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.
The home assistant issues are never ending. A trivial matter for once. After getting an Amazon echo and enabling the wemo emulation in the tasmota software in the sonoff basics, errors errors everywhere. I stumbled across this while searching for something else. https://www.google.com/amp/s/amp.reddit.com/r/homeassistant/comments/8utc9j/psa_wemo_warnings_and_lost_connection_fix/ The next day Screw it. Today I decided to trash the database again (automation?) as the state history graphs are flatlining and … Continue reading Wemo lost connection
Another mystery package arrived recently. When I have so many things on the way it’s always tough to guess what it could be given the haphazard nature of the packaging. This package is not much different, it’s pretty poorly packaged. Thin and light. And unsurprisingly also arrived in a damaged box. As the titles gives it away. Voila it’s the LED ring. I bought this … Continue reading Swapping out the circular fluorescent lights with “circular” LEDs 2018 (update 2019)
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
Picture of wires from blog In my old leaning house I have one live wire going to the light switch. nothing else is in the switch box. Now I thought that this would be because of the old leaning house that I’m in. However upon asking around it would seem as thought this is common in new constructions as well. This image goes to doesn’t … Continue reading Japanese wiring isn’t automation friendly.
Although it’s a different light. There has been an update to the way I have integrated the sonoff basic. It no longer hangs off the edge but is rather unnoticed and sitting inside despite the 40c operating limit. See post here Living in Japan fluorescent lighting in house is everywhere. Although I’ve gotten used to it now it was strange at first. Virtually all … Continue reading Sonoff *in fluorescent light housing.
Received sonoffs a week ago. Been having an inordinate amount of trouble getting the portable arduino ide software working. It would give me various errors with no solution. Installing the full version for some reason made the problems go away. The unstable jumperwire connection I had made to the sonoff didn’t much help. A little electrical tape to wrap the pins helped. Having the whole … Continue reading Sonoffs flashed
