Wrong date and time on Raspberry Pi running Domoticz

I recently booted up an old instance of Domoticz home automation software on one of my Raspberry Pi's with a PiFace interface. I noted that the time and date were out by three months and even though I had a valid network connection and pinging the NTP time servers was possible, the date and time would never update.

I spent about 40 minutes on Mr Google trying various things and this is what worked.

  1. Login to your Pi using SSH
  2. Ensure your Pi can ping a time server
    ping 0.debian.pool.ntp.org
  3. Stop the NTP service
    sudo service ntp stop
  4. Force a time check
    sudo ntpd -gq
  5. Restart the NTP service
    sudo service ntp start
  6. Check the date and time
    ntptime

    Should now report back the correct date and time?

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. Learning curve is a bit steep but worth the effort as MQTT is very fast. The hardware and software tools I'm using are as follows: 2 x Sonoff relay units 2 x NodeMCU Boards ESPEasy firmware (must be version 121 or above as that contains the MQTT 'retain' flag option. Home Assistant software on Raspberry Pi2 MQTT Test Software: PC: MQTT.fx Android: MQTT Dashboard

My Notepad++ tricks when editing YAML files in Home Assistant

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.
