Test to see if your Synology NAS is using 4k sectors

Login using SSH/Telnet as 'root' with the admin user password and run the following command.

'fdisk -lu'

The first partition should start at 256, not 63 as shown in my example.

You'll need a clean install of DSM in order to have the Diskstation automatically format your dives using the 4k advanced format. More info on data migration on the Synology website here.

Using ESPEasy with Home Assistant via MQTT

Preface: I've just started playing around with Home Assistant on a Raspberry Pi and exploring the world of MQTT to control devices on the network.

To comment out a whole section in one go: Highlight the text you want to comment out and use CTRL + Q. If you do this at the start of a line, it will only comment that line. CTRL + Q is toggle mode (comment on/off). CTRL + K will allow you to add multiple comments one after the other.

How to check what entities are filling up your Home Assistant database

If you use the Home Assistant MariaDB add-on, this tip will show you how to query the database so see what Home Assistant entity states are triggering the most, filling up your database. What were going to do: Install the phMyAdmin add-on for MariaDB. Query the MariaDB database. See what entity state changes have the most action. Paste the code below into the SQL query box: select entity_id,count( * ) from states group by entity_id order by count ( * ) desc; And if you're using the internal home-assistant_v2.db instead, you can use the SQLite Web add-on to achieve the same thing.
