Speech generation with Node-RED
Speech generation with Node-RED: the house reads notifications aloud so I stop picking up my phone 50+ times a day.
Making IFTTT (If This Then That) talk to Node-RED
IFTTT is missing WebHooks, so here is how I made it talk to Node-RED and trigger my flows from any IFTTT event.
MQTT topic tree structure improvements
Redesigning my MQTT topic tree structure – research, Tinkerman’s article, and the layout I settled on for my home automation.
Monitoring my home automation system uptime
Free uptime monitoring for my home automation system with UptimeRobot – a notification when the house goes dark, whatever the reason.
Duck DNS updater in Node-RED
Dyn and No-IP got too commercial, so I moved my dynamic DNS to DuckDNS with a small Node-RED updater flow.
Improving my home automation system’s Data Quality
Improving my home automation system’s data quality – filtering the garbage readings that quietly break downstream logic.
Presence detection using phone’s WiFi and Node-RED
Detecting who’s home by pinging the phones’ static DHCP leases from Node-RED – 15 minutes of work and pretty reliable presence detection.
Domestic hot water for free
Domestic hot water nearly for free – my hacked Daikin air-to-water heat pump captures heat in both heating and cooling modes.
Re-vamping my Daikin Internet Air-conditioner controller
A new IR blaster shield for the uIoT gateway – SD slot, FTDI pinout, TMP36 sensor, and a re-vamped Daikin Internet AC controller.
Soil moisture sensing revisited
Soil moisture sensing with just the ATtiny’s internal pull-up and an analog input – no external resistors this time.
Software only solution for feeding weather data to emoncms
Feeding weather data to emonCMS with software only – no hardware, an online weather source covers humidity, pressure and wind.
Monitoring of my heat pump performance
Instrumenting my home-made Daikin heat pump hack with sensors – constant logging to prove whether the conversion is actually efficient.
Hacking Daikin split type air conditioner into air-to-water type heat pump
How I converted a Daikin split air conditioner into an air-to-water heat pump for heating, cooling and hot domestic water at my house.
Custom defrost algorithm for Daikin heat pump
My Daikin heat pump defrosts on a dumb 45-minute timer, so I built a custom defrost algorithm that only runs when actually needed.
Control Daikin air conditioner over the Internet
Adding Internet remote control to my Daikin FTX71GV/RX71GV based heat pump – house heating and cooling from anywhere.
