Home automation
Introduction I have been experimenting with solar panels, Home Assistant and my electricity meter lately. This French meter from the utility is called Linky. It provides a small power supply (130 mW) and a serial link hidden via amplitude modulation.
To avoid using batteries, I built a prototype that harvests this power, demodulates the serial link, and feeds the data into an nRF52 development kit. It works well enough that I never bothered turning this messy setup into a proper PCB.
I recently did a proof of concept on shutters automation by hacking the remote
control: the idea is to wire the ESP in parallel with the remote control
buttons.
My remotes are Bubendorff 41677 but it should work with a lot of other remote
controls.
I have a great Rika pellet stove, but despite all the
embedded electronics, it is unable to warn me just before the pellets tank is
empty. As I already have my own low-power wireless devices and home automation
tools, I just added a distance sensor and designed some enclosures.
To use my dashboard, I wrote some Dashing jobs to be able
to query some values from my InfluxDB database.
I recently discovered Dashing.io, which is an easy to use
dashboard, which seems to fit my needs :
