TL;DR Change the mqtt topic. —– BACKGROUND: A project I have yet properly posted was a tasmota NODEMCU with a relay and a bunch of sensors. (Bruh plus sonoff and a bit) I suspect after using too much power and having the breakers trigger, something went weird. The relay would simply from then on turn itself off. Searching online. There’s the physical dr zz https://youtu.be/31IyfM1gygo … Continue reading LWT ghosting the quick and dirty fix.
There is much more serious news with regards to typhoons. This isn’t to belittle the importance of actual news, obviously. Ugh…Typhoons. In 2018 my wireless ipcam died. It was replaced by a whole NVR system for the outdoors. (Which has been a non iot post in draft mode for a year now) Countless dht22s and now the latest victim, my new BME280 which was outside … Continue reading Super Typhoon 11 (2019) AKA “Krosa” claims another sensor.
In my kitchen I have 2 sonoffs. One in the overhead ceiling lamp (the wall switch didn’t have the ground/earth wire) There is another sonoff attached to a wall mounted “tv” from reusing a pc monitor and a firestick 2nd gen. In order to save a sonoff and place it elsewhere as well as centralizing all the iot in one spot I though I’d take … Continue reading Combining multisensor and sonoff
Last year I’ve had to replace the DHT-22 outdoor sensor several times during the peak and constant high humidity levels and the rainy season. I had discovered the BME280 sensor and read many good reviews. Wemos D1 Mini and BME280 Temperature, Humidity and Pressure Sensor Compare different i2c temperature and humidity sensors (SHT2x, SHT3x, SHT85, ..) Mentioned previously part1 part2 part3 I recently converted my … Continue reading Wayyyy too hot and humid but the BME280 troops on.
Part 1 / Part 2 Finally the AHT10 and BME280 sensors have arrived. First step soldering pins. Got to unwrap my newest soldering iron. Then loading up tasmota on the nodemcu. (The same one that was already outside) Despite all the OLD instructions to edit the useroverride section in the sonoff.bin I simply downloaded the newest 6.6.0 tasmota as per instructions has i2c support for … Continue reading Replacement of the DHT22
Part 1 As I await my replacements parts I figured I’d try a few ideas to attempt a recovery of the defective DHT22. The first thing I decided to do was to remove the DHT22 from its partial enclosure. (Sensor part was exposed) Reconnected the sensor node and …. it’s still stuck at 99% humidity. I blew on it and the temperature changed but not … Continue reading DHT22 tinkering.
For over a year I would replace the DHT22 (or its small brother the DHT11) outdoors after a few months if I cared to do so. It’s located in a cutout of a small Tupperware container strapped under my deck roof. No rain can get to it but the roof is no completely opaque and lets a fair amount of sun through. Although the temperature … Continue reading DHT22 is useless outdoors: replacement.
