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.
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.

Although the temperature … Continue reading DHT22 is useless outdoors: replacement.
In Japan power outages are rather rare. Sure there might be one with a storm or typhoon but that’s a maybe. Recently on a calm autumn day the power went out without apparent reason. (No act of god) Luckily I had my raspberry Pi and thus HA, on backup power. Some might say this is overkill. I prefer to think of it as insurance. Besides, … Continue reading Battery backup for Home Assistant? Overkill? I used to think so.
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. Black with decades of disgusting dirty rain … Continue reading Spray cleaning brick-wall fence
