I have an sensesp coding question.
I started this project using hatlabs HALMET firmware code considerably modified only using the tank part of code that used the analog converter modual.
In the original code a constant scale factor was set before the statement:...

Has anyone found a flow meter that works on small (10HP/7.5kW) outboards (for fuel)? Most I've seen have a minimum LPM that's a lot higher than a small outboard consumes.

Bilge counter setup question. Hi all, I'm using Halmet digital inputs to read when our bilge pumps activate. I have this data in SK and written out to an InfuxDB. I'm interested in other peoples solutions, but I also have these questions for my current solution please.
Q1, how do i count the number of times the bilge runs and display in a graph, date vs times activated?
Q2, the database seems to record the state of the bilge switch several times per second. I really only want to know when it activates and for how long
Q3, what do people use for external alerting, SMS/EMAIL/push, and how you configured? i have permanent internet aboard
Thanks, Colin...

Hi, I bought this tachometer for my YANMAR 2GM20, everything works but the value is always 0. I connect one wire to D4 and the other to GND. I followed the example in SENSESP repository.
The signal of the tachometer is sinusoidal.

Can someone point me to example sensor code that uses multiple dallastemperature sensors.

We have a generator that only has shutdown sensors for exhaust temp, water temp, and oil pressure. What is the easiest way to get actual values for those parameters into Signalk?

Does anyone have a CAN to USB device that they like with good linux drivers? I thought I had one, but I can't build the ubuntu drivers for it.
big__col - I cant get N2K data into my SK serve...
I am getting other data into SK server from non-N2K devices, so i believe the Halmet to SK connection is working. It appears to only be a problem with N2K data not being fowarded to the SK server, or maybe i've missed some config on the SK server.
I've used the default/example firmware from Git, untouched.
Steps performed:...

Any recommendations for a way to determine when a small outboard is running? 8HP/6kW, no access to any spinning parts (except the prop). I was thinking maybe an IMU to detect vibration. Pull start, so no electrical/alternator, but maybe I could insert a voltage sensor between the magneto and the spark plug.

Having problems with SensESP and N2K connection. B&G Zeus can get some engine RPM readings from the ESP, but lists the device name as
??? and without any device info. Also I can't verify the actual data displayed yet since the boat is on land now, but at least the Zeus showed correctly 0 RPM. What might be the problem?
Here's the relevant code:

What’s a good Hall effect type sensor for reading rpm from the flywheel via a magnet? Ideally some analog type that can be powered from the esp32 pinout

@Matti Airas I need serial on the HALMET without using USB. I need receive NMEA0183 and have RS422 to TTL module already. Is it possible?

@Matti Airas, is there a way to measure the supply voltage on the engine HAT without using a separate analog input? I have a fuel tank sender that is piggybacking the existing wiring and so the reading changes depending on the supply voltage.

@Matti Airas not sure if it's the right channel, but I have the first generation of sailorHAT on a raspberry pi 4b. Would it work on raspberry pi 5?

I'm thinking it's not, but is the sensesp stack smart enough to handle two signalk servers? I've got one on my pi but I recently added it to my cerbo for the easy remote access. I'm guessing that it'll just select the first one it sees to ship data?

Anyone built an anchor chain counter? I'm thinking of just epoxying a magnet to my windlass and adding a reed switch to count the turns along with a voltage sense (divider) to tell me what direction it's going.

Has anyone looked at using temperature sensors to measure bilge water depth? I've been thinking it could be an interesting way to do it with solid state hardware. (no switch to foul) I believe that it's very rare that air temp matches water temperature.

if you had a usb hub you'd have a teeny sensor network 🙂
