Easy to use. So far so good. *by K***H on December 23, 2019* I purchased this device several months ago to automate some equipment in a greenhouse--lights, a fan and vents. I am finally getting around to setting it up.The documentation is minimal, but to the point. I was able to get it connected and toggle the relays in a few minutes. I'm going to do some testing with various loads on the device over the next couple of days to see if it's reliable enough to run unattended.It's supposed to be able to switch a max of 125V/12A, so that will cover all the things I need to do. I'll be using DC and AC power. I'll post an update after I've got it up and running and had some experience with the thing.~~~~~~ Update #1So far I've had it in service for about 1 week and it's working fine. It controls some low power DC and AC devices including LED lights and linear actuators. It seems pretty reliable so far. It boots quickly, acquire and IP address. Broadcasts UDP "hello world" messages and responds to TCP messages. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/26921296-8-channel-ethernet-relay-controller-support-poe-and-rs485-open](https://www.desertcart.co.uk/products/26921296-8-channel-ethernet-relay-controller-support-poe-and-rs485-open) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
