Home Assistant 4-Wire PWM Fan Controller Prt 2 - Flash & Breakdown

[@fibranijevidra]

Wow. This is how the code should be explained. Just amazing. Thank you very much.

[@3ATIVE]

Woohoo! Thanks, Fibra! Your comment made my day. I'm glad the tutorial was a helpful companion. More exciting content coming soon!

[@fibranijevidra]

@@3ATIVE Homestly, you made my day too. I was smiling for joy while watching it, and now I go to play with it. Have a nice day mate.

Love your videos and the way you explain things. This video has 1000 views, it's actually 100 viewers having to watch the video 10 times to understand it.

[@3ATIVE]

👍I'm glad you liked it Konrad, thanks. Sorry I went a bit fast on this one, there was a lot of info to get across and I didn't want a 30 min video. 😉

[@phil18boydell]

mine is built and installed in my wled psu. cannot wait till part 3!😀

[@3ATIVE]

Excellent. I'll try and get Part 3 filmed today.

Hi this has been a great project and I've had it working for a little while now to cool my media center. i have noticed that the esphome code wont update now as the sensor info needs to be changed, could you please confirm this and maybe help explain how. love your videos and many thanks.

[@3ATIVE]

Thanks for the support, I'm glad you are enjoying my videos. As for the code changes, I did make (I think) all the necessary changes. Check this video's description for the GitHub page link.

[@bryantubb5680]

Hi thanks, I should have looked around more I did find the info and it helped. All working now and thanks again

Fantastic! I've used this to build an oil pumped burner that's controlled with a temp sensor to control the oil flow. Working spot on. I have an LCD with temp and set temp however I'd like to add the pump/fan speed percentage like shown on the web server under actions, but for the life of me I can't get it on the LCD. Can you point me in the right direction?

[@3ATIVE]

That's a great use-case. For getting the Fan speed percentage. As shown in this video, line 52 (of my ESPHome Code) timestamp: 07:23 You can either replicate that line to another template sensor and use that for your display... Or, Within the Fan Component itself - you have "fan.on_speed_set Trigger" this will also give you the "speed". More info here: esphome.io/components/fan/#fan-on-speed-set-trigger

[@nivagc1]

@@3ATIVE Thanks so much for responding so quickly, I've been on this for the 3 hours and no further along. I've mange to get the speed on the log output using the fan.on_speed_set Trigger. but can't get my head around pulling the "pct" variable created in the Lambda section timestamp: 07:23

[@nivagc1]

Sorry I guess that was a statement and not a question! Could you elaborate a little on the "replicate that line to another template sensor and use that for your display" I've tried adding a binary sensor: platform template with an ID and Name of pct

[@3ATIVE]

@@nivagc1 No worries... 1st: Using the "pct" was an option. Seeing as you have "on_speed_set:" working, here's how to use it. 1. Make a template sensor, give it a name and an ID. E.G.: - platform: template id: fanSpeed name: My Fan Speed 2. In the fan: component add the "on_speed_set:" to give the new sensor a value. E.G: on_speed_set: - sensor.template.publish: id: fanSpeed state: !lambda return x; Now every time the fan speed changes, so too will your new sensor... you can this new sensor (id: fanSpeed) for your display.

[@nivagc1]

@@3ATIVE Hello, thanks again for your reply. I've added the code and now I am able to see a fan percentage on my LCD as well as in the web server.....However! the script has stopped working. if I change the set temperature value the fan speed dose not change, also the fan will not turn on. I have tried to change the id and names of the sensor and template just to see if there is some sort of conflict. If I comment # the new code out it all works again.

[@riksteen4933]

Hello. Is there also version for a humidity sensor Instead of the temp sensor. , voor shower or bathroom fan thank you

[@3ATIVE]

I haven't made a version... but, you could replace the DALLAS Sensor with any number of sensors, E.G.: * DHT11 * DHT22 * BME280 - To name a few.

[@Johnsmith-uc9df]

Great project thanks. Could I add a BME280 sensor to the esphome code instead of the dallas sensor.

[@Johnsmith-uc9df]

Im getting a error when i validate [on_value] is an invalid option for [sensor.bmp280]. Please check the indentation.

[@3ATIVE]

Of course you can....

[@3ATIVE]

Oh wait, you already did - LOL As for the automation. Like any other sensor "on_value" should work fine. Check your code to see if it's correctly formatted.

[@Johnsmith-uc9df]

@@3ATIVE Thank you is working now i didn't have the on_value inside the temperature indent or something like that :/

[@clairerovic]

Going to buy a fan, just to do this project

[@3ATIVE]

LOL - Have fun Claire 👍

[@iourigoudkov8138]

Is it possible to read temp from external sensor?

[@3ATIVE]

Absolutely, just adjust your code accordingly.

[@Yiveytube]

Thanks for the video! 👍 Looking forward to part 3. For a total noob on ESPhome, how much change to this would I have to do if using DS18B20?

[@3ATIVE]

I hope you enjoy part 3 too. FYI a DS18B20 is the temperature sensor I'm using here. "DALLAS" is just what ESPHome calls it.

[@73fug]

Play this video at 0.5 speed and it nearly makes sense. thank me later

[@3ATIVE]

🤣🤣🤣🤣👍👍

[@momuskk]

What about reading fan speed? I'm wondering it is possible to read fan speed using esphome? In 4-pin fan there is one pin to read fan speed (tach).

[@3ATIVE]

Sure, the Tach output of the fan can be read using the Pulse Counter component in ESPHome. I chose not to add it here as it was a lot of code for something we already had... Plus the chances of a fan failing is quite slim.

[@delboytrotter7902]

I'm gonna build one.....i've not got a use for it, but it's sexy as fook, so that's reason enough for me ! lol

[@3ATIVE]

LMFAO - Love it 🤣
