I honestly wouldn't know how to work in this summer without that portable AC of mine... Yes, it costs power. But I only run it when I'm working, only in the office, only to a 25°C target, and it's the most climate friendly option I could find back in 2019 too (R290).

Really happy about an efficiency improvement today! Took the Flir One & scanned my setup for heat creep. Turns out the outlet is fairly well isolated, but the hose turned out to be leaking some air & also radiating heat. Duct tape + blanket ftw! Achieving 10+°C difference now!

And thanks to everyone who pushed me in the direction of a dual hose conversion again. I'm still not convinced I can make that work in my room & window layout, but considering the heat & energy prices these days I'm going to give it my hardest try. Wish me luck.

Definitely consider this (accidental*) dip to 23.4°C with an outside temperature at 34.5°C (measured on the north facing front) my biggest win of today! 😊

* Why accidental? Too low target temperature set 😬 Doesn't exclusively happen with 3d printers 😅


@foosel Oh that's cool! A Graphana dashboard of temperatures around your house?!

How are you collecting the data? Do you have any device recommendations?

@tim I really need to write a blog post about my home automation setup 😅

I have a Home Assistance instance running that interfaces with some self built sensor hardware (ESP8266 + BME680, powered by ESP Home) as well as off the shelf stuff (mostly Zigbee based Aqara multi sensors via Zigbee2MQTT). HA then pushes various data into an InfluxDB from which I then graph it via Grafana. Below is a screenshot of the whole environment dashboard.

@foosel That is incredibly cool! Maybe one day I'll attempt to build something like this!

Yes, you need to write a blog post. ;-)
I'd be very curious as I'm working on similar monitoring since quite some time, with a moderate number of T-Sensors talking to an Arduino, but my gnuplot does not look that cool...

How do you measure power consumption, BTW? - some modern meter with uplink or reflective sensor on analog meter?

@ceha @tim I monitor it individually with power monitoring capable smart plugs flashed with Tasmota. I sadly have no easy to monitor overall consumption (renter with ancient meter in the public basement), so I'm slowly building up device specific monitoring instead.

Data flows into Home Assistant via MQTT, from there into InfluxDB and then gets visualised in Grafana.
