P1 WiFi Wemos v2.x
Update Portainer on Docker #2 (Portainer CE)
Recently I saw I had an update pending, which didn’t go away after updating. I already had the latest image on my Docker. Then I saw it was an other image it was revering to: portainer-ce.

In the last few months I’ve made over 40+ P1 modules. Each module I’ve sent to the customer is fully tested on my own P1 meter. That means each time I have to disconnect my own, to connect the to-be-tested module. Now I’m lazy and don’t like to connect my own module each time (read: I just want to make/start a new project 😂). So I figured I wanted a splitter of which each port acted like a P1 interface.

After making several Wemos D1 model, I started to thinking… “Should I’ve done that different..?”. I made a jumper selector on it, as a safety that when powered via USB, that power couldn’t go into the P1 port. One of the first test with a diode wasn’t that stable due to a too low power drop. And as my stash pcb’s where shrinking, I thought to fix this and make it better.

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?
P1 to ethernet
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.
