They use our WiFi network now, which they can reach.

I was told 100meters!

@@TheRainHarvester haha they lied to you. Unless you build a strong antenna specific for thr radio frequency that has an antenna port from the chip. But then you might as well use LORA

@@crouchingchicken007 i think the guy with the Swiss accent told me. He actually tests stuff. Oh Maybe his was esp32...

@@TheRainHarvester haha I follow him too. Nevertheless, these are all esp32 the espnow protocol is weak. I've developed a few use cases and was limited by the distance of the signal if we kept everything as is and using on board RF of the chip. Nothing more than 12 meters distance in fairly open areas

That is what it does. It makes it useful for infrequently updated displays like the children's scoreboard. But things like putting a clock on it or a "time since last update" timer would not be practical.

Behaviour differs between v1 and v2 of the display, with v1 looking more complete in this regard. Update code at github.com/pimoroni/inky-phat/blob/master/library/inkyphat/inky212x104.py#L138 I'll have to look at the data sheet to understand it. I can imagine working at this low level it's possible to achieve a fair amount. We see at this line (at time of me writing this comment) that V2 can't work in partial mode. Partial mode would have made things better for me, being able to update a "Last reading taken at" clock while not flashing the main display if nothing has changed. github.com/pimoroni/inky-phat/blob/master/library/inkyphat/inky212x104.py#L328
