I need to make a 8 channel 220v power strip. do these components matche together?
NodeMCU LUA V3
8 channel relay
KY-022 IR remote
the reason I chose NodeMCU LUA V3 is that it’s the cheapest mcu I found that doesn’t need soldering
I have something like this in my mind
Yes, but you need to be careful with wiring.
This will save you some time:
what do you mean? because of ac electric shock?
I couldn’t find the module you suggested. the relay I posted earlier is available
since there are 13 pins in total which pins on nodemcu I should use?
IR remote and relay’s gnd and vin share pins or connect them separately?
Actually, Esp8266 has 9 (somehow) usable gpio pins plus TX/RX.
You need them all. And some pins will trigger relays on boot. I strongly suggest to go with Esp32 board. Cost is maybe $1 more…
if you remember I mentioned I live in Iran and I can’t buy from international websites.
my options are very limited
NodeMCU LUA V3 is 3$ and the cheapest nodemcu esp32 is 10$
with that in mind it would be best if somehow I can use NodeMCU LUA V., if it’s even possible
I know it’s not ideal but it’ll do the job?!
Yes.
Use the same pin configuration from the link above for ESP-12F_Relay_X8
With some of the pins that have states that effect boot or change state at boot, you may be better off using 2 8266’s and only use pins that are stable at boot.
Only difference is there will be 2 devices each controlling half.
I’m literally in war zone, Tehran, and they are shuting off the Internet so I need to do configurations ASAP to be able to control the relay offline
for now I got an 4output relay
please tell me which pins are safest for relays 4 pins an which pins I should use to connect KY-022 IR remote
also please give me a esphome yaml code to control the relay with KY-022 IR remote
I know it’s a lot to ask but it’s emergency
Gpios 4,5,12,13,14
That’s not something I can do. You need to receive and record the codes successfully from you remote control first.
these are the code I get
