epanet-js VS openmiko

At the start up I work at [0], we use an open source library I developed to run hydraulic models of water networks in JavaScript [1].

A hydraulic model may be between 1-10MB and the simulation results can end up being 100+MB of time series data.

Other vendors with proprietary engines have to scale up servers to run their simulation engineers and will store and serve up results from a database.

Having everything done locally means we only have to store a static file and offload the simulation to the client.

Because we've architected it this way our hosting costs are low and users generally have faster access to results (assuming they're running a moderately decent machine)

I'm a civil engineer and I wrote an open source library that compiled a C library to javascript for my own personal projects - epanet-js [1]

A water utility in Spain spun off a start up called Qatium [2] and they used my library as the engine of their simulations and asked me to join.

I created a handful of application around water engineering/modelling [1], plus an open source library to run the simulations in javascript [2].

A water utility in Spain spun off a start up to create a similar web based water modelling application and they used my open source library.

They approached me and I joined them and have been able to maintain the open source library as part of my role.

I work as a water engineer, specializing in building hydraulic models so water utilities can simulate their network.

A big part of that is calibrating them which can be time consuming, you look through hundreds of options. I create a few web based apps to help grind through these tasks but ultimately they were for my own use as a consultant to close projects quickly.

I did pull out the engine as its own open source library for other to use, and that ended up helping me get my current role where I can now maintain it and be paid at the same time.

I've built a few open source apps and few other little projects to help automate my workflow.

There are only a handful of providers of modelling software, most are commercial and one recently sold to Autodesk for $1B.

Not sure I'll convince the industry to change but I'm enjoying tinkering around and making my own small difference.

Have a Wyze Cam V2 running openmiko. I can pull the feed via the camera's IP, but Klipper (Fluidd, Mainsail on BTT CB1) shows like below. Additionally, moonraker-timelapse throws an error. This was working fine until I tried Hyperlapse. Now I can't wrap my head around this

I'm running MainsailOS, and a Wyze cam v2 running openmiko. I have Tailscale installed on the Pi for remote access. In Mainsail config, I have the camera configured via private IP. When I access the web control panel externally, I do not get video output. Is there a way to get this to work? I do not think there's a way to connect the Wyze cam to my tailnet.If it's not possible, have any good recommendations for a good, cheap, wide-angle (110 degrees FOV or better) camera I can purchase? I wouldn't want to spend more than $25 for one. Quick search yielded this one, but don't know if there's a Klipper-community recommended one that everyone uses.

you wish lol. the mod allows you to get highest possible resolution video out of it without all the compression pixelation. its super easy to install. but it does take a little bit of linux knowledge to edit config files and stuff. heres the link if interested: https://github.com/openmiko/openmiko

I bought a used Wyze Cam V2 relatively cheap and installed OpenMiko on it for example.

I have a WyzeCamV2 running OpenMiko firmware, which supports (and I have configured for) H264 RTSP streaming. I can view the video stream through VLC with the url rtsp://192.168.1.199:8554/video3_unicast. I am executing the command docker run -p 8081:80 --name mycamera -e AGENT_CAPTURE_IPCAMERA_RTSP="rtsp://192.168.1.199:8554/video3_unicast" kerberos/agent:latest on my host. The agent seems to run fine and I can connect via browser. With our without AGENT_CAPTURE_IPCAMERA_RTSP... set, I cannot add the RTSP stream; no cameras show attached and when I try to connect one via dashboard->settings, it just spins. The logs aren't really helpful (see below).

OpenMiko is one example.

That's why I only use cameras flashed with open firmware: https://github.com/openmiko/openmiko

If all else fails, you can flash different firmware and use them locally. I'm using [OpenMiko](https://github.com/openmiko/openmiko) on my Wyze Cam v1 (I'd assume there's a similar open-source project for the v3), and Wyze themselves publishes an RTSP firmware. Without a bit of technical know-how and some supporting hardware (namely a router than supports OpenVPN) you won't have access to the stream off your local network, but you can stream locally with VLC Player.
