Entities with Friendly Names not showing in Groups - SOLVED

Hi there, first post and starting on HA.
I’ve came across an awkward issue regarding usage of Friendly Names in tabbed groups.
I have several outlets and wall switches (for ceiling lights) controlled by a Broadlink RM Pro, I’ve configured them all in HA and then created 2 groups separating “Outlets” and “Ceiling Lights”, The groups work fine (aside from the friendly name of the group not showing, only “Switches”) and I can see the entities where I defined “Friendly Names” in the “Home” and “Outlets” group, however, if I define any “Friendly Name” in entities of the “Ceiling Lights” those entities simply vanish. Note that the same entities appear with their friendly names in the home screen.
Focus on the 2 entities “living_room_left_lights” (friendly name: “Living Room Left”) and “living_room_right_lights” (friendly name: “Living Room Right”) in the screenshots and configuration.yaml bellow to illustrate this issue.
Of course it goes without saying but thanks in advance, I’ve learned a lot from this awesome community.

Please edit the post to format correctly or use hastebin to paste all the code. Very hard to see what is wrong there.

P.s. I edited your post.

You have commented out friendly_names for most of your switches. # before a line is ignored by HA

^ what he said regarding the friendly names. Regarding the name on the card…

A common newbie error. You’re not the first, and you won’t be the last.

You’ve created two views (tabs). You have not created two cards.

Remove the line view: yes to make them in to cards.

If you then want them on separate views, you need to create a new view, and list the card group in its entities.

Hi arsaboo, first of all thanks for your swift reply. and second thanks for helping with the format.
The comments on most friendly_names are intentional because that is the only way I can make the switches appear in the “Ceiling Lights” tab and that’s the problem, if I remove the “#” they will not appear there, only in the “Home” screen. See below, notice that entities with friendly names don’t show up.

mf_social, thanks as well for the recommendation, as I said the comments are intentional, I’m aware of the purpose of “#” for comments.
About the names on the card, I want to create tabs, not card. I create tabs by setting “view: yes” but my point is that naming title within those show as “Switch”

The commented friendly_name should have no effect on whether they appear in a group. It only affects how it appears in a group.

Also, the screenshot does not perfectly map to the config you shared.

arsaboo, indeed it shouldn’t have effect but it does. If you count the number of entities in the yaml file for that group, they are 12 but in the screenshot only 10 appear. Guess which are the ones not showing… the 2 that have friendly_names.
That IS the problem.

Yes, but you have to create a card to show on the view.

At this time you have a named view, that view contains ungrouped switches, so the system groups them on to a card called switch.

If you want to name the card, you must create the card, then display the card on the view.

Exactly, as @anon43302295 said, the problem is with your group definition and not friendly_names.

OK, I’m getting somewhere but still feel a strange behaviour after the changes you recommended
Cards show up although the two of the entities with friendly names appear on an “orphan” card. I don’t understand the difference between the “Outlets” card and “Ceiling Lights” card.
And by the way, I like this view but I would still prefer a tab approach. I’m sure I’m missing a key aspect in formatting so again thanks for your patience.

I can’t explain it any clearer, sorry.

Carefully read back through my replies in this thread, and if you still don’t get it somebody else is going to need to chime in with a better explanation. :+1:

Hi again, thanks to this post I’ve been able to have both cards and views and the title on each one looks exactly as expected.
The issue with orphan entities remains though. Although I have both “living_room_left_lights” and “living_room_right_lights” under group “Ceiling Lights” they show up in card “Switch” only, the only difference between those and the remaining entities that do show up correctly in “Ceiling Lights” card is the fact they have friendly_name declared.

  living_room_right_lights:
    friendly_name: "Living Room Right"

  hall_lights:
    #friendly_name: "Hall"

ceiling_lights:
    name: "Ceiling Lights"
    #view: yes
    #icon: mdi:lightbulb
    entities:
      - switch.living_room_left_lights
      - switch.living_room_right_lights
      - switch.hall_lights
      - switch.exterior_lights

Then the entity_id’s are incorrect, probably switch.living_room_left and ...right (no ‘light’) based on the output you have in the screenshot.

The relevant part of the code is in my previous post, you can compare them and I’ve checked that countless times, also when I select the whole ID in the declaration is “marks” exactly the same in the groups so I’mm 100% sure there’s no ID mismatch. The fact that friendly_name doesn’t have the word “lights” on it shouldn’t matter, right?

OK I found a workaround by using config/customize.yaml
