The Telos Mesh app allows you to wirelessly connect and control up to several hundred Growcast or Telos LED systems from a single smart device and brings revolutionary new functionality to growers using Bluetooth mesh technology. The app has been designed to be secure and all commands are encrypted. Once your lights are connected, you can enable Privacy Lock mode to hide the network and make it completely invisible to anyone searching for a Bluetooth network. Precise PPF Control Telos Mesh gives you precise control over the PPF output of your Telos LED. You can use the scroll bar to adjust the output from 0-100% or directly enter the desired PPF level into the app. Compared with fixed increments on traditional dimmers, using Telos Mesh you can set the exact PPF level to suit the plant and grow area for amazing repeatable results. Automated Scheduling You can easily create and apply schedules to single lights or groups of lights and get rid of mechanical timers once and for all. The optional sunrise and sunset mode helps to ease the plants transition between light and dark periods. The app displays all the key information on the grow lights page so you know exactly what is happening without having to open the grow tent. Advanced Functionality Use the Rooms functionality to group Telos grow lights together and apply different PPFD settings and schedules to all the systems within a single area quickly and easily. This is ideal for controlling two different grow areas with plants at different stages of the life cycle. ## Key features - Wireless control of multiple LED systems - Precise PPF adjustment (0-100%) - Automated scheduling with sunrise/sunset - Room grouping for different grow areas - Encrypted commands for security - Privacy Lock mode for network invisibility ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/telos-mesh/id1601766328/reviews.md ### 5/5 — Great app *2023-01-22, version 2.0.12* I have enjoyed using Telos Mesh so far, it was easy to connect the lights with Bluetooth. The app gives lots of useful options to tweak the light and schedule settings so it’s perfect for my growing room. Developer keeps adding new feature updates as well so that’s good. ### 1/5 — Doesn’t work *2022-09-12, version 1.0.12* Absolutely useless. Can’t connect lights - ‘provisioning failed’. ### 3/5 — Amazing hardware, but the app can be a bit confusing *2022-03-22, version 1.0.12* Getting to grips with this app took a little doing. The app interface looks sweet, but there are UX issues that still need addressing. Enabling Bluetooth connectivity and operating the unit from the smartphone I found a little too fiddly. The in-app visual clues to addressing user errors could be clearer. I got there in the end, but not before several setup resets and restarts. ## Frequently asked questions about Telos Mesh ### What devices does Telos Mesh support?
