Reddit mentions of Lysignal DC 5V 8 Channel Relay Module Interface Board for 51/AVR/AVR/ARM with Optocoupler Protection

Aqara are OK and i've improved my Aqara HA setup by using the DeConz Zigbee hub rather than the Xiaomi Gateway (using DeConz keeps all your data within your network without sending it to China and back).

I don't use any of the GJD controllers (I've no need for them as HA does all that work)

My two main raspberry PIs each have PiFace Digital IO boards installed. These add-on boards give true 5V (rather than 3.3V from the Raspberry PI direct) to trigger the lighting relays. They also present the IO ports in a nice orderly straight line of numbered phoenix connectors.

Here is a link to line drawing of my garage wiring, and a photo of the install: https://imgur.com/a/usUGfJA


The PiFace IO boards have incoming feeds (green lines) that monitor the door reed switches and the PIRs. They also have outputs (orange lines) that connect into Celduc solid state relays that switch my lights on and off. So the combination of reed swicthes and PIRs trigger my floodlights, garage, and shed lights as I move around outside. They then also trigger surveillance station to record CCTV when any sensor picks up movement or a door open/closure.

My garage distribution board in the photos has Din rail mounted 12V and 5V PSUs to power the RaspberryPI, the PIRs and the relays.


I've used (mostly 2nd hand from eBay):

Meanwell PSUs (5V and 12V cheap off eBay) https://www.amazon.co.uk/Din-Rail-power-supply-MeanWell-MDR-20-24/dp/B00MWQEI08


Celduc Solid State Relays (cheap off eBay) - https://uk.farnell.com/celduc/sul842070/ssr-25a/dp/1659369


However in the past I did use one of the cheap chinese relay boards like this - https://www.amazon.co.uk/Lysignal-Channel-Interface-Optocoupler-Protection/dp/B073W6QD9P/ref=asc_df_B073W6QD9P
The chinese relay board worked well but didn't seem very professional
