I’ve used this blueprint successfully in the past but now cannot. It relies on a 500 character text helper. When setting up the blueprint, it says:
Input Text used to store the last event fired by the controller. You will need to manually create a text input entity for this, please read the blueprint Additional Notes for more info.
I can’t find the additional notes with guidance anywhere. My understanding is that the original workaround to increase text helper max length beyond 255 was patched last month.
What’s the best way to make the blueprint work in the meantime? As currently defined, I don’t think I can point it at another object (ie. a templated sensor) to store the data, because it insists on a text helper. Back in 2021 there was discussion of using an attribute to do this, but enough has changed in Home Assistant in the last 4 years that none of the guidance remains relevant – and I’m not sure this blueprint would even work with that.
Edit: answering my own question. I’m sure there’s a good reason you shouldn’t do this, but there seem to be a bunch of reasons (1, 2) you need to. I patched .storage/input_text directly on the HA filesystem to increase the max value, then restarted… and all good, it works great now.
