Yun rev2. Heat relay won't kick in second time

BrandonLee

Hi Andrew,
Today I purchased a Yun Rev2. Initially all looked like it was working perfectly, however, after the heat relay(solid state) turns off, it does not turn back on when the status turns to heat again,
So the auto button is green, and the power button yellow. If I then click the power button to make it green, the heater will turn on, but then it doesn't turn off.
I've tried all the PWM ports.
Also tried different ports for the temp ds18b20
I'd really appreciate any hints.

Thank you

So I have arduino.local now resolving.(I had to use IP address before)
But the still having the same problem. I can control the relay manually, but the auto only works initially to turn relay on. Thereafter I have to manually control turn the relay on/off using the web button. I've also tried hooking up the Yun with ethernet thinking it might be a wifi issue. The "error connecting to arduinolocal" still pops up.

Now I'm stuck and not too sure what to try next.
If I use:
http://192.168.0.110/arduino/digital/D3/1
the relay turns off
http://192.168.0.110/arduino/digital/D3/0
the relays turns on

but the monitor will not turn the relay off.....only on, unless I A) use the xxxx/D3/0 or B ) if I click the "power" button in the monitor.

Hi Brandon, let me do some tests on this and get back with you.

BrandonLee

Thanks Andrew.

I did brew a German Bock lager this past weekend and used the pwm @ 4% for the mash. So even though the relay didn't turn off, I was still able to hold the temperature fairly stable at 68 degrees C.

I look forward to your test results

Hi Brandon, sorry for the delay, there seemed to be a problem with the sketch returning proper JSON in the response. This is fixed in 4.5.1 sketch, you can download a new sketch and this will work now. Thanks again for letting me know. Guessing I would have found this if I brewed more often...

BrandonLee

Very much appreciated Andrew. I'll definitely be making a brew this weekend

andrew

Awesome, let me know how it goes. If you use a Tilt for fermentation you can use my new app. It also supports some BrewBench sensors and soon will support all custom ones you build. https://www.brewbench.co/#sensors

Hi Andrew, worked 100% with the new sketch. Never heard of the Tilt(until I visited your link) but wow, definitely will be checking it out along with your app.

Thanks again for the support
