Having trouble deciding on products for another application. I’ve successfully deployed your i2c enabled relay board using node-RED on Raspberry Pi4. Good stuff. very reliable for Temp (heater), pH (solenoid valve) and Level (pump) control.
I have the following: 4 24v/12W LED lights (Ecoxotic Stunner Strips). I want to be able to Dim each of the LED lights on their own channel. So, I need a 4 channel board to accomplish that. Looks like I need an extra step/components to get me to the final 24V output though…(Ecoxotic makes a cheap dial dimmer https://www.amazon.com/Ecoxotic-60-watt-Inline-12-volt-24-volt/dp/B006QOLKIU/ref=cm_cr_arp_d_pdt_img_top?ie=UTF8, but I want it controlled within an App in Node-RED, over i2c). Again, this is simple dimming… no color mixing… as the LED strips are arranged in a fixed 8000 temperature… I just want soft starts, soft stops through dimming… run to a schedule in Node-RED.
I also have the following 4 12v/8W Wave Pumps (Hydor Koralia 12v minis). I want to be able to slow down / speed up each of the pumps on their own channel. So, I need a 4 channel board to accomplish that. (Hydor makes an inexpensive and expensive wave controllers, but I don’t want all of those features…like syncronization betwen multiple pumps for wavemaking… that’s over kill… I just want to control each pump independevntly with an App in Node-RED, over i2c). My sense is you have boards that I can directly employ…
I’m very comfortable with i2c, very comfortable with Node-RED, and I’m pleased with the quality of the products that I’ve used from you thus far… I just want to select the correct boards and supporting components.
