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.
As mentioned before I bought a pressure washer. But what I didn’t expect is the anti-mould bathroom spray to be so effective on the brick. As this is a rental house I shouldn’t even be doing this but I’d rather clean what I can instead of waiting for the not-so-quick to respond owner to do anything about it.

I bought this … Continue reading Swapping out the circular fluorescent lights with “circular” LEDs 2018 (update 2019)
It’s always a mystery what will arrive in the mail. Sometimes the delivery takes forever other times it’s here super fast. The items arrived 9 days from the purchase with free delivery. These items from different sellers must have be packed in a container that was almost full and ready to go or something. In any case I’m happy as the jump wire I wasn’t … Continue reading Colourful deliveries

Attach … Continue reading Home power monitoring with PZEM-004 & home assistant for under 30$! Part 2
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
