HAP-NodeJS VS node-red-contrib-homekit-bridged

Doing a bit of digging, I found the Charaacteristic definition in https://github.com/homebridge/HAP-NodeJS/blob/master/src/lib/definitions/CharacteristicDefinitions.ts. I'm still a bit new to Typescript... what would the best way / place for me to modify this Characteristic? Do I need to just make this change here and basically run a custom version of Homebridge?

Well, the API only provides m3 values, and the plugin you suggested is only displaying 2 decimals instead of 3 in homekit (most likely a homekit limitation; since in homebridge 3 [and even 4] decimals are listed, and the accuracy of the sensor seems to be 0.0001 - as listed on https://github.com/homebridge/HAP-NodeJS/blob/master/src/lib/definitions/CharacteristicDefinitions.ts )

Or more specifically https://github.com/homebridge/HAP-NodeJS/issues/993

HAP-NodeJS Pull: HomeKit Secure Video #920

My goto place regarding this is the HAP-NodeJS repository

They're related in that u/koushd contributed https://github.com/homebridge/HAP-NodeJS/pull/904 to Homebridge, which was completed and merged with many of their commits in https://github.com/homebridge/HAP-NodeJS/pull/920.

Yeah this appears to be the relevant discussion on it: https://github.com/homebridge/HAP-NodeJS/pull/918 I guess Raspbian does not ship with avahi by default.

I looked at libraries like HAP-NodeJS or HAP-python, but those seems focused on:

Hello, I’ve been running homebridge for well over a year without issues and recently I’ve been getting “no response” from any device loaded through homebridge. Restarting homebridge does nothing to improve it nor does restarting the docket container, but restarting the raspberry pi 4 it is running on can occasionally help, but this lasts for maybe a day before the no response returns. The only error I see occasionally in the log is due to one plugin for the jablotron security system. Disabling that plugin does not fix the issue. Everything is up to date. The accessories work fine via the homebridge web interface. I have other HomeKit devices that are created via node red and https://nrchkb.github.io running on the same Pi that work fine. Scrypted cameras work fine too. I had not added or changed anything to the system for months. The no response just started out of the blue.

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?

I used it not myself and maybe you already have it but have you seen this? https://nrchkb.github.io/

I’m not sure if homebridge is the right platform for this. I might suggest node-red and https://nrchkb.github.io/

I'm running Node-RED on a Raspberry Pi and use node-red-contrib-homekit-bridged as HomeKit bridge. The dashboard is done using node-red-dashboard and some CSS hacks. The buttons I press to trigger HomeKit scenes are exposed as stateless programmable switch. So i can assign scenes and accessories to them using Home app.
