I recently read a Panbo post regarding stuffing box temperature taken using a TM100. I love the idea! So I thought I'd get a TM100, a USB100 to program it and I'd be good to view that temperature data on my eS127 and Axiom 7 via a SeaTalkNG to DeviceNet spur cable. It seems I was wrong. For what seems to be a few lines of missing code (maybe not?) I've learned that Raymarine doesn't support the PGN's required and then also doesn't support labels to have meaningful names. It would appear the only real answer to this is to install a DSM410 at both helms. At least I wont need a USB100 any more, but cost is going to increase substantially and helm real estate reduced.
My question is - am I missing another solution out there? Is Maretron the only one doing this? I want to measure 6 (really 7) temperatures - stuffing box x2, engine coolant x2, engine room temp, and generator coolant (currently no gauges and almost 50 years old).

Hi Steve, that was me talking about putting a TMP100 on my boat's shaft seal (as part of my entry about the boiler install). The job is done but I won't be back to the boat until April to see how it behaves underway.

At any rate, there may be a way to get your temperatures to show on your Raymarine screens (though not great). Using your USB100 and N2KAnalyzer set the TMP channels for a common temperature "source" like Sea Temperature, Outside Temperature, Inside Temperature, etc. The list is here:
https://www.maretron.com/support/manuals/TMP100UM_1.2.html#_Toc432500242
Those sources (or labels) are part of the N2K standard for the Temperature PGN, and I'm pretty sure that Raymarine supports at least a few of them. So your eS127 and/or Axiom might show your stuffing box temp as Inside Temp but you would know better.
Raymarine seems more limited in regard to somewhat unusual sensor data display than Navico, Garmin, and Furuno, but none can really do the Maretron system justice. For instance, regardless of what source you specify for a TMP100 channel, you can also set a custom label name that will be remembered in the TMP and available to any Maretron display. I sure wish those labels traveled further but to my knowledge they don't.
You can even write those labels on a Maretron DSM display, though it is a very tedious process. Which is why you should probably keep the USB100 but get at least one DSM for display and also alarming. Staring at a shaft seal temp is not the way to go when you can set very specific alert and alarm conditions that get your attention on the DSM screen and/or with an ALM100.
Here are some past entries about this stuff, but I do plan a more complete and up-to-date entry once I've tested my latest TMP100 install.

Thanks Ben. I don't have any of the Maretron gear yet, this is just in the planning/purchasing phase. From what I can tell, no one really does the extensive alerting and alarming that Maretron does. I'm going to have to use restraint to not buy every module they sell. At this point I think I'll start with a TMP100 and a single DSM410 for the main helm. I'll add another DSM410 for the flybridge next season. I believe this means I will not require the USB100 as I was only getting that to program the TMP100, which can now be accomplished via the DSM410.
How are you monitoring your engine coolant temps? Did you just bolt the ring temp sensor to the block, or did you use an immersion sensor in an adapter?
Steve, I do have a TMP100 ring sensor on Gizmo's engine block, and find an alert based on that value very useful, but I also used Actisense's EMU1 to get analog engine gauge values into NMEA 2000:

I'll need to check my water hose diameter in the spring, but I'm thinking of doing it as suggested here: https://www.maretron.com/support/knowledgebase/phpkbv7/article.php?id=643
Nice find, Steve, and it looks like those adaptors are easy to find:

PS Have you also looked at Maretron's CLM100?
https://www.maretron.com/products/clm100.php
It's capable of monitoring temperature and many other things, using supposedly easy-to-source 4-20ma current loop sensors, more here:
https://hackaday.com/2017/07/19/the-4-20-ma-current-loop/
I've looked at the CLM100 - I used to be in the process automation field and have used 4-20mA devices with PLC's - not hard, but the sensors can be expensive. I'd love to have a hall effect sensor on my shafts. Maybe after I see success with the TMP100.
My boat is one big project (still renovating the interior)...I have to be careful not to take on too much each year.
