New option : Output message update on every input message

Add option for updating msg output for every input message recived. This will increase reliability if hysterisis node controls a device over communications which is unreliable. Eg if first message fails to transmit, then hysterisis node will send a new one on next msg input.

Error when "Thresholds missing"

Hello Sineos!

If threshold type is dynamic, and something is changed in code causing node redeployment, node shows "Thresholds missing" after deployment and does not output anything when next current value is received. After setting threshold all is fine of course.
Could it be possible to add some error message so it can be caught in the code in next node?
Thanks for the node!

'Send initial message' within hysteresis band

This component is very useful, thank you.

An enhancment would be to ensure, that with 'Send initial message' active, you always get an initial message. This is currently not the case, if the value is within the two theresholds at start. The explanation is that this is because the previous value is unknown, which is correct. For the proposed enhancment, you would need to add a parameter with the desired default value, i.e. 'Default initial level' that would let you choose ' Upper Threshold' or 'Lower Threshold' or 'nothing'. Then the documentation would say:

"Send initial message will simply match the first valid value against the lower or upper limit and send an output if any of the levels is exceeded respectively underran. If the first valid value is in between the lower and upper limit, send an output according to the 'Default initial level'".

dynamically sending upper threshold and lower threshold setpoints

Hello.

Can you please provide an example flow or more information on how you can send a message to change the upper and lower trigger thresholds .

Thanks
