The receiving IC is a [VS838](https://datasheetspdf.com/pdf-file/796250/ETC/VS838/1). Thus it would need to be desoldered and replaced with a [SFH309FA](https://docs.rs-online.com/0d92/0900766b814f56a7.pdf), for instance? But still strange to me that using IRsend/IRrecv module from...

I'd try to simply connect SFH309FA to the same pin where VS838 is connected at the moment. I assume it's directly hooked up to GPIO14 from ESP. Maybe no bit...

I'd also like a CC1101 driver in Tasmota. I suggest to implement it like SML does with ModBus (so also similar to culfw): It would then offer a device descriptor...

But there are **two working configurations**. And whether it works or not only depends on the order of meter descriptions - there is **no** reconfiguration on the hardware side. I...

With my solution I had code size, RAM and network impact in mind. Two k/v pairs per metric is a much cleaner approach of course but has [less likelihood of...

With `blkCnt: 18`I get `valg alloc mmz buffer failed!`. With `blkCnt: 17`I see `Free MMZ mem before allocation: 31868KB` `Free MMZ mem after allocation: 8372KB` `Free MMZ mem finally: 520KB`...

The important thing: with `blkCnt: 10` I still can't take yuv420 image.

I have a similar problematic watermeter (even though not that bad) and experience the same situations: neg. readings.
