Thanks so much for the info!
I’ll give this a try and see if it works. I have also bought a broadlink RM because i was having issues with the Wemos and IR Shield so i’ll see if i can get it to work with either. I’m also not 100% sure if my Rinnai heater supports IR. It has a remote holder but I can’t locate a receiver or a mention of it in the heater manuals.
If anyone comes across this looking for Rinnai IR codes, they need to be converted for newer versions of ESPHome due to the NEC bit order change mentioned in the docs. Unfortunately the method used by the examples in the docs doesn’t work, so you need to use the method described here.
Updated Rinnai heater codes for anyone looking for them:
Has anyone used these codes with Tasmota IR? I use a rechipped Blitzwolf IR sender. The code I send over mqtt is: {"Protocol":"EPSON","Bits":32,"Data":"0xA55A38C7","DataLSB":"0xA55A1CE3","Repeat":1}
Thats to power on my old Pioneer amp.
