demig, do you know if he's applied the update? I posted over on homebrewtalk but no reply yet.

No, the code still formats dates US style. I found the bit of code which performs the formatting but couldn't get it working with what is a simple fix. Will try again.

Figured it out!



If anyone wants the binary image with the fix in it then let me know and I can host it somewhere. Just need to tell me what kind of ESP device you're using, NodeMCU 1.0, Wemos D1 etc.

I have a spare sonoff switch i wouldnt mind loading up with this s/w afaik its a generic 8266-01 with only gpio14 available? but im not 100% on that..

Vito has produced .bin files for the Sonoff and they're in his Github repo

Andy, I've contacted him and he's rolling the update out soon.

I hate the American dates, just spins my head when your doing a fermentation profile! Lol

Sorry was afk drinking beer Beaten to it anyway I see. There is some good stuff coming in this project, the gravity based fermentation potentially using the spindel looks great.

Yea so I heard, loving what's possible with these cheap ESP boards. I just know once I sort the ESP BrewPiLess out I'll be wanting to build a gravity sensor! Lol

Out of interest, if you got one set up, do you use the mechanical 2 channel relay boards?

This is what the Sonoff boards use so if your concerns were about reliability specifically the stability of the device when switching mains then it is fine.

I've read that the relays may cause interference with the ESP and show as spikes on the BrewPi graph??

If you use a digital sensor such as the DS18B650 then it would not be possible.

why wouldnt it?the spike might not being introduced on the data line,a coil de energising tends to send nasty stuff down its power lines, the arc caused by the contacts making and breaking maybe producing enough rf noise to upset the microprocessor ,loads of ways that a dodgy signal could be getting in

For what it's worth, in my controller I use 4 relays with a NodeMCU board wit no issues. I take a median of 5 readings to make sure there's no spurious readings from the DS18B20s.

Not as cheap as coil relays, but if you are suffering with EMF could give these a try.

Is anyone running BrewPiLess in Beer Profile mode ? If so any issues with the unit dropping the Wifi connection ? I've got the s/w running on a Wemos D1 and a NodeMCU 1.0 devboard and both of them drop the Wifi after a period of time. The s/w is still running and doing it's controlling work, it's just lost its network connection and won't re-establish without power cycling the board.

I've noticed the same with my setup Andy. The WiFi is right at the limit of the signal to the shed and will drop out regularly. I changed the WiFi connect routine which enabled it to re-connect.

This is in the main loop:

Code: Select all

if (WiFi.status() != WL_CONNECTED) {
    wifidrop++; //increments WiFi drop counter
    setup_wifi();
    return;
  }
  if (!client.connected()) {
    long now = millis();
    if (now - lastReconnectAttempt > 5000) {
      lastReconnectAttempt = now;
      // Attempt to reconnect MQTT
      if (reconnect()) {
        lastReconnectAttempt = 0;
      }
    }
  } else {
    client.loop();

Cheers,
Jamie
