When I ordered the USR-TCP232-T2, I also did order some other ethernet modules to experiment with: The Eport E20. These looked better than the USR’s so I thought just try them to see how they work. And so the story began 🙂

Not really needed, yet I wanted to make/design something. I also wanted to try to build something with an ESP8266 (without development board). I still had some SMD components from my previous build: P1 to Ethernet
So I thought, why not a wireless version?
For a long time I’ve used the common P1-USB cable which can be connected to a Raspberry Pi or any other computer. Since the last changes in my network and server setup, I had no server in the meter cupboard. Everything moved to my new office. So it was time to read out the P1 smart meter via the network. This can easily be done via an ESP32/ESP8266 over the WiFi, yet I like to connect as much via wire as possible. So the new challenge started …

What do you do with an old Raspberry Pi? Yesterday I was cleaning up my desk and saw this older unused Raspberry Pi 2 model B. So I was thinking what to do with it? I’m always using my desk computer for printing, while I work on my MacBook Pro 99,99%. So I decided to make a printserver with this old little fellow.

Recently I received the notification that there was a new version for Portainer. Now I’ve most of my containers configured via docker-compose files, which makes it easy to upgrade. Yet never done it without docker-compose files.

After using docker on several Raspberry Pi’s and on my main home-server, I wanted to add som more power to my test environment. So I bought the 4GB Raspberry Pi 4 with an overpriced power adapter: PoE HAT. It costs about 225% of the regular power adapter. Yet as all my switches are equipped with PoE, makes this a lot nicer and cooler to use #nerdmode.

I’m not checking every day my measurements. It’s pure for logging and sending data to my Home Assistant. Yet a few days ago I saw only one bar in the graph: an usage of 22774.693m3 (?!?!) That’s a reading for one day…

First impression: these plugs are small. Is there any room for current measuring?

After using the larger Tuya plugs, I knew there where these smaller better looking plugs from NEOCam. After some small research (a.k.a.: Google Search) I found out that these plugs have also the esp82xx chipset. So I ordered some to test these plugs.

After I bought my house a while ago, I wanted to get more grip on my electricity usage. I knew it was higher than average, as I’ve got several equipment running 24/7. I had some z-wave power plugs to monitor some device, yet not al off them. I know someone from tweakers.net, quindor, who’s created his own WiFi LED dimmer. Recently I saw some of his videos about cheap energy meters running on esphome. He wrote a blog about it.
