OK. Thanks Dave. I think I will upgrade to using the one Pi4 that I have. It has 4GB of ram, so it should be fine with the 64bit stuff installed. Question: When I look at the flows in the FILES

The 1 GB RAM will probably be a little slow, not so much the Pi3. I’d recommend a Pi3B with 4 GB RAM as minimum if you are going to do 3 or more flows. I am running two Pi 5 8GB here. One for my

Hi Alan.? That's quite a catch.? I never would have thought of that.? Thanks for the nice little flow that can fix my images.? I've tried a few with moderate success but now it's just a matter of

Hi: I have been away from node-red since 2020.? Back then, I was using the VITA49 and Flex Radio V6 flows that Dave shared, on a RPi 3B+. ?? I have that all working again as of yesterday. ? ? (I

I have several idle RPi 3B+ units.? But they have only 1 GB of RAM. My old 2020 RPi3 node-red unit ran just fine with 32bit OS and 32bit .net install. If I build a new fresh install with Pi OS

Ken You cannot have strings within strings. SVG uses "SVG code" in its code, but node-red sees this as a sting...... Other than the opening and closing "" for the code, because the full code is a

Hi Alan.? I think I am getting the concepts.? My issue right now is finding a way to format the svg data.? I have tried several editors and converters but can't get a clean svg image or at least

Definitely do a backup by exporting all flows on a regular basis. SD cards can fail without notice. And while we are on the subject… If you rather do a clean install instead of upgrading an old OS

Hey Warren.? I had no idea i could have the context "persist" across startups.? That's a great technique and I'll set it up.? I also see how Alan is building the graphics nodes although I have to

Ken Excellent.? Glad you persisted with solving the issues and now have a better idea of what is going on! Yes, the boundary condition of not knowing all of the button contexts at startup is

I last used my Node-Red Raspberry Pi in 2020 at a previous home. I just now dug it out, and it boots ok and works. But naturally, after 4 full years, Pi-OS is offering updates and upgrades. Does the

Hey Guys. I'm overwhelmed by the generosity of the group members in trying to educate me.? I'm taking it all in and now have a working flow with the buttons changing color as Warren showed.? I have

Hey Ken, Glad you have made progress!? ?Alan has extended my "Create Basic Button" idea to have more of the fun graphic stuff, which is what I was implying could be done. I'll let Alan keep guiding

Ken I have attache a demo flow you can use to follow along below. First, for sending images to the buttons, you must send the following object.

Hi All.? Warren, I got your flow to work.? The problem I was having is that I assigned a graphic to the SD buttons at design time.? I guess this does not get overridden by the output of the NR

Alan and I were discussing this on the phone earlier. If the equipment you are controlling (example - Antenna Genius) sends status updates or can be queried for status, then that should determine what
