Sea temp?

I'd suggest that the water depth would be more intuitive if put the other way up; i.e. depth increasing down.

Have they swapped the sea temperature reading from °c to °f without changing the "c" to "f"?

interesting comments folks 
@RAI, @Alicatt : there was a thread a few months back with everyone slagging AIRMAR for the DST transducers. Well mine works for depth (seen there), speed (whenever I clean the log wheel and for the next week or so). Temp though stopped working couple of years ago. Pulled the boat out in May, a week later temp started working (obvs transducer temp bit dried off...) Back in the water, immediately stopped. Now a month later had a 12h spell of "working" Bet water now in the marina is around 26-27C, decided to go for almost 60C oh well...
@AntarcticPilot : interesting comment, didn't actually think of it, you are of course right. Problem is that Grafana is rather restricted in the way it presents data, took me endless hours hacking trying to get a rudder like gauge. Need to spent time developing your own gauges and no matter what adwuk thinks, I don't have THAT much time to spare See if I can revert values and go from top to bottom!
@adwuk:
surprising little effort needed to get the four screens I have for monitoring conditions on board. Since all data are on the N2K bus anyway (that wasn't trivial but was done anyway over the last 3yrs), a raspberry pi3B, a CAN-HAT on it, VenusOS Large (with signalk) is all that's needed. SignalK takes N2K data and sents them to my work server in an influxDB and Grafana screens are crafted picking the influx data as stored on the server.
Note last few days boat locked, some hatches open, some serious heat wave down here, lower helm temps reach 38+C, two fridges really suffer to cycle even at 3.5 and 5C.
posted pic as I found the almost boiling water temp amusing especially since field was empty for the last month.
cheers

Beers in the saloon fridge are going to get warm soon?

true, but beer in home fridge is fine! It's so hot out there that I don't even bother to visit the boat (500metres from home...)
Next week we'll probably be out in the nearby isles for a week or two and by then I'll open the salon windows and temps inside will drop dramatically and beer will be fine

I'm pretty sure I would just turn that mess off and sail the boat. With all that business, how does it actually benefit me?

You could just multiply the depth by -1!interesting comments folks

other than remaining sane throughout last winter lockdown, if you have to ask, then the answer I guess is it doesn't.
thanks for reminding me why I post so little in PBO.
@AntarcticPilot: yes can be done, as shown in the pic below, but then you have to live with negative values in depth which is a tad counterintuitive. TBH, the reason I put depth in that page was so that I can easily check from home or office when waters are low and wind picks up as at that combo boat moves more in it's mooring (med mooring, stern cleats and 70kg anchors with thick chain and 20m of rope at the bow) There were occasions that tender was almost touching the dock with v.strong southerlies, so if I'm around I can go and check. Following pic apparent wind is from the N so pushing the boat away from the dock.
