As a long time member and 250 owner, I am seeking some feedback on a little project for monitoring your boat. I am seeking feedback and interest. I am part of a small team of developers who created this.

Thanks for taking a look.

If you think you can, or think you can't, pretty soon you find out your are right! H.F.

Wow, nice app.
What hardware is situated in the boat to collect and deliver the data? Is it “marine electronics” grade? What is the current draw? Does it require WiFi? Can it use a cellular hotspot? What’s the effective digital bandwidth requirements (hourly data rate)? Can it use text messaging instead of cell data to deliver data packages?
I’ve also been considering putting a WYZE pan, tilt, zoom camera on board to provide real-time video. It uses a 5VDC/1A supply and ambient WiFi.
I like the GPS reporting in case your dock or mooring lines give way in a blow. Or unauthorized users surreptitiously sail the boat.
Temp, humidity, dew point, wind speed and direction? Nice.
Is it NMEA port compliant?
What’s the security protection for the data? Folks might wonder why privacy matters but a drone can be dispatched based on lat-long cords, so you could be compromised. Imagine the Lifetime made for TV movie script...
Can you add a bilge water sensor? I can imagine a graduated scale showing inches of water or percent sunk.
Depth gauge interface?

Last issue: I’m not certain to what extent this post may be judged as a “commercial message” and as such may be viewed as a violation or bending of the terms of use on the Forum, but to the extent that your message was couched as “hey look at this cool thing that I’m working on”, rather than a “call to action” to make a purchase, I will leave to the Officers and/or consensus.

Good luck with this project.

Thanks, Last Issue first, I was up front using my actual 8 year old credentials for this forum post. I was just seeking feedback, we actually built it for ourselves initially (Covid Project), but it came out great and we want to see where we want to take it.

Its one box (4x3x3) that connects to the sensors, one for each thing you want to monitor (Fuel, Water, Holding, Bilge) using the standard 33 - 220 ohm level sensors (If you just hooked it to the Battery you would get Geo-location, Tide, Weather and Battery Level). The device is Cellular and reports 4 times a day. This version is not NMEA complaint. The data is stored in the Amazon cloud, a team member has a Masters Degree in Cyber, so we do take security seriously.

We do support a Bilge sensing, using smart learning so we learn the normal running pattern of your bilge and Alert you for a off normal condition.

We are working on finalizing production hardware

Thanks for taking a look.

Phil, I suspected that you were keenly aware of the implications, however, decided that the benefits outweighed potential harm. Me, personally, I’d rather know about something useful than not know, or worse, have some pushy salesperson target me.
The hardware is key on this, as are the gozintas and gozouttas. Both new and old NMEA protocols should be included.

Cell is critical as WiFi vanishes the minute the boat leaves the harbor.

A text interface with a settable time interval would be helpful too, in case folks wanted alerts when certain events take place while they’re not using the app.

I assume the prototype is using an Arduino and Zigbee? Slick marine compliant packaging is key.

I’d volunteer to do some beta testing however I keep it simple - handheld GPS, no chart plotters, no weather instruments beside a barometer, and handheld anemometer.

Best of luck on your project.

No we did not use an Arduino, we spun a custom interface board to handle the I/O and married it up to a PyComm module for mobile/cloud development and testing. We are now swapping out the PyCom for a new Cellular module (Not publicly Released yet). As you mentioned a local interface makes sense and we are considering a Blue Tooth communications for that.

We considered NMEA, but we would need to power all that stuff up to take a reading. Our goal was to keep it simple and have the knowledge before heading out to the boat (Gas Level, Battery Level, Environment, GPS Location (From the GPS location get the Tide and the weather forecast).

I will keep you in mind for testing, thanks for the feedback.

I like your approach. I’m pretty good at breaking SW, so happy to help.
