Not to hijack this thread, but would you mind if I picked your brain, @automayted? I have a Smart Oil Gauge to measure my heating oil that I'd like to monitor the readings of in HomeKit. I found a Node-RED import code that I used to scrape the readings from the webapp of the oil gauge. I'd like to pass that info to Homebridge, but I'm having trouble. I have Node-RED running inside HA, and I'm using NRCHKB to emulate HomeKit devices. HA displays the scraped values in US Gal perfectly well, but I'm not sure the best way to pass that info into a virtual HomeKit sensor. I can get the virtual HK sensor to show up in Homebridge, but it doesn't contain the gauge readings. Do you have any experience doing something like this/have any thoughts on how I might go about it?
For actually exposing the sensor to HomeKit, Homebridge is great. I’m a big fan of MQTT-Thing and have not yet found a replacement for all it can do; Home Assistant HomeKit support is good, but lacks many features of HB with MQTT-Thing. For this reason, I’d suggest you simply publish the “battery level” to the topic setup for the contact sensor in HB, add an apply function based on the low battery level, and you’re done.
