or you can use a dht22 that does 0-100% humidity also

in theory you should be able to connect any sensor to a esp like a LI-190R Quantum Sensor and read the data

i ;looked into this last night you can update the firmware like a esp microcontroller with arduino and use the pins to control stuff directly to, the basic sonoff has an extra pin as well it looks like people use esp easy to do this how to cammect ip camera feed to node red dash...

so is this Home Assistant on a pi 3 is it ? with some ip cameras and the rest temp, humidity and lights using sonoff's ? looks good i was looking into trying to something like this with node red but this looks like a great starting point

is there any info on how this is wired up i see you have a wire not going into the sonoff at all . is the sonoff only on the neutral wire ? does this operate using mains dimming method ?

im interested in doing this too with my esps do you have details on how you set this up and the code perhaps

interesting these are £0.11 each could be usable i wonder how many you would need to match or better reds etc i also wonder if adding a few 625nm reds would add a jump in the red peaks with photomofic effect

ok great sounds good to me will wait on an update
