Node-Red dashboard to control the BYD PV storage battery
Node-Red dashboard to control the BYD PV storage battery behavior over Modbus TCP. Storm is coming and power failure is likely? No problem, force-charge the battery, including from grid, and put it on hold for emergency power backup purposes. Neat 🙂
Node-RED solar power forecast plus
Using Node-RED's node-red-contrib-solar-power-forecast-plus contribution to plot (light blue line) the estimated max PV generation in ideal conditions for my location/panel orientation/time of year; seems pretty accurate so far. Useful to know what theoretical maximum I have.
Node-RED deserves more than this

Node-RED with mutual TLS authentication
Secured my #Node-RED with mutual TLS authentication through my own CA and self-generated certificates; I have to present a client certificate in order to be allowed to use Node-RED.
ESP32 OTA firmware update using MQTT over SSL
How my ESP32 nodes do OTA firmware updates over MQTT with SSL – a firmware notifications topic tells them when a new version is out.
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.
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.
DIY Internet of Things Fire Alarm
Wiring a 9V smoke alarm into my home automation system with a Funky – SMS, Pushbullet and email alerts when it goes off.
You watch too much TV
Measuring my son’s actual TV time by logging the TV’s power draw to emonCMS – house rules are easier to enforce with data.
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.
NodeRED RFM2Pi to emonCMS gateway
Replacing my python gateway script with Node-RED: RFM2Pi packets decoded and forwarded to emonCMS in a visual, easy to extend flow.
