Somehow I'm pretty sure I'll end up buying it anyway regardless of the amount of other controllers I already have laying around

Re: New chip ESP8285

I too completely missed the news on the new ESP8285 but looking at the articles about it, wouldn't the ESP32 be a better successor?

Astral port/alternative

Is there a port or an alternative for the Astral package? Given it's dependencies I'm guessing a port is out of the question. My goal is to port some code which I wrote for a Raspberry Pi to an ESP8266 so it can check sunrise/sunset. The use for this is for my aquarium, I recently bought LED lightin...

Re: WeMos D1 Mini - DHT22 shield

By the way, those DHT11/22 sensors also warm themselves up if you take the measurements too often. You can see that all the lines on your plots climb up, slower or faster. This is actually mentioned in their datasheets. True and I can't blame them for that, they didn't design and manufacturer the D...

Re: WeMos D1 Mini - DHT22 shield

This seems like they're trying to sell me a solution for their design flaw I would not see it like that. The base is just a base and a mostly usefule for the mechanical integration of WeMos applications. The fact that it shows both a D1 and a temp sensor might be intentional, but just one of its po...

Re: WeMos D1 Mini - DHT22 shield

Perhaps some insulative material between the two, like foam or some thin ceramic, would help. Looks like there's plenty of space. Since I ordered a lot of sensors I'll try to make a test setup and plot the results. I should have enough to test multiple simultaneously with different methods of isola...

Re: WeMos D1 Mini - DHT22 shield

Slightly yes but not as much as the shield directly on top of the ESP8266, 19.3 to 21 so ~1.7c rise vs 0.3/0.4c with the rest of the sensors. I'll pick it up tomorrow and try to edit the code so that one of the MCP9808 will go into sleep/shutdown mode. The difference should be 0.1mA vs 200mA so I gu...

Re: WeMos D1 Mini - DHT22 shield

You can clearly see the DHT22 #1 rising way more than the rest
