Has someone thought ( like me ) about Smart-Boat ? e.g. this is one of my living room lamps at home : www.b2net.net/wimbledon/me_l.html( it actually light the lamp when you click ON  and it works with Siri also and I have build all my other things at home using same open source free technology - ( github.com/i4things/NodeAPI/tree/master/examples/ESP8266-01/1CH_RELAY/thing) - cost in the end come-up to £4 one-off per switch. ( have about 20+ , doors, gates, music, timers etc. - and of course had a great fun doing it Me personally I do not like and do not trust Alexa, Google Home, Apple etc. as they monitor you all the time and sometime mistakes happen and also their security is very low... Now thinking about make all my switches on the boat smart also.. e.g. when I want to drop the anchor - just do it from the phone or just tell to Siri to drop the anchor - get anchor up,light the navigation lights, anchor light, almost everything... anyone interested to do something together and experiment ? |

We have a remote key-fob on-off switch on two inside the cabin lights (same frequency) and one separate on-off key-fob switch in the lights on the arch so when we return to the boat, we can turn them on to see the boat and get on & off safely. Here's a link to a product similar to our, yet newer. I'd like to find on that would work from my iPhone rather than a key fob. www.amazon.com/relay-switch-wireless-remote-control/dp/B019B9S21O |

The one thing which I think would be good, is an app which sends any info to an onboard tiny robust computer (Arduino - Pi etc).
This can then possibly interface with NMEA 183 or 2000 and do 'something' as required.
Such as raise lower the anchor (via physical relay) or autopilot control etc.
The dials I did recently was to allow swipe screens on my phone for NMEA data so I can see it whilst below etc. Adding 2 way is simple, and could be good.
Note that there are a fair few facebook groups doing this already, mostly on PIs - and they tend to use signalK as the backbone.

Mike Thanks for the hint yep signalK looks interesting and has some good examples and implementations ... I would wish for a bit more low level binary data format as bandwidth is always important ( in my case most of the packets are in size <= 8 bytes and growing per factor of 4 bytes only) and also want to be able to implement it without need of NodeJS or any other type of web server - just pure C/C+ no OS e.g. easy to be used on simple CPU's with low consumption. My current favorite is ESP32 - 2 X 32bit COREs + one ULP CORE ( ultra low power code) - about 1 year on 50mah ) with proper multi-threaded ( FreeRTOS) implementation and not need for OS. Also in my case I want the back channel also - e.g. I want to be able to control the boat remotely - switch off the lights ( if someone has forgotten) etc. and who know may also control the autopilot, have a perimeter fencing (like a drone) or in case of a theft - e.g. good security, guarantied delivery and simplicity in the transport layer/protocol is paramount - hence I need network key, private key, signing and simple and yet secure encryption - all preferably built-in a simple API supporting multiple transports e.g. LoRa, WiFi. NBIoT etc. |

I would not mind upgrading my home to a "smart home" and so far we just have a couple of Amazon echo hockey pucks and a Sonos speaker with Alexa. But we just have it for music streaming.
As for a smart boat, I'm not so sure I see much point.
What I wished for on my old boat was more things I could monitor whilst onboard. For example I fitted a battery monitor that had bluetooth and an app. It helped me better choose what revs to motor at to charge the batteries and when the charging rate dropped so I could go back to sailing, all from the cockpit.
Now some of that can be done from your MFD but the cost of devices to feed that sort of info into your NMEA2000 network tends to be crazy.
Even before I stopped cruising and started racing, I wanted a way to record NMEA data and monitor my sailing performance. Build polars from my own sailing (rather than the designers optimum numbers) and dynamically maintain them and even report how I am sailing compared to my past performance. An accelerometer, pressure and other sensors to monitor other factors and perhaps calculate sea state. An ability to enter your sail plan (sails used, reefing).
Have it all running from a RaspberyPi at the nav station and a phone/tablet/watch app.
I bought a Raspbery Pi and started to learn Python to look at building such a device, but I lost focus......
A lot of the performance stuff can be achieved with a B&G H5000 system and Expedition or a Nexus Racebox, but Garmin bought Nexus and killed it off and the B&G H5000 system is so expensive that only big budget race teams can afford them.

Same as many others I'm using a trusty old Raspberrypi as yacht server for this&that. Also do not trust putting things into cloud so... the server doesn't have any public IP (I don't get anyone anyway by default from my provider, using a 4G/LTE router, because of dual NAT) and do a ssh reverse to a known (by me ) jump server. From outside I connect to it via the jump server and all communication goes via this encrypted link. In boat is a BMV712 connected via a usb<->VE.direct cable (pitty Victron only embrace opensource halfway, the monitor have bluetooth but they do not publish protocol on bluetooth side). Battery Temperature(°C) Voltage(V) Current(A) Power(W) SOC(%) 0 11.0 12.80 -0.475 -6.00 99.60 There is also a YDWG-02r which acts as wifi<->nmea2000 (or really Raymarines version of it ) plan is to add something like YDCC-04 to be able to switch power off/on on certain items. For example turning heater on so the boat is warm and cozy by the time I travel to it. As I plan to move up to 48V system voltage, it would be very nice to have a true 48V variant of it. Vasko, make sure you have a span of like 9-56V for your switch. I would be customer directly ;-) |
