A screenshot of the temperature graphs from our sensor at home showing it going from 45˚C at 15:53 down to 33˚C now at 16:13 (and it's still dropping even as I type this description).

Well, the southerly has certainly arrived with a vengeance.

A screenshot of a Grafana dashboard showing a gauge panel with the air quality index at 3 (it ranges from 1-5, 1 being good and 5 being very bad), and two spark graphs showing the equivalent CO2 (currently 761 parts per million) and the total volatile organic compounds readings (currently 258 parts per billion).

My ESP32 hacking has continued and I've updated my code to support the ScioSense ENS160 indoor air quality sensor! It measures eCO2, total volatile organic compounds, and gives an air quality index value based on those two readings.

Given that you can daisy-chain I2C devices to connect more than one to a single board, I also changed how my sensor reader repo works and now you can specify multiple sensors and it'll read from all of them and send each reading to a different MQTT topic. So now we have the BME280 temperature/humidity sensor AND the ENS160 air quality sensor hooked up to the ESP32 in the lounge room, and of course I've added a section on my Grafana dashboard to display the data. 😁

My next stop is to bodge together some wiring so I can use the outdoor (nice STEMMA QT connector) BME280 sensor on the same board as the outdoor (standard pins, not I2C) PMS5003 air quality sensor, and not have to have two separate ESP32s for the both of them.

A screenshot from my Grafana dashboard showing two "gauge" type panels, one for the dew point and one for the atmospheric pressure.

I did a bunch more hacking on my ESP32 sensor reader code today, deployed the new BME280 into "production" outside, and got my Grafana dashboards updated! And I was able to do it completely successfully without needing to actually plug the ESP32s into my computer to update anything, the remote-updating code worked a treat.

The new sensor is remarkably close to what the Bureau of Meteorology is reporting: the sensor says it's 17.5˚C, 95% humidity, dew point of 16.6˚C and atmospheric pressure of 1017hPa, versus the BoM that says the temperature is 17.8˚C, 94% humidity, dew point of 16.8˚C, and atmospheric pressure of 1019hPa.

A screenshot from my Grafana dashboard showing the current temperature and humidity. Outdoors it's 24˚C and 28% humidity, and inside it's 24˚C and 53% humidity.

After the week+ straight of rain, this day could not be more perfect if it tried.

A screenshot showing a bunch of multi-coloured panels with sparklines behind them showing current temperature and humidity readings for the four AM2302 sensors we have, details of our power usage and solar production, air quality, plus the maximum and minimum temperatures for today and the total amount of power we've produced, consumed, imported from the grid, and exported to the grid.

A screenshot showing a bunch of graphs for the temperature/humidity, power usage, and air quality.

I've been having entirely too much fun overhauling my dashboard in Grafana this weekend.

A screenshot of a Grafana dashboard showing the current outdoor and indoor temperature and humidity, with a sparkline behind it, plus the consumption and production of power pulled from our Powerwall, and a complicated graph showing all of the flow to and from the battery and solar panels and grid.

Ok, I think my Grafana home dashboard is pretty much finished. The power-related data now matches the colours that Tesla's own app uses, and the colour of the temperature changes as it gets hotter or colder!

Oh shit, I just discovered Grafana. I... may be here for some time.
