Huh, oddness with the DHCP. Do you know if it actually was connected to the WiFi at all and didn't get an address or was it just not doing anything. For some reason that I don't understand, I had to setup the network on a couple of my devices (8266/esp32) twice. The same information, I just...

Yeah, same thing. You'll have to supply the SSID (and password if applicable). You don't give it a MAC address because it is hard coded. I do all mine with DHCP and then define each MAC in the DHCP entry table on the router.

On my ESP32 I had to hit the flash button before it would take it. I think my 8266 was the same way. It would time out every time I tried it, but if I hit the flash button it would load right up. For reference, these are the two I'm using in my setup (keg fridge and ferment fridge)...

Looks good. Just watch out for the vortex foaming issue. That is why I put the hole down the tube so it didn't try to suck right near the surface.

That is all dependent on the tubing you are using. Here is a picture of the tubing that came with the Fermentasaurus floating pickup with a 1/4" nut on it, seems to fit fine. On the other side is some other tubing that I use for floating pickups, and I think you would need a 3/8" nut for that...

I wouldn't say they 'free floated'. I just went and retried it with a 1/4 20 nut and it must have been bigger than that because the 1/4" one didn't slide on. I just found some nuts that slid on but weren't loose, so they just stayed where they were put on the tubing.

No, in my case I would get a little beer dispensed and then it would just turn to all foam. The higher the pressure in the keg, the more likely it would be to foam out. My theory was that, as the rate that the liquid went into the tube increased, the more likely it was to form a vortex to the...

Fermenting under pressure can stress the yeast and create flavors you don't want. I assume you are talking about doing this in a Unitank type setup (maybe a keg), but if not having the carbonated beer at 30PSI makes the transfer much more difficult since the CO2 will want to break out of...

A few things: 1) I have the spunding valve from AIH (homebrewing.org) and they go up to 60PSI 2) When I transfer to the spunding vessel (keg) I often see a delay before the pressure starts to rise. I attribute this to the CO2 that broke out of solution during the transfer, and so the liquid...

I have many of those floating pickups. They can have big foaming problems if they form a vortex to the surface while dispensing. I was able to defeat that by cutting a hole in the silicone tube just behind where it sticks over the float tube.

I have a 16x24x8 panel and I wouldn't want to go any smaller than that. I wouldn't consider my requirements to be particularly large and I only have a little extra space now. A lot of it gets eaten up in wiring channels and just spacing between parts. Empty space in your panel won't bother...

I think if it came to either the problems of oxygen pickup due to transferring still (fully fermented out) beer or letting it spund at room temp, I would take the latter.

Yeah, I'll just toss some resistors on it. It certainly isn't any obstacle to my application, but I thought I would mention it.

Even with nothing connected, they have the state "ON", so the pin must be low. That seems backwards given the open circuit nature of those GPIOs. I'm measuring it with a Fluke DMM, so that has an input impedance of 10M which shouldn't really effect the pin voltage assuming a pull up of 10s of...

Yes, I have GPIO13 and 14 set as inputs and active low. I'm using GPIO16 as an active low digital output to drive the relay, which seems to be working as expected. I have some resistors I can use for pull ups, I was just hoping to use the internal ones if they were there. Here is a screen...

Here is a question on the new firmware (v45). I am using an esp8266 to control a power outlet. The setup is pretty simple, there are two float switches, a 2 relay board, and the esp8266. There is a pump is in a bucket and when it fills to the top float switch the pump turns on and runs until...

Did you strip the oxygen from your water with either pre boiling or the yeast method? That, along with the trifecta, go a long way toward the reservation of the wort. If not, the yeast method is really simple and quite effective.

I don't really have much detail at the moment. I just got my new kettles and so I'm starting to play with how exactly the system is going to work (now that I can try things for real). The setup is sort of a HERMS, but using a CFC to do the heating and the chilling supplied by water from a...

I have a question on ramp rate control. I looked in the manual and wasn't able to find anything that controls this directly. What method is being used to control the rate of the ramp when going from one set point to the next? I looked at using the script to keep changing the target for the...

I have used a cheap SSR similar to the one below to run my keg fridge for years. That is a similar kind of load I would think (compressor)...
