Light doesn't turn on

[rwr88]

First of all: thank you for this great project!

But i've encountered the following problem: when I turn on the machine, the light doesn't turn on. Only when I turn on the steamfunction, the light turns on. Seems to be affecting only the light, because the boiler is warming up. Is this a problem, or is this just the way it should work?

And as a result of this, is the only way to check if the temperature is okay, is to acces the dashboard?

Speaking of the dashbaord, is the way to acces the webinterface just go to the ip-address of your raspberry pi?

Thanks in advance for helping out

There should be an indicator light on the relay, does that turn on and off?

[rwr88]

No, that doesn't turn on

I've got the MAX 6675 module in stead of the MAX3185. Does this causes the problem? I can upload pictures if you like?

Can you please indicate where we go wrong? You help is much appreciated

I still hope you have some time to leave a comment, because this whole project is no on hold cause of the relay that doesn't turn on.

Thanks in advance

Can you post a picture showing the relay and the pi clearly showing which pins it's connected to? I can then share some shell commands you can try to see if we can get the lights to turn on and off.

I've connected the pins, hopefully done correctly, exactly as you prescribed it. Perhaps good to mention that I've used a pt100 sensor, and, already stated above, the max6675 amplifier. If you need more info, I can provide that.

I’m also having a similar problem. My temp sensor is working but when the temp hits the threshold it doesn’t trigger the relay. At first I thought the relay may be under powered 5v but I tried with a logic converter and still nothing.

I have measured the pins (26) using a multimeter and the voltage never drops to switch off the relay even when the temperature is reached. Any ideas. Thanks very much.

Can you try wiring it as seen here: https://i.imgur.com/TPqJUAM.jpg
This image shows the pins that the relay should be connected to, be sure you have the orientation of board correct: https://imgur.com/a/ttWtOmE

This album shows more pictures of how I have mine wired: https://imgur.com/a/3WLVt

Hello, I have wired mine like this. I can get the web server to read my temps on :8080 but the pi doesn't switch off the relay. I have tried using different pins from 26 but still nothing. Will it matter that I am using a MAX6675 Breakout board?

Adam, move the purple wire next to the white wire and give that a try.

Will I have to change the config to pin 37? Thanks.
