Hello! I’m wondering if someone has the skills and time to write an app for this device: Hi-Link HLK-SW16(board) + HLK-RM04-E Module(wifi module) This is a relay module with 16 channels that are controlled seperatly, is this feasable or not possible at all? I want to control all my ceiling spots seperatly or all at once.

To be honest, I would go for a zigbee, zwave or wifi variant for this and don’t use a 433 controller. It will be more expensive but the saying is probably true : you get what you pay for… Zwave, Zigbee and wifi are more reliable then 433… ---

🤔 To description is also talking about wifi… Then it’s just http-calls I’d say… But strange, it’s also talking about 433 Mhz: ![afbeelding](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/4/4f12f9c792df3c389a8ee47f18785ba258f0b3db.png) ---

hmm strange, the module placed on the board is wifi module. As far as I know there is no 433 MHz module. WiFi is fine for my use, z-wave or zigbee would be a possibility but for 40 USD this is a cheap solution if it works. ---

Reviving this old thread to ask if you ended up buying it (or anything else) and whether the app that is now available on the store works or not. > **[Hi-Link Relays](https://homey.app/en-us/app/net.hlktech.relay/Hi-Link-Relays/)** > > Adds support for Hi-Link HLK-SW16 16 channel WiFi/Ethernet Relay I am looking for a solution to start/stop a lot of actuators for underfloor heating, so any suggestion is appreciated, I will also investigate @Erik_M_Madsen 's suggestion. ---
