FAQs

Please view our support page to find out more.

What is TRMNL's return policy?

PAYMENTS ARE NONREFUNDABLE AND THERE ARE NO REFUNDS OR CREDITS. Refunds or credits may be provided on a case by case basis such as in the event of a damaged or mis-delivered physical good from our online storefront.

Are there ongoing costs to using TRMNL?

No, every device includes lifetime access to the web platform, in addition to various open source projects for self-hosting. However, TRMNL defaults to refresh every 15 minutes, and faster options are available for a small fee.

How does TRMNL actually work?

On the TRMNL website you connect as many plugins as you'd like. Every few minutes, your device wakes up and requests another screen from your TRMNL playlist. Devices connect to your local WiFi and you can configure detailed working hours or sleep schedules to see what you want, and when.

Do I need to know how to code to use TRMNL?

No, hundreds of plugins (growing weekly) make it easy to see your schedule, the weather, upcoming sports scores, and more with just a few clicks. If you do want to build plugins however, there are simple developer SDKs and tutorials to connect 3rd party apps.

Long wait between updates but good quality

15 minutes minimum between Tempest data updates is a long time to wait when wx events are howling. Otherwise it is well built and not power hungry.

Good job.

it's OK

Very good, after you figure it out

I have done away with all of my other weather station displays in the house now that I have this. I think it gives me the info my wife and I need/want. The setup is frustrating and not at all intuitive. They need someone that can write a setup manual, it takes work to make it work. But, once it is done it is great.

Value not worth the cost

If all you want to know is the outside temperature then it is perfect. The rest is unreadable from a distance. What you get for the cost is not worth it including having to pay for a subscription to get faster updates which seems ridiculous. You can buy an android tablet and install the tempest app to see more information, immediate updating (for free) and larger screen for under $90.

Took some doing to get it linked to my PC and was not able to link to my phone. Wish it showed all the information the Tempest Weather Station shows.

Underwhelming

Update rate is slow, not easy to program. Overall, not worth the cost as the Tempest app is immediate and up-to-date.

Too small to read on the wall

I guess I should have looked for a larger size for my kitchen wall. Also, I thought it would show the same data as I get on my phone Tempest app. Live and learn...

Will not update

I only have one app installed, the Tempest Weather Station app. Since I got it set up, it does not refresh the screen unless I manually press the button on the back for 3 seconds, and then most of the time not even then. I have had to reconnect to my wireless network, which worked for a day or so and then reverted back to not updating on the screen. When I look at the online app it shows it appears correctly, most of the time. This is not at all what I expected. It is not a monitor screen for Tempest at all. Throwing it in the trashcan most likely.

Comprehensive Technology & Easy to Install

I have had a few different weather station brands over the years. By far the Tempest with TRMNL are the best. Accurate advance alerts on my iPhone for lightning coming to my home. So far, the forecasts on temperature and rain have also been accurate. And it alerts me when it's raining at home, and great comprehensive weather data specific to my home. Was very easy to install and setup. Had a question for technical support and they were wonderful to deal with. I completely recommend these products.

Nice idea

This is nice, but always an issue connecting to the wifi, resetting it all the time. Will go back to just having the app on a smart TV

Weather info too small except temperature.

Novelty but might break useful

Setup is extremely difficult and I'm a geek. Some of the plug-ins don't work, like NOAA weather map. Tempest wx app shows OK but don't like the wx station so it won't be on this device. Power between charges is excellent to date.

Perfect!

Device is well built, very easy to see, easy to set up, has options for hanging and a stand, or you could easily add a frame. I love that it’s capable of displaying calendars and so much more as well as my Tempest data. The TRMNL is a very useful device and well worth having in the home.

Love the device. Perfect for our bedroom

This is an amazing display. Since it doesn't use backlight it is perfect for a bedroom where more light is a bad thing!

We love knowing what our weather station is reporting before we get dressed for the rest of our day!

Had great hopes...

