Ok. Can not find that on Github only the master/ dev branche where is it located? Sorry I found it while sending this message This is the one? http://www.letscontrolit.com/downloads/ ... 47_RC8.zip
Re: K-Type / MAX6675 build in
So I can still use this _P120_Thermocouple.ino sketch?
Re: K-Type / MAX6675 build in
Ok the hardware tab is now showing the SPI part. Give it a try later-on Thanks.
Code: Select all
Init SPI: (Note : Chip Select (CS) config must be done in the plugin)
Re: K-Type / MAX6675 build in
Must still over-see something I guess. Now I get this:
Code: Select all
34710 : P120 : C : 0.00 - F : 32.00
39714 : P120 : C : nan - F : nan
Re: K-Type / MAX6675 build in
Which sensor do you have?
Can you measure between t- wire and ground? Is there a connection?
Is the thermocouple not connectoed to other stuff?
I guess you have to do some more research.

Re: K-Type / MAX6675 build in
Now I got it working. I tried an other MAX6675 module and that worked. So the other module might have been broken. Nice!
Next part is connecting an display.

HI Guys
Does he work with ESP Easy Mega ?
Does he work with ESP Easy Mega ?
Code: Select all
Edit: Yes he works :D , In the first post I can see reported 2 temperature in the plugin P039 only one is displayed How get the second value ?
Re: K-Type / MAX6675 build in
hello everybody, thanks for the information on this topic.
I try to use the sensor but on esp easy the temperature doesn't change, always 30.5°C .. any info about the refresh ?

Hi. I have nodemcu and a MAX6675. Problem is that i only get 0C/32F readings in ESPeasy mega - same as the whose sensor board was disconnected.
What settings do i have to change in Espeasy mega? Enable SPI interface - already did that.
Checked pins thrice, VCC is in 3.3V output...i dont have a clue what is wrong.
Any advice? i already ordered a second sensor board..maybe i got a lemon from china.

Hi, what SPI clock or speed is set for max6675 in SPI.begin() ?
thx

Re: K-Type / MAX6675 build in
maybe a stupid question but I have a max31865 with a P100. Does this plugin also works with this breakout?
Re: K-Type / MAX6675 build in
Hi,
I know this thread is quite old but I try to control my solar system with the espeasy. Is it possible, that the output temperature of this module is in Fahrenheit?
In the screenshot of the module there are 2 temperatures °C and °F , in the actual module I got only 1 value line.
Did anyone already try the MAX31855? If I connect the same PT1000 from the Max6675 to the 31855 the shown temperature value is getting lower as the sensor temperature rises and the values are completely different (Sensor is about 50°C value of module shows 9°)
Kind regards
Max

Re: K-Type / MAX6675 build in
You can also convert the Celcius value using a formula, which is also shown on the system variables page (not present in 1M or testing builds)
Code: Select all
{D}C to {D}F: %c_c2f%(20.4)
°C to °F: 68.72
