Or what I need to do to fix it? I'm using GPIO5.\r\n\r\nEDIT: Oh, and I've tried swapping out the IR receiver as I have 7 of them.

You have big plans :-)\r\nI guess you have considered the usual suspects, but heatsources, maybe even a wireless phone or router if close could be a culprit. I noticed that if I hold my SFHxxxx sturdy between my fingers (casing only) I get random codes. Is there maybe another ESP in the vicinity?\r\nNow ofcourse  an IR module shld be ok  without you worrying about all those things but switching any possible electric device off might be  a start to locate the problem.\r\nHaving it breadboarded can also be a source of problems. You may want to try a small ferrite bead in the Vcc, close to the module and a 4.7uF + 100nF behind that. \r\nTheoretically ofcourse the 100nF parallel to a 4.7uF seems ludicrous but some people swear by it to get rid of high frequency garble.\r\nI hope your AnalysIR goods got you in the right direction.\r\nAnyway, summarizing.. my SFH5110-38, works virtually error free, (but it is a 5Volt and I want to go to a 3.3 V) and I see no reason why the TSOP34838 shouldnt work error free. Telltale is that you mentioned it doesnt work on 3.3 Volt, whereas according to datasheet it should work from 2.5. I am sure you are capable enough to wire the thing correctly, but  if you havent, make sure you have that 4.7uF capacitor  over its supply line, just to catch possible short voltage drops"}}
