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
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.
2019.07.13: After a few months leaving out, sensors that fluctuate many times a second things seem to be stable. The sensors that fluctuate rapidly are the BRUH type as they send change info if a certain threshold has been met. (2 or 5% change in values) ____ For months on end after I increased the number of iot devices drastically the state history graph would … Continue reading Recorder histogram flatline testing
As per blog 75.3 to 87.1 I did an update of HASS.io in a manual fashion. There were many factors which pushed me to do so. One of these was the history graphs were flat-lining. This seemingly minor detail bothers me tremendously, given that I no longer use Grafana at the moment (I thought I was pushing the RPi3b too hard so a clean minimalist install … Continue reading HASS.io History graphs flatlining
Sunshine… I thought that this movement false positive was only a cheap ip camera thing. Alas no… Come to think of it two sensors are starting to act up. Upstairs bedroom and outside. The bedroom sensor used to give me false positives due to a bad power supply. The outdoor one now seems to alert a lot as the shadow of the house grows and … Continue reading RCWL-0516: More outdoor issues with the PIR AM312
