I wish I’d seen this about 72 hours ago. I ended up doing #1, but not until after I got a Navien certified plumber to come in. He charged me $400 to replace a faulty valve, but never solved the problem of it turning off. Your #1 fixed that. I tried to do number #2, but I still can’t figure out how to push/flip or otherwise do anything with dipswitch #2. Mine aren’t switches…the little white square that looks like a dip switch seems to be just painted on.
Thank you @nikshriv! Amazing stuff. I was able to get this going with the update!
Two things I’ve noticed:
-the integration loses connection anytime my router reboots and the only way I’ve been able to get it started again is by manually reloading the integration on HA
-seems like I can’t tie in the gas usage with the HA energy/gas usage functionality (seems related to this: Expected data source not listed - Home Assistant)
Happy to help contribute here if helpful whether it’s on the above or if there’s anything useful I can provide data-wise from my combi setup.
I’ve experienced the same issue with disconnecting when my router reboots. Should be a relatively easy fix. I’ll work on that soon.
Regarding your energy use issue, I have it working in my setup. Home assistant tracks my total gas usage without issue. Can you find me some more detail about what’s going wrong? Do you have an error in the log?

That’s interesting. What model do you have? I have the NPE-240A2 and it came with the Hot Button PCB. It looks like this:
You could try soldering a wire across #2?
Excellent!
I’m trying to use the Energy dashboard where you can set up a gas consumption sensor (it can then calculate price, etc). I do see the cumulative usage sensor, but this is more energy consumption built-in functionality in HA as I understand it:
Essentially none of the sensors from the integration show up in the dropdown (and at the bottom of the dropdown it says if you don’t see your sensor here to check the link I shared in my prior post).
I have the earlier 240A so I had to purchase the Hot Button separately, which I only did a couple of weeks ago. My guess is that to stay in compliance with CA laws, they no longer included the dip switches to force users to the energy efficiency mode. I get hot-ish water now pretty quickly, so I may not mess with it. If anyone complains, I will do as you recommend with soldering the two points together on #2.
You’re right about the energy management. I know what happened. I recently revamped the sensor portion of the integration and must have changed the device class of the total gas consumption sensor. I’ll change it back and it should start working for you. You’ll have to delete your current configuration, reinstall and log in again.
I did fix the connection issue if your router or internet goes down in the latest version.
It’s fixed. Download newest version. I think you’ll just have to restart HA, no need to delete your current configuration.

I updated to 35cf5fb and restarted HA. Not seeing the cumulative gas sensor in the list.
Hi @nikshriv - I updated yesterday but unfortunately still don’t see the sensor for the Energy management and it also hung again when my router rebooted.
I don’t understand why it wouldn’t be allowed or be discouraged. It’s only doing the same thing as the other recirculation modes.
Yeah, I could have just received a bad one. At this point, though, it’d be easier to solder #2 as you suggested than to go through the process of returning.
Just saw the new update and am seeing the energy management piece and the dropping after a router reboot working now! Huge thank you @nikshriv
Before I go ahead and buy a navilink module, does anyone know how this integration would work with 2 units running in cascade mode? Right now I’ve been trying to use a relay to control the hot button module but because there’s 2 units, things get a little funky.
the “commercial” version is supposed to be able to do that.
anyone figure out how to get data out of the unit without the navilink module? i see they’re out of stock pretty much everywhere and it looks like it’s just an ethernet cable with a special connector at one end.
i’d like to get some data out of it without having to use their cloud-based api.

This integration is compatible with Atlantic Cozy touch Navilink 128 ?
When I try to connect I have “Invalid NaviLink user credentials”.
Thanks for making this. It works well with one Navien so far. I have a second Navien, not in cascade - if I add this one to my Navilink account, will the integration be able to add a second device?
I have a NPE-240A (not A2) and have a couple questions:
- Will this work if I connect via NaviLink Lite?
- Would I be able to control recirc since I do not have an A2?
(partially) Answering my own questions after a Navien field service call to look at my NPE-240A and install a NaviLink Conversion Kit (new PCB & Front Panel), turning it into what I would call an NPE-240A1.5. This was necessary for connecting to NaviLink.
- Will this work if I connect via NaviLink Lite?
Yes, the integration recognizes a NaviLink Lite.
- Would I be able to control recirc since I do not have an A2?
So far, I cannot seem to enable hot button as suggested in this comment (I think his unit was an A2), but I think it’s because I would also need to connect a hot button add-on controller (one of the features included on the A2, but not on A or the NaviLink Conversion Kit…boo!).
@ben1492 In reviewing your comment, I see that installing the add-on controller might still not get me hot button functionality in HA. Did you end up soldering #2 and how did it go?
Has anyone been able to trick an A original PCB (e.g. P12 or P20) or NaviLink Conversion Kit PCB (P23) to think it has hot button functionality without installing the hot button add-on controller?
I have the older A model, so I did indeed have to purchase the hot button add-on. It works great and I didn’t have return/replace or solder #2 dip switch. I set it up to to turn on as soon as a motion sensor detects I’m in the kitchen in the morning. Instead of having to wait 2 minutes for hot water, it’s now only 30 seconds. Honestly, it’s one of those automations I haven’t even thought about since setting up 6 months ago. The key was maxing out the furthest fixture setting…I believe mine’s set at 500 feet.
