I have a greenhouse which I try to make it smarter with a Raspberry pi, Blynk, Node and my phone and also a question: how can I send a value read from one of my temperature sensor, via Node Red, in a Blynk Table Widget?
I read that PeteKnight make something similar with the entrance door log on his house in Spain, but I cannot see the code.
Thank you in advance,
My example from Spain is probably going to be confusing, as I’m constructing a date/time string for my “name” field and then using the msg.payload for the “value” field. That looks like this:
msg.add = [year+'/'+month+'/'+day+' '+hour+':'+minute+':'+second , msg.payload];
I’ve not included the code that declares and builds the
It might be simpler if you show me what you have so far, and explain what data you want in the table.
Thank you! These two lines solved my problem.
Try to make a table to save de min, max and medium temperature during one day, from midnight to midnight, based on the value send by one sensor. It is very hot here in Romania, I have a greenhouse who has automated windows, fans, sprinklers and blinders and I wanna know if my algoritms who control them are efficient.
