16 channel wifi relay module Hi-Link HLK-SW16


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.

Link to the product, also available on aliexpres:


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…

:thinking: 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:


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.

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.
