hm ok, strange. I also run out of ideas, sry.
My last idea: search your core.entity_registry file for duplicated entities. So the same as before but with _2 as ending. New entities get added at the end of the file/list.
You know what, after a restart I noticed the right button switch is no longer in the core.entity_registry. I made some changes and decided to reboot again before I try to remove the switch and add it back. But after the reboot the right button switch came backā¦ so weird but itās fixed now 
Thank you so much @h4nc!

sorryā¦ didnĀ“t read the config well. removed post.
I have changed the Anonimous value from āfalseā to ātrueā in the mosquitto configuration and now the sensors appear as entities, but they appear as unavailable and I cannot use them and the coordinator value appears as āunknownā.
Does somebody knows why it could be?
It seems HA canāt access the mqtt broker. If you use the mosquitto add-on, the Anonimous value needs to be āfalseā and you need to create a user for the mqtt broker.
I have changed anonymous: false
I have created a new user in HA => āmqtteducasaā and now the following appears in the mqtt broker log

I still see the devices and their operation in the zigbee2mqtt addon log, but the entities in HA do not appear either 
Zigbee2MQTT use for server:
server: 'mqtt://core-mosquitto'
I had very strange non-random issues when I used something else. It is working flawlessly for a couple of months now.
ā¦
Furthermore,
zigbee2mqtt has for server:
"server": "mqtt://ipraspberry",
and zigbee2mqtt connection log states:
zigbee2mqtt:info 2020-01-28 22:36:28: Connecting to MQTT server at mqtt://iddelaraspberry
Is there not a typo somewhere?
ā¦
Do install the Zigbee2mqttAssistant add-on. A Web GUI for the Zigbee2Mqtt software. It helped me enormously.
See https://github.com/yllibed/Zigbee2MqttAssistant#installation
ā¦
Do you have the Mosquitto broker integration?
Did you check/enable this setting within the mosquitto broker?
HA -> Configuration -> Integrations -> Mosquitto broker -> Navigate to upper right hand corner and click on 
Hi rlems! Thanks for your answer.
On the zigbee2mqtt server I tried with:
āmqtt://homeassistantā
āmqtt://192.16ā¦ā
āmqtt://core-mosquittoā
With all of them the addon apparently connects to mqtt broker, but then in no case do the devices appear as an entity in HA.
The typo is mine by hiding the raspberryās ip in the post, sorry.
Yes, I have the zigbee2mqttAssistant addon installed and there is the coordinator and the two devices that I have activated right now, and the connection between them. But I donāt get it to work.
The mosquitto broker integration is correct.
Thanks
Are you using MQTT autodiscover? I long ago decided to take the manual route and Iām very happy with it, though it requieres expanding the configuration.yaml file a lot. How do you plan to get HA to deal with the Mqtt devices?
Yes, I am using mosquitto autodiscover, and also, I have manually zigbee devices in the configuration.yaml file. I donāt know if both are compatible ā¦
binary_sensor:
- platform: "mqtt"
name: sensor_movimiento_garaje
state_topic: "zigbee2mqtt/0x00158d00032bd33c"
availability_topic: "zigbee2mqtt/bridge/state"
payload_on: true
payload_off: false
value_template: "{{ value_json.occupancy }}"
device_class: "motion"
- platform: "mqtt"
name: sensor_entrada_principal
state_topic: "zigbee2mqtt/0x00158d0003f1cde6"
availability_topic: "zigbee2mqtt/bridge/state"
payload_on: false
payload_off: true
value_template: "{{ value_json.contact }}"
device_class: "door"
But neither do the devices appear in the entities tab
I think the problem may come, as Francis pointed out before, in the connection between HA and mosquitto, but I dont know what I should change.
EDIT:
Well, I removed the mqtt integration, and also commented on the mqtt code in the configuration.yaml file. Now you have re-created the mqtt integration from the integrations panel and the entities are already appearing, but:
1.- The entities appear because they have been added manually in the configuration.yaml file, if I comment that part of the code, HA still does not detect the zigbee devices.
2.- Zigbee2mqtt reads the devices and their changes, that are added in the devices.yaml file, not the devices added manually in the configuration.yaml file.
3.- Mqtt.fx also reads the devices and their changes, added in the devices.yaml file, does not read the devices added manually in the configuration.yaml file.
EDIT2:
Today, finally, after more than three months, zigbee devices work on my HA. 
I eliminated the mosquitto integration, once again, and this time, HomeAssistant detected that there were mosquitto devices pending to integrate, I made the automatic integration and now if the zigbee devices that I had paired appear as entities.
@aidbish @nickrout @wixoff can anyone confirm the flashing or pairing process? I canāt seem to get it to be interviewed.
/edit Nevermindā¦ found below the 2530_2591 firmware post and it worked like a charmā¦ thanks!
Can you please share examples of database.db and devices.yaml created by hass.io add-on?
Iām trying to migrate a Zigbee2MQTT installation in an hassbian system to the hass.io add-on and noticed that file contentsā structure doesnāt seem to be 100% the same in all cases (enough to check configuration.yaml differences).
Has anyone did this before?
Thanks in advance.
Hi.
Sorry, bur from āconfiguratorā web interface I cannot access the zigbee2mqtt folder.
I can do it tonight at home.

Zigbee2MQTT configuration.yaml is YAML and add-on is JSON, just not sure if this is only applicable to configuration and not other files? (devices.yaml, database.db, etc).
Can anyone provide real life examples of all Zigbee2MQTT files when using the add-on?
Thanks in advance.

Hey all, I replaced CC2531 with a CC2531 which came with the antenna pre installed from ebay and made my original CC2531 a repeater. Since then my zigbee network has become pretty unreliable and generally slow. Before I switch back to the original CC2531 is there anything I should try?
Thanks
Thanks a lot.
This allowed me a smooth transition from an hassbian based installation to hass.io
Btw, does anyone know how the Zigbee2mqtt updates appear on hass.io, or there is an add-on update every time a new Zigbee2mqtt version is released?
I just noticed that 1.11.0 got released, but nothing seem to appear in hass.io (add-on currently running 1.10.0).
Thanks in advance.
Itās an add-on update, but since the add-on and zigbee2mqtt are maintained by different people there is a slight delay. A pull request for the update to 1.11.0 already exists, but still needs to be merged. Then the docker container for the add-on needs to be built.

The routes to the new coordinator in your mesh need to re-discovered and that might take up to a day, so it should get more stable with time. You can also try using Zigbee2MqttAssistant to visualize your mesh and see if there is anything funky going on.
If I decide to ditch the Hue Bridge and move everything over the Z2M, would I be able to use the official Hue app somehow? thanks