Product fell way short of our expectations as well as the as the Terms of Service per David at TRMNL HQ. The TRMNL has two issues that we came across that should be addressed. The battery, while fully charged, only lasts about 48 hours while displaying our Tempest Weather that we have set to refresh every 15 minutes. And the TRMNL has to be reset on the back almost every 4 hours in order to keep current on the weather for its 15 minutes refresh setting. It is a great idea, we just believe it's not ready yet. And the email we received from David, lacks just about everything. Our message - Procedures for returning? It just isn't working like we hoped. Every 4 hours or so we have to reset it so it will update the Tempest weather playlist screen. And we have it set for 15min refresh. We have no issues with anything else on our wifi. His message -
Hi there, thanks for reaching out. As per our Terms of Service, we do not offer refunds since we're a startup - which I know feels strange in our world of Amazon returns. Nothing to try and figure out what was going on, no assistance what-so-ever, no suggestions. We will not and cannot recommend this product. If anything, it needs to be removed from selling until they figure out what they are doing. Again, it is a grand idea. We love the idea of what it can do, it just isn't worth it.

Unintuitive and dysfunctional

Interface for setup is very clunky. Changes take to long to refresh to programming is difficult. It does not refresh as set. Tempest should not be associating with this product. It does not live up to its quality and ease of use. How do I send this back?

Great Addition

Very good addityion to my Tempest weather station. It avoids having to access the Tempest app to see the latest readings. I am 77 years old and definitely not programming capable but was easily able to do the required setup and configuration due to its simplicity. The display is clear and wireless so no issues with power cords. It was initially hard for me to set up up update frequency, but that was unfamiliarity with configuration processes and with the supporting email was able to work through setting it up to update every 15 minutes from the Tempest unit. Nicely done and dummy friendly. Wish it was larger, but I understand larger sizes are coming soon.

Nice add on to Tempest Weather Station

I'm using this as a display for my Tempest Weather Station. I really like it. I'd give it 5 stars if the setup was easier. I couldn't get it working on a 5 Ghz Network - but could in a 2.4 Ghz. Linking it to the Tempest App took much trial and error but I got it working eventually. Linking to a couple of other apps was easier. It's only visible in the daytime - would be great if some natural or reflective background could be incorporated into a future design. The screen is smaller than I thought but still very easy to read. I'd definitely consider buying another one for use elsewhere in the home (with some added features).

Exactly what I needed, simple display for my tempest

It's always been my number one gripe about my tempest is no display for current weather conditions. Now this is handles that and it's wonderful. Plus this device and display many different things. Love it. A little expensive but not too bad.

high contrast display of Wx

It's convenient to view the Tempest data without pulling out my phone. But it would be nice to customize what parameters are displayed.

As Described

The device was quite simple to set up. I have added additional plug-ins in addition to the Tempest weather station. The refresh rate is 15 minutes but for an added subscription to TRMNL the refresh time can be reduced but for most (there are many) plug-ins the refresh time is not an issue. So far, I am pleased with the device. I wish the TRMNL personnel success in their endeavor.

Works, but difficult to setup

Setup was not straight forward and took several resets. Screen would hang indefinitely. It’s confusing that the on/off button does not do anything visible. Eg turning it off leaves screen on, giving the impression that the button is broken. Removing something from the “playlist” and doing a forced update seems to do nothing. Eventually it does seem to catch up with your configuration and doing its thing. Wish the tempest wx app could be configured with your own api key and do direct updates at a faster than 15 minute frequency.

Nice to ‘see’ my Tempest station data, but ...

wish it was a bigger display … current size is fine for a desktop, but way too small to hang the terminal on the wall like a 8x12 frame size. Also, the Alexa app now REQUIRES us to say Open the Tempest Skill Set, and only then can you ask for the weather from your local tempest…cumbersome and NOT as useful as it used to be with Alexa. What that has to do with the terminal is that at least I can see the local weather station data…if I get close enough to the terminal.

Functional - Very cool

Really like this unit. Note that it does have the capability to refresh faster when using Tempest (5 minute intervals).
The only thing that could improve is a better wall mount system - such as one that could mount to a single gang box.
