    Vumatel Fibre + ISP for IPv6

    Nice! Router is running OpenWrt, just works. Good job, folks!

    Port MTN mobile to VoIP?

    The point of the eSIM is that you can have more than one in your phone without it consuming a SIM slot that the new provider might want to use.

    Home Assistant : Q&A, Tips & Tricks, Your Configs

    The point is that you already have hardware which is capable of controlling the energiser, which can also run ESPHome. The only gap is tracing the pinout from the ESP32 to the various outputs/intputs, so you know what pins to assign to what function. Understanding that not everyone is as...

    That top board looks like it already has an ESP32 WROOM on it (top center). Some close up photos would indicate whether it does, and exactly what its purpose is. It may alternatively be a Tuya module, but either way, it may be possible to make an ESPHome firmware to replace its built-in...

    What I really meant was: which municipality is allowing feed-in? Does the feed-in tariff make it worth while doing, rather than having more battery capacity?

    Curious how you are exporting so much energy to the grid. Do you have a smart meter, and how much do you get in return?

    There was mention of it identifying the dongle on your network, but I have no idea what it does after that! 👀

    Port MTN mobile to VoIP?

    Vodacom offers eSIM, presumably MTN does as well. Convert your physical SIM to an eSIM, load it into your iPhone. The trick is to keep your MTN number alive, usually at the lowest possible cost. Generally, that requires converting to prepaid, and maintaining the balance of the account in a...

    Reading your solar config/README, I thought you might also be interested in my conversion of the ShineWifi-F dongle to run ESPHome directly: https://powerforum.co.za/topic/32073-growatt-shinewifi-f-reflashed-with-esphome/ Also, as an alternative to including the modbus configuration in the...

    (@Zuluzebra may also be interested.) I made a simple PCB with 6 isolated inputs and 4 isolated outputs, all controlled by an ESP32. It's designed to "supervise" a garage door motor, or gate motor, but should be perfect for an electric fence as well, so long as you keep it some distance away...

    SA households with batteries connected to Deye inverters could get paid R1,000 to R2,000 per year for sharing their storage

    This is an interesting development. https://techcentral.co.za/blu-label-400mw-electricity-plan-projects/285358/ I could see Blu Energy partnering with Deye to track actual energy sent back to the grid ...

    SA households with batteries connected to Deye inverters could get paid R1,000 to R2,000 per year for sharing their storage

    TLS over TCP/IP to the WiFi dongle is one thing. But the inverter doesn’t talk that natively. The dongle talks modbus over rs232 to the inverter. Which has no security to speak of, unless they have implemented something non-standard over and above what the dongles are currently doing.

    SA households with batteries connected to Deye inverters could get paid R1,000 to R2,000 per year for sharing their storage

    Mmmm, I have heard of this IoT. In reality, it's just a bunch of computers talking to each other, and if one computer says something, the other computer needs to verify that what it says is correct. As an information security practitioner, I know all about making computers do things their...

    SA households with batteries connected to Deye inverters could get paid R1,000 to R2,000 per year for sharing their storage

    Curious to know how they verify that you are actually charging or discharging as instructed, Sounds like you could make a device that looks like a Deye inverter, and reports reasonable charge/discharge/SoC figures, but doesn't actually do anything at all. Not that I'm advocating that anyone...
