  • Definitely one of the “throw it on the pile” projects for me, too, but I’m for sure throwing it on the top of the pile. Have had quite a few severe storm warnings this year already and this could be pretty useful. I was originally just looking for a way to forward NWS/EAS alerts to Meshtastic from the internet, but getting them direct over-the-air is even better.

    Only complicating factor is I have to fashion or buy an antenna for ~150 Mhz since I don’t have any adapters that will fit the RTL-SDR (I’ve just used the little stock UHF TV antenna that came with it for ADS-B and other playing around).







  • This is from memory and anecdotal, so take it with a grain of salt.

    On firmwares below 2.7, I think it only stored the last-received message on the node itself. 2.7+ may store the latest message from up to a few different contacts, but not more than that (if even that). Either way, it’s not really meant to operate as a “mailbox” where you can retrieve the messages later; they basically need to go somewhere as they’re received.

    There’s a store-and-forward mode that can be enabled, but it stores all messages for everyone and is more of an infrastructure node role. It also requires hardware that has PSRAM which the Heltec V3’s don’t have.










  • True, but I’ve had two grid-tie inverters, and both have had anti islanding protection and would not function when there is no utility power. Pretty much all grie-tie inverters have that protection.

    I’m specifically referring to the interconnect agreement, though, which is where you have to jump through a bunch of hoops, fill out a bunch of forms, pay a fee, wait for the power company to come and inspect it, and get the utility provider’s blessing before you can hook in a grie-tie inverter and export even a fraction of a watt.

    And you have to go through that process every time there’s a change to your system. e.g. If I start out with a 400 watt balcony solar kit, get that approved, and want to add another 400w kit, I would have to file new paperwork, pay another fee, wait for inspection, etc.

    I’m all for reasonable safety measures, but the power company in my area is clearly doing all it can to pay lip service to “yes, we support balcony solar” while also making it as painful as possible for homeowners to actually implement it.
