temperature and humidity

[grssll]

Hi, thanks for the excellent work and explanation on the code. I've managed to implement your code with BME280 and 0-10v GP8403 component to control whirlybird fans. Trying to modify the code to use with both temperature and humidity but so far no luck. Any chance for the guidance in the right direction? Coffee on me to keep u up! Thank you

Thank you for the compliment, I'm happy to hear my project was/is useful to you.

It's unclear what help you are looking for and I'd need some more info: -- What have you done so far -- What, if any, errors are you getting -- How have you configured the new components

Also, is this for DAC you are using? 2-Channel I2C DAC Module (0-10V)

[grssll]

What I'm trying to achieve is Lambda automation based on temperature and humidity. For example in the morning temperature drops and the fan turns off. But at the same time humidity rises and it would be nice to get automation based on two readings. BME280 provides both temperature and humidity. I'm using Dfrobot dac and it works perfectly on your Lambda code and temperature from bme280. I hope it's little bit clear. Cheers George

Take PCT of temperature as u did before, Take PCT of humidity, combine them together and use that for the automation.

Yep, I get what you're trying to do. Please send me your code (minus any passwords etc), I'll take a look at where you're at and try to add the humidity for you.

Looking at your code: line 174: - Calling "id(set_humid).state" but there's no "set_humid" ID

It's unclear why you are using two BME sensors, two fans and two i2c busses yet setting and checking the temperature twice and humidity only once.

[grssll]

Sorry, line 140 should be "humid". This is just the tryout code to work out humidity and temperature combined logic. Esp is in the server rack and two fans in different parts of the house with separate sensors to get more accurate reading.

[3ative]

So with that correction, is it working now?
