

To run it locally first run your test file with coveraged enabled (note you need luacov installed)

## run test with coverage enabled from zigbee-switch/src
lua -lluacov test/test_firstled_switch.lua
## create the report from the stats output
luacov -c ./luacov.stats.out --config ~/SmartThingsEdgeDrivers/tools/config.luacov

This will create a luacov.report.out with counts next to each line in each file that was required during the lua script. Here is what I was seeing relating to the firstled-io/init.lua file:

       local function get_child_profile_name(device)
*****0   for _, fingerprint in ipairs(FINGERPRINTS) do
*****0     if device:get_model() == fingerprint.model then
*****0       return fingerprint.child_profile
           end
         end
       end

       local function find_child(parent, ep_id)
    23   return parent:get_child_by_parent_assigned_key(string.format("%02X", ep_id))
       end

       local function device_added(driver, device)
         -- Only create children for the actual Zigbee device and not the children
     8   if device.network_type == device_lib.NETWORK_TYPE_ZIGBEE then
     1     local children_amount = get_children_amount(device)
     1     if children_amount >= 2 then
     4       for i = 2, children_amount, 1 do
     3         if find_child(device, i) == nil then
*****0           local name = string.format("%s%d", string.sub(device.label, 0, -2), i)
*****0           local child_profile = get_child_profile_name(device)
*****0           local metadata = {
                   type = "EDGE_CHILD",
                   label = name,
                   profile = child_profile,
                   parent_device_id = device.id,
                   parent_assigned_child_key = string.format("%02X", i),
*****0             vendor_provided_label = name
                 }
*****0           driver:try_create_device(metadata)
               end
             end
           end

         -- Create Button if necessary
     1     local button_amount = get_button_amount(device)
     1     if button_amount >= 1 then
     5       for i = children_amount + 1, children_amount + button_amount, 1 do
     4         if find_child(device, i) == nil then
*****0           local name = string.format("%s%d", string.sub(device.label, 0, -2), i)
*****0           local metadata = {
                   type = "EDGE_CHILD",
                   label = name,
                   profile = "button",
                   parent_device_id = device.id,
                   parent_assigned_child_key = string.format("%02X", i),
                   vendor_provided_label = name,
                 }
*****0           driver:try_create_device(metadata)
               end
             end

Hi @thinkaName , it looks like this PR branch is out of date with main. Please update it with the latest main and push the result. Then we can re-review.

cjswedes

It seems like there was a lot of stuff added since the last reviews wrt child devices, but we cant tell because you are obfuscating the commit history by always force pushing; this makes it hard to review this PR and others you have submitted. Please keep incremental changes in their own commits until we have approved the PR.

+return {
+  { mfr = "FIRSTLED", model = "M4S4BAC",  buttons = 4 ,  children = 4, child_profile = "switch-button-wireless" }


How are the number of buttons and children used? Please describe the way the device is intended to be integrated, since it is not clear from the code in its current state. My assumption is that there is a single zigbee device with 4 buttons, and you are trying to have a child device for each button.

What is the goal of using child devices to represent individual buttons? The approach we take on the platform is to use a multi component profile that has a component for each button.

Since this is the first product submitted, a series of devices will be added to reuse this driver. Currently, this is the 4+4 model, consisting of 4 switches that can be set to button mode, plus 4 pure buttons. The number of child devices to be created is determined by "fingerprints.children", and the number of buttons to be created is determined by "fingerprints.buttons". Subsequently, models such as 3+3, 2+2, and 1+1 will be added. Additionally, there will be models without the button, and the setting for fingerprints will be fingerprints.buttons=0.

Thank you, this clears up a lot of my confusion with what is going on with the child devices. You may want to add a comment at the top of this subdriver explaining how this device works.

Because it was previously informed that a device's PR could only have one commit, so the forced override push was carried out.

I apologize for the confusion. We do want there to only be a single commit when we merge, but it is useful to see how feedback is addressed by keeping commits separate during the review period.
